Best offer on record: Claude Startups program (free Claude Team year + $1,000 API credit, Oct 2026 expansion). 18 verified findings, checked 2026-10-22.
Live check of “AI for Science program — up to $20,000 API credits for 6 months (researchers/education)”:Partly confirmed
Anthropic's AI for Science program exists and is still open on a rolling basis (applications reviewed the first Monday of each month, no deadline): the help center page (dated March 16, 2026) states "up to $20,000 in API credits" for a 6-month period to researchers in academia and nonprofit organizations attached to research institutions, credits for API use only. However, Anthropic's newer official announcement of August 27, 2026 (anthropic.com/news/expanding-support-for-scientists) expanded the program and says researchers "can apply to our AI for Science program for up to $50,000 in credits per project" with "Any researcher is eligible to apply", so the $20,000/6-month figure is the older, un-updated tier rather than the current maximum; the separate rare-disease call ($50,000 over six months, deadline Aug 2, 2026) has closed.
Claude Startups program (free Claude Team year + $1,000 API credit, Oct 2026 expansion) high confidence
Launched May 2026 (originally invite-only via partner VCs; self-serve form added 21–31 May 2026). On Oct 6, 2026 Anthropic expanded it: (a) one free year of Claude Team with up to 5 Premium seats for companies new to Team (~$6,000 at the $100/seat/mo list price), (b) a one-time $1,000 API credit 'available as soon as you're approved', (c) 'Claude Startup Stack' partner discounts/credits worth up to $45,000 (combined partner max, not a cash grant), (d) up to $100,000 in additional API credits claimable through partner VCs, (e) 45-min Applied AI office hours biweekly, Claude Marketplace listing help, Founder House/events. Combined Claude value 'up to $7,000'. After a surge of '21x the expected applications' (hundreds of thousands), the free Team + $1,000 credit offers were paused ~Oct 9–13 and all applications are being re-reviewed; as of today the official page says 'Our current cohort is now full, and we're not accepting new applications right now.' Existing claimed offers are unaffected. Credits apply only to the first-party Claude API via Claude Console — not AWS Bedrock, Vertex, Azure or other third-party platforms.
Eligibility
Startups 'founded in the last five years or funded in the last two' (Oct 2026 expansion wording). Bootstrapped, pre-seed and VC-backed companies may apply. Older FAQ text for the credits tier additionally required institutional equity funding, founding within 4 years, and no prior Anthropic startup credits. Requires a Claude Console account and a company email matching the company's website domain. Geographic exclusions in the official program terms (last updated May 22, 2025): Belarus, China, Cuba, Iran, Myanmar, North Korea, Russia, Sudan, Syria, Crimea, DNR/LNR; Anthropic-affiliated persons excluded. No .edu email; no CC requirement stated.
How to claim
1) Sign in to Claude Console; 2) submit the application at claude.com/programs/startups (currently closed — cohort full); 3) if approved, $1,000 credit and Team year activate automatically; 4) if funded, mention/partner with a partner VC for up to $100K additional credits. To hear when the next cohort opens, subscribe to the Claude Startup newsletter.
Expiry
Cohort currently full / paused as of 2026-10-22; next cohort TBA. Secondary coverage reports the $1,000 API credit expires six months after it is granted; Anthropic's general Credit Terms (cited by a Sept-2026-checked tracker) say promotional credits otherwise expire one calendar year from issuance. No published sunset for the program itself.
Gotchas
Trial-vs-free: the 'free year' is a subsidized paid-plan grant, not a permanent free tier — after it lapses the account bills at list price. The $45K figure is max combined partner value, not a grant. Credits are first-party-API only (Bedrock/Vertex not eligible). The free offers were paused within days of launch due to capacity; applying now = waitlist. VC-linked $100K tier is separate from the $1,000 and goes through the investor, not a direct Anthropic award. One award per company.
Claude consumer Free plan (claude.ai) — free tier, no card high confidence
The Free plan is $0/month: chat on web/desktop/mobile, web search, file creation, code execution, memory, connectors, Artifacts, Design/Slides/Docs. Verified today on the official pricing page: no credit card required ('Free: $0, no card required'). Paid plans: Pro $17/mo annual ($200 up front) or $20/mo; Max from $100/mo. Team Standard $20/seat/mo (annual) / $25 (monthly); Premium $100/seat/mo (annual).
Eligibility
Anyone; consumer account, no eligibility check beyond account creation. No .edu email. No CC required for Free.
How to claim
Sign up free at claude.ai (or download desktop/mobile app). Nothing to claim — account creation is the entire step. No API keys: the Free plan provides chat-app access only, not the first-party API.
Expiry
Ongoing; no sunset date published.
Gotchas
Not an API offer — students/startups building products cannot use the Free plan as API compute; usage limits apply (rolling 5-hour session windows, weekly caps on paid tiers).
Small free API trial credits for new users (official FAQ) high confidence
The official API pricing docs FAQ (read today): 'New users receive a small amount of free credits to test the API. Contact sales for information about extended trials for enterprise evaluation.' Also: 'Academic and research discounts might be available' (under Volume discounts). The dollar amount of the signup credit is not published on the page.
Eligibility
Any new API account (platform.claude.com console). Extended trials via sales are for enterprise evaluation; academic/research discounts are on a may-be-available basis.
How to claim
Create a Claude Console account at platform.claude.com; the small free test credit attaches to the account automatically (amount unpublished). For extended trials, email sales@anthropic.com.
Expiry
No stated expiry for the small trial credit; purchased/other credits expire per Credit Terms (promotional credits within one calendar year of issuance per a Sept-2026-checked secondary tracker).
Gotchas
A Sept-2026 third-party tracker claimed new API accounts get 'no free credit at all', which the official docs FAQ contradicts (or the small credit may not appear in every region/account — amount is unpublished, so treat as small and unspecified). A CC is needed to go beyond the free credit; billing is arrears-based.
AI for Science program — up to $20,000 API credits for 6 months (researchers/education) high confidence
Official support article (read today): approved applicants get 'up to $20,000 in API credits to your account for a 6-month period.' Credits are for API use only ('do not apply to the Claude web app'). Launched May 5, 2025; particular focus on biology/life sciences. Review: 'We evaluate submissions on the first Monday of each month.' Single account per research program; credits allocated to one organization ID and distributed among collaborators.
Eligibility
Researchers attached to a research institution working on high-impact scientific projects (academic/nonprofit). Reviewed on scientific merit, impact, feasibility, plus biosecurity screening. No .edu email explicitly stated (institutional affiliation is the gate).
How to claim
Fill out the linked Google Form application on the AI for Science page (from the official support article at support.claude.com/en/articles/11199177 or the launch page at anthropic.com/news/ai-for-science-program). If you need models sooner, create a Console account in the interim.
Expiry
Credits valid for 6 months from grant; monthly review cycle; no program sunset date published. No nonpublic/experimental models through this program.
Gotchas
No Usage Policy exemption (red-teaming/jailbreaking research still subject to standard enforcement); rejections get no individual response; 'substantial number of applications' — competition is high; no finetuning API access via the program (finetuning preview is AWS Bedrock-only).
Claude Team plan for Scientists — free Standard seats for university/nonprofit research groups high confidence
Official page (read today): Principal Investigators (or equivalents) at accredited universities and nonprofit research institutes in natural sciences, math, CS, engineering and related fields get the Team plan at promotional pricing: Standard seat $0/month (regularly $20), Premium seat $15/month (regularly $100, 5x usage), 1–25 seats per group (contact us for larger), min 1 seat. '10,000 scientists around the world can now get Claude at no cost to start.' Includes Claude Science, Claude Code & Cowork access, SSO, shared projects, database connectors. 'Claude does not train on your conversations, uploaded files, or research data.'
Eligibility
PI/equivalent at an accredited university or nonprofit research institute; for-profit, CRO and industry R&D teams are steered to paid plans. No .edu email required — institutional type + attestation (claude.ai/labs-verification/attestation: confirm affiliation + brief research description). Reviews take 5–7 business days.
How to claim
On claude.com/programs/team-plan-for-scientists: click 'Verify now' → complete the attestation → approval email → add seats immediately. For extra API credits, apply to the AI for Science grant program (separate application).
Expiry
Promotional pricing applies 12 months from sign-up, then seats renew at the then-current price for this plan. Inactivity clause: 'If a group has no activity for 90 days, we may return it to standard Team pricing' (admins notified first). Limited availability — pricing not guaranteed.
Gotchas
This is a discounted plan, not free credits — after 12 months you pay list price if you continue. No bundled API credit amount: extra usage is grant-based via AI for Science. 'Final pricing confirmed after verification' — expect surprises on larger groups.
Claude Campus program — student ambassador tracks with USD 3,600 stipend high confidence
Official page (read today): three student tracks, each with a flat 'USD3,600 cash stipend' (subject to program terms) and access to Anthropic-run workshops: Undergrads → Claude Builder Club (run a campus AI builder club, guest speakers, hackathons; resources shared with members include 'API credits', amount not specified); Grad students → Claude Campus Conversations (AI-and-society discussion groups, office visits); PhD/Postdoc → Claude Science workshops (researcher community, 'Claude for Science workshops'). 'Applications open September 1 and close September 12,' rolling review; program runs 'from September 2026 to June 2027' as a full school-year program. 'No. It's free to apply and free to participate.' Current status: 'The program is closed for Fall 2026.'
Eligibility
Students anywhere in the world; 18+ with work authorization in the country of study; 'AI fluency and Claude proficiency' expected but no expert background; grad/PhD tracks 'may select from a smaller pool of schools' during the pilot. No .edu email or student ID explicitly stated. No expert AI background required.
How to claim
Apply during the stated window (Sep 1–12 of the program year) via the page form at claude.com/programs/campus; rolling review; returning ambassadors must reapply and flag prior status. The current Fall 2026 round is closed — watch for the next cycle's announcement.
Expiry
Program year runs Sep 2026–Jun 2027; closed now (Fall 2026 round ended Sep 12, 2026); no automatic renewal — past ambassadors reapply each cycle. Next cycle date not published as of today.
Gotchas
The stipend is a cash payment for ambassador work (club/event running), not a research grant. 'API credits' shared with undergrad club members have no published dollar amount. 'Work authorization in your country of study' may limit international students without local work rights.
Claude for Teachers — free premium features for US K-12 educators high confidence
Official page (read today): 'US K-12 educators and districts get free access to premium Claude features, like teaching skills and a connection to evidence-based curricula.' Includes curriculum connectors (e.g., Learning Commons), teaching-workflow skills; 'Models are never trained on your conversations.' Districts get centrally managed accounts with RBAC and SSO plus K-12 terms and a student data privacy agreement. 'Sign up by June 30, 2027 for your full year of free access.' 'Extra usage limits apply.'
Eligibility
US K-12 educators and school districts only (region-limited to the US). Individual teachers verify identity at claude.ai/teachers; districts enroll 'every educator on your school or district domain.' No .edu email requirement per se (verification-based).
How to claim
Teachers: click 'Verify now' on claude.com/solutions/teachers → identity verification at claude.ai/teachers. Districts: district-domain enrollment (K-12 terms/privacy agreement).
Expiry
Sign up by June 30, 2027 for a full year of free access; price/plans subject to change at Anthropic's discretion. Free access duration per sign-up is one school year (rolling annual, per 'full year of free access').
Gotchas
No API access — it's a consumer/education product offering (web/desktop chat), not an API/developer free tier. US-only. 'Extra usage limits apply' — premium features still have caps.
Claude for Open Source — 6 months of free Claude Max 20x for maintainers high confidence
Official page (read today): '6 months of free Claude Max 20x' — a subscription for the Claude apps and Claude Code, not an API credit. Overage beyond Max limits billed at standard rates; when it ends 'your account returns to the free plan' (or resumes prior paid plan). Six qualifying thresholds (any one): (1) 500+ dependent repos or 100+ dependent packages, or 200,000+ combined monthly registry downloads; (2) committer/maintainer of a recognized foundation or language project (CPython, Rust team, Node.js TSC, Apache PMC, CNCF, Kubernetes, Linux kernel, Django, Rails, or similar); (3) 100+ merged PRs into repos you don't own in the last 12 months; (4) one of your repos with 20+ unique external contributors (merged PRs, last 12 months); (5) OpenSSF criticality score >= 0.4 on a repo you maintain; (6) discretionary 'ecosystem impact' catch-all. Baseline requirements (secondary, Sept-2026-checked): GitHub account 2+ years old, public activity in prior 90 days, OSI-approved license, 18+. A Sept-2026-checked tracker adds: cap of 10,000 approved recipients and a 90-day activation window on the approval link.
Eligibility
Open-source maintainers/contributors meeting one threshold; not limited to students or startups — relevant to students who maintain OSS projects. Criteria were overhauled in July 2026 (the older '5,000+ stars / 1M+ npm downloads' gate was replaced by these six thresholds).
How to claim
Apply now at claude.com/contact-sales/claude-for-oss ('Apply now' CTA; form mechanics beyond that not detailed on the page). Approved maintainers get an activation link (use within 90 days per secondary source).
Expiry
Subscription lasts 6 months; 'complimentary subscription ends' with a reminder email beforehand; account falls back to Free plan after. No program sunset date published.
Gotchas
Subscription, not API credit — does not fund API-based products. Overage after Max limits costs standard Max rates. A separate linked Terms document (anthropic.com/claude-for-oss-terms) governs details not shown on the page.
API code execution free hours (platform feature, de-facto free tier) high confidence
Official API pricing docs (read today): the code execution tool — used without web search/web fetch — gives 'Each organization receives 1,550 free hours of usage per month' (equivalent to the pricing page's '50 free hours of usage daily per organization'); beyond that it's $0.05/hour per container, 5-minute minimum. Also: 'Code execution is free when used with web search or web fetch' (no extra charge beyond token costs).
Eligibility
Any organization/account using the first-party API (console account); no CC-only gate mentioned for the feature, but API billing overall is arrears-based and a payment method is needed for charged usage.
How to claim
Use the code execution tool in API requests; the free 1,550 h/month allotment applies per organization automatically.
Expiry
Ongoing monthly allowance; no sunset published.
Gotchas
Token usage (input/output) is still billed normally — the free part is container runtime only. If files are included in the request, execution time is billed even if the tool isn't called (files preloaded onto the container).
Claude via AWS Bedrock using AWS Activate credits (startup free-compute route) medium confidence
Anthropic's own program excludes Bedrock/Vertex for its credits, but startups can reach Claude through AWS Activate: founders tier $1,000–$5,000 self-funded (pre-Series B, founded within last 10 years; AWS says 'you'll hear back within 5–10 business days'); portfolio/VC-accelerator tier up to $200,000 via a VC or accelerator with an AWS Org ID; invite-only 'AWS Credits for AI Startups' tier $200,000+. The AWS Activate FAQ (checked Sept 2026) states credits 'are also redeemable for third-party models on Amazon Bedrock... like AI21 Labs, Anthropic, Cohere.' Counterpoint: Google for Startups credits are NOT usable for third-party models on Vertex, and Microsoft Foundry docs list credit-based accounts as unable to use Claude — so AWS is the viable credit path to Claude on a hyperscaler.
Eligibility
Startups pre-Series B, founded within the last 10 years (AWS Activate); US global eligibility per AWS program terms; region limits apply to AWS accounts. Not a student program (student routes on AWS are separate, e.g., AWS Educate — not verified today).
How to claim
1) Apply for AWS Activate at aws.amazon.com/activate (self-serve or via your VC/accelerator); 2) claim the Org-ID-based credits; 3) enable Amazon Bedrock in your AWS account and select Anthropic Claude models; 4) spend Activate credits on those model calls.
Expiry
Activate credit expiry is per-AWS-timer rules (typically fixed windows per tier, not re-verified today). No Anthropic-side expiry on Bedrock usage; AWS Bedrock usage pricing differs from first-party API pricing.
Gotchas
Secondary source (checked 2026-09-25) — re-verify amounts on aws.amazon.com/activate before relying on them. Bedrock Claude pricing, rates and model availability differ from the first-party API; egress/data-transfer and Bedrock service fees can erode the credit value (data/egress costs gotcha). Anthropic startup credits cannot be used on Bedrock/Vertex — the two credit pools don't mix.
External Researcher Access program — $1,000 API credits for AI-safety researchers low confidence
A Sept-2026-checked tracker lists 'External Researcher Access: $1,000 in API credits' for AI safety researchers, reviewed monthly, with 'more for rare special cases.' The official page could not be located today (candidate URLs 404'd; the claude.com programs footer lists only Campus, Frontier Academy, Scientists, and Startups), so treat the dollar figure as unverified against a primary source.
Eligibility
External AI-safety researchers (individuals/researchers, distinct from the institution-based AI for Science program); exact criteria not published on a locatable official page as of today.
How to claim
Per the secondary tracker: submit a short application/request for external researcher access (monthly review); if approved, $1,000 in API credits is added to the account. Locate the canonical form via Anthropic support or the AI-safety research channel.
Expiry
Monthly review cycle; no published sunset.
Gotchas
Secondary-source only — the amount and even the program name may have changed by now; do not quote it as official without re-verifying.
Menlo Anthology Fund — investment + Anthropic credits for pre-seed/Series A startups medium confidence
A $100M fund run by Menlo Ventures with Anthropic: investment 'starting at $100,000' at pre-seed through Series A, bundled with Anthropic API credits. The fund's own page was internally inconsistent when checked (Aug 2026): body text says '$25,000 in free credits' while its FAQ says '$30,000 in free Anthropic credits.' Applications via an Airtable form on a rolling basis; Menlo promised responses within two weeks.
Eligibility
Pre-seed to Series A startups picked by Menlo; equity is taken (it is an investment, not a grant).
How to claim
Apply via the Airtable form at menlovc.com/menlo-anthology-fund/; if selected, the investment closes with bundled Anthropic credits. Alternatively, startups already backed by Anthropic's partner VCs can claim up to $100,000 in additional API credits 'through your VC' (stated on the official Claude Startups page read today).
Expiry
No published sunset; application form rolling; page last updated Aug 2026.
Gotchas
Equity dilution cost — this is a venture investment, not a free grant. Credit amount conflict ($25K vs $30K) on the fund page; confirm at close. The VC-claim path for up to $100K (official Claude Startups page) is the better-verified number.
Claude for Startups program (credits + VC top-up) high confidence
Program members access 'discounts and credits worth up to $45,000 from companies building with Claude' (offers from AI-native vendors across sales, design, data, meetings, engineering; each redeemed with a code in the Claude Console). Founders backed by a VC in Anthropic's partner network may receive up to $100K in ADDITIONAL first-party API credits, claimed through their VC. Members also get biweekly Applied AI webinars/AMAs and invites to Claude Startup events/hackathons.
Eligibility
Early-stage founders. Page states no explicit company-age cap, funding ceiling, minimum team size, .edu requirement, or region limit. The $100K is gated to founders whose VC is in the Anthropic partner network. CURRENT COHORT IS CLOSED: 'our current cohort is now full, and we're not accepting new applications right now' as of today.
How to claim
Non-members: subscribe to the Claude Startup newsletter to be alerted when the next cohort opens. Existing members: sign in via Claude Console at platform.claude.com/claude-for-startups. The $100K VC credit is claimed through the VC, not the general application.
Expiry
No published expiry/validity window for member credits. Benefits run on a membership/cohort basis. Upcoming dated event: Claude Founder House, San Francisco, Oct 6-8, 2026.
Gotchas
Credits apply ONLY to the first-party Claude API via Claude Console and CANNOT be used on AWS, Google Cloud, Azure, or other third-party platforms. The program is cohort-based and applications are currently closed (must wait for the next opening). Trial-style, membership-gated, not a self-serve signup.
Claude.ai Free tier (consumer, no startup needed) high confidence
Free Claude account: $0, 'Free for everyone'. Includes chat on web/desktop/mobile, web search, file creation, code execution, memory, Artifacts, Design, Slides, Docs. Projects capped at up to 5. Available models on Free: Sonnet and Haiku only (no Opus).
Eligibility
Everyone (no account prerequisites). No .edu required, no startup status required. No credit card required (listed 'n/a').
How to claim
Sign up at claude.ai; select the Free plan.
Expiry
Ongoing; not a time-limited trial. Standard per-model usage limits apply (no fixed message count published; Anthropic links to a usage-limit-best-practices article).
Gotchas
No Opus access on Free. Distinct from the paid Pro ($17-20/mo) and Max ($100+/mo) plans which DO require a credit card. Consumer chat product, not API access.
There is NO free API tier and NO standalone free API trial credits listed on the official pricing page today. API access is pay-as-you-go (e.g., Sonnet input $2/MTok, output $10/MTok). The $45K startup credits and the 'Team plan for scientists' are the free-ish routes to API usage.
Eligibility
API requires a paid account / credit card. Free API use is only via the startup program credits or the scientist plan.
How to claim
Create an account in Claude Console (platform.claude.com) with a payment method; to use API without paying, qualify for the Claude for Startups program or the Team plan for scientists.
Expiry
n/a (no free tier to expire).
Gotchas
New API accounts need a card and are billed usage (data/egress/token costs apply). Anthropic historically offered a small free API trial credit for new accounts; that is NOT listed on the official pricing page as of 2026-10-22, so do not assume a fresh sign-up gives free API credit.
Claude Team plan for scientists (free academic/nonprofit research seats) high confidence
Standard Team seats at $0/month (list $20; annual $0/$180 per seat); Premium seats $15/month (list $100). '10,000 scientists around the world can now get Claude at no cost to start.' 1-25 seats per group (contact for larger); Premium adds 5x usage; extra usage via the AI for Science grant program.
Eligibility
Principal investigators (or equivalent) at ACCREDITED UNIVERSITIES and NONPROFIT research institutes in natural sciences, math, CS, engineering and related fields. For-profit companies, CROs, and industry R&D teams are EXCLUDED.
How to claim
Verify institutional affiliation at the 'Verify now' attestation link; confirm affiliation + brief research description; most applications reviewed within 5-7 business days; on approval admins add seats.
Expiry
Promotional $0 pricing lasts 12 months from sign-up, then seats renew at the then-current plan price; inactivity for 90 days may return the group to standard Team pricing; 'promotional pricing is not guaranteed, given limited availability.' No calendar dates published.
Gotchas
Requires an accredited-university / nonprofit-researcher affiliation (institutional, not just any .edu personal email). Cap on 10,000 scientists and limited availability. Renewal ends the free window after 12 months.
Claude for Teachers (free K-12 educator access) high confidence
US K-12 educators and districts get FREE access to premium Claude features (teaching skills, evidence-based-curriculum connectors aligned to state standards, e.g., Learning Commons). Individual teacher account: free, premium features, extra usage limits apply, no numeric cap published. District tier: centrally managed accounts with RBAC/SSO, K-12 privacy agreement.
Eligibility
US K-12 educators and school/district leaders. Verified via claude.ai/teachers (individual) or claude.ai/k12districts (districts). US-focused.
Sign up by June 30, 2027 for a full year of free access; terms/price subject to change at Anthropic's discretion afterward.
Gotchas
US-only K-12. 'Extra usage limits apply' (no published numbers). Free annual window is tied to the June 30, 2027 sign-up deadline. Privacy: model training off by default for verified educators; FERPA/AFT Gold Standard oriented.
Education / university license (institutional, not free self-serve) medium confidence
A 'comprehensive university-wide plan' covering students, faculty, and staff at discounted (institutional) rates, with dedicated API credits and educational features for student learning, plus training/enablement. No specific dollar discount/seat count/percentage published; it routes to 'Contact our Education team' (/contact-sales/education-plan). Named partners include Dartmouth, UVA, U Pittsburgh, Northeastern, Syracuse, LSE, Champlain, Northumbria, USF.
Eligibility
Institutions purchasing an education plan (the .edu/affiliation benefit is institutional, not an individual free claim flow). No self-serve .edu sign-up or free student tier is offered on these pages.
How to claim
Institution contacts the Anthropic Education team via /contact-sales/education-plan; there is no individual student free-claim flow.
Expiry
No published expiry. Ongoing commercial offer.
Gotchas
NOT a free self-serve license — it is a paid institutional plan (discounted), so it is not a free offer in the same sense as the Free tier or the scientist/teacher plans. No student-per-seat free access is published.
As of 2026-10-22, confirmed today on official pages: (1) Claude Startups was EXPANDED on Oct 6, 2026 (free year of Claude Team up to 5 Premium seats + $1,000 one-time API credit + $45K Startup Stack + up to $100K via partner VCs), but within days (~Oct 9–13) Anthropic PAUSED the free Team/credit offers after ~21x expected applications ('currently over capacity'; all applications re-reviewed), and the official page now (Oct 22) says 'Our current cohort is now full, and we're not accepting new applications right now' — the program continues for existing members; the benefit line items were dropped from the live page. Next cohort is TBA (newsletter signup is the only official channel). (2) The original Claude Startups invite-only (partner-VC-link) model of early 2026 was replaced by a direct self-serve form between May 21–31, 2026; older guides describing the VC-link flow are outdated. (3) Claude for Open Source criteria were overhauled July 2026: the 5,000+ stars / 1M+ npm-downloads gate no longer applies, replaced by the six usage/maintainer thresholds now on the official page. (4) Claude Campus is closed for Fall 2026 (application window Sep 1–12, 2026; program runs Sep 2026–Jun 2027; next cycle not yet announced). (5) Claude for Teachers: sign-up deadline June 30, 2027 for the free-year. (6) Nothing was sunset for the consumer Free plan or the API docs' 'small free credits to test the API.' General credit terms (secondary): promotional credits expire one calendar year from issuance; the Oct 2026 startup $1,000 credit was reported to expire six months after grant — the two sources conflict, re-verify per-award. Also note: Anthropic no longer maintains a public 'startup program official terms' page beyond the May 22, 2025 version; the active program now lives under claude.com/programs/* and the domain rebranded anthropic.com → claude.com (301 redirects), so some archived anthropic.com URLs now 404 or redirect. Research caveat: the session's web-search budget was exhausted mid-run; all primary claims above were verified by direct fetch of official pages today (claude.com/pricing, claude.com/programs/startups, /campus, /team-plan-for-scientists, /frontier-academy, /contact-sales/claude-for-oss, claude.com/solutions/education and /teachers, support.claude.com article 11199177, anthropic.com/news/ai-for-science-program, platform.claude.com/docs pricing); items marked medium/low come from the klymentiev.com tracker (checked 2026-09-25) and Oct 2026 press (TechCrunch, CNBC, 9to5AI, Times of India) or the fund's own page (Aug 2026).
As of 2026-10-22 the Claude for Startups program has changed materially from its 2024-2025 form: it is now run in cohorts, and the current cohort is FULL with no new applications accepted, so the $45K/$100K credits are only claimable when the next cohort opens (newsletter sign-up is the only current action). No program is sunset, but two notes: (1) The Claude API no longer lists a standalone free trial-credit offer for new accounts on the official pricing page — free API usage is only via the startup credits or the Team plan for scientists, so any historical small free API trial should not be assumed. (2) Two genuinely free education-side offers DO exist today and are the effective 'education' equivalents of a free tier: the Claude Team plan for scientists (standard seats $0 for 12 months for accredited-university/nonprofit PIs, then renews at paid price) and Claude for Teachers (free premium access for US K-12 educators, sign up by June 30, 2027 for the free year). A university-wide 'education license' exists but is a paid discounted institutional plan, not a free self-serve student offer. WebSearch budget was exhausted this session, so claims above were verified by reading the official pages directly today (claude.com/programs/startups, /pricing, /solutions/education, /programs/team-plan-for-scientists, /solutions/teachers); figures like the $45K/$100K amounts and the $0 scientist pricing were confirmed on the pages, but I could not cross-check third-party news coverage of 2025-2026 changes.
Critic corrections
Anthropic Claude API: Caveat needed (secondary source). No general free API tier was found. Claude for Startups, expanded Oct 6, 2026, now includes a free year of Claude Team for qualifying startups and a one-time $1,000 API credit. Anthropic says it is over capacity on those offers and is re-reviewing applications. Confirm on anthropic.com.
Claude for Startups (Anthropic): Figures are misleading (secondary source). The up-to-$45K figure is partner-offer value in the Claude Startup Stack, not API credit. The direct API credit is a one-time $1,000. VC-backed startups in Anthropic's partner network may get up to $100K in API credits, claimed through their VC, and those credits cannot be used on Amazon Bedrock.
No free API tier or developer credit program: Monthly API credits exist for subscribers: Max 5x gets $100/month, Max 20x gets $200/month, and Team gets $20 per Standard seat or $100 per Premium seat (pooled, capped at $500/month). Claude Startups members get a one-time $1,000 API credit, but applications were closed as of Oct 13, 2026.
Up to $45K in Claude API credits/discounts: The $45,000 is partner discounts and credits for tools from companies building with Claude (the Claude Startup Stack), not Claude API credits. The Claude API credit is a one-time $1,000. Applications were closed as of Oct 13, 2026.
