Gemini API Free tier (Google AI Studio): free-of-charge models high confidence
Free input and output tokens, Google AI Studio access, and 'limited access to certain models' (official pricing page, fetched 2026-10-22). Models marked 'Free of charge' on the Free Tier column include Gemini 3.8 Flash (confirmed in raw text), Gemini 2.5 Pro, 2.5 Flash, 2.5 Flash-Lite, 3 Flash Preview, 3.1 Flash-Lite and other Flash, Live, TTS, transcription, Embedding 2 and Gemma 4 entries (a third-party count says 23 of 35 pricing-page entries are free). Not free: Gemini 3.1 Pro Preview, Gemini 4 Argon, Omni Flash, image models including 2.5 Flash Image, Veo 3.1, Lyria, 2.5 Pro Preview TTS, and grounding on Gemini 3+ models. Free-tier data: 'Used to improve our products' = Yes (paid tier = No). Numeric free-tier limits are NOT published in Google's docs: the rate-limits page says limits apply per project (not per API key), reset at midnight Pacific, are 'not guaranteed', and are shown per project in AI Studio (sign-in required). Third-party figures conflict (2.5 Pro 5 RPM / 100 RPD in several 2026 guides vs 50 RPD in a May 2026 guide; Flash-Lite 15 RPM / 1,000 RPD vs 30 RPM / 1,500 RPD). Treat numeric limits as unverified.
Eligibility
Any Google account to sign in to AI Studio. Official rate-limits table lists Free qualification as 'Active project or free trial'. No billing account or credit card is listed as required for Free tier; Tier 1 is the first tier that requires linking an active billing account. No .edu requirement, no startup age or funding cap. No country restriction appears on the captured pages (an older cached variant of the rate-limits page said 'Users in eligible countries'; unverified).
How to claim
1) Open aistudio.google.com and sign in with a Google account. 2) Create an API key (AI Studio creates or uses a Google Cloud project). 3) Call a free-tier model such as gemini-2.5-flash or gemini-3.8-flash without linking billing. 4) Read the project's live RPM/TPM/RPD limits in AI Studio.
Expiry
No end date published for the free tier. The model lineup changes with model lifecycle (see sunset_notes).
Gotchas
Free-tier prompts and responses may be used to improve Google products; do not send private or regulated data. Spend-based limit is N/A on Free, but RPM/TPM/RPD overages return 429 RESOURCE_EXHAUSTED. The $300 Google Cloud trial credit cannot pay Gemini API in AI Studio costs (official trial doc). Official billing tiers: Tier 1 = link active billing, billing tier cap $250; Tier 2 = $100 paid + 3 days, cap $2,000; Tier 3 = $1,000 paid + 30 days, cap $20,000 to $100,000+. Spend-based limits per rolling 10 minutes: Tier 1 $10, Tier 2 $50, Tier 3 $200. Gemini 3.1 Pro Preview and Gemini 4 Argon are paid-only.
Vertex AI express mode (now 'Agent Platform in express mode'): card-free 90-day free tier high confidence
Free tier for new Google Cloud users for up to 90 days, within specified quotas, with no billing information required. Rate limits in express free tier: gemini-2.5-pro, gemini-2.5-flash, gemini-2.5-flash-lite and gemini-2.5-flash-image each max 10 requests per minute; gemini-3-pro-image, gemini-3.1-flash-image, gemini-3.1-pro-preview and gemini-3-flash-preview are 'Dynamic' (no fixed number published). Only the listed models are supported; dedicated Live API models (for example gemini-3.8-live) are not. Free-tier data source: Google Drive only. Separate from, and not available through, the Google Cloud Free Program or the $300 trial.
Eligibility
Developers with a @gmail.com Google Account. The 90-day free tier is for NEW Google Cloud users; existing Google Cloud users can sign up for express mode but use their existing billing account on the paid tier. No .edu requirement and no startup cap. Card-free in the free tier.
How to claim
In the Google Cloud console, open Express Mode, sign in with a @gmail.com account and accept the sign-up (APIs are enabled automatically and an API key is issued), then follow the Vertex AI Studio or API express-mode tutorial.
Expiry
90 days from sign-up. The free tier is removed if you are an existing Google Cloud user or after you enable billing (then standard pay-as-you-go limits apply).
Gotchas
Quotas are small (10 RPM on the 2.5 models; 3.x models have no published number). Product renamed: Vertex AI is now part of Gemini Enterprise Agent Platform (official Vertex AI release notes); docs and console names changed. Enabling billing ends the 90-day free tier.
Google Cloud Free Trial: $300 Welcome credit for 90 days high confidence
$300 Welcome credit valid for 90 days from sign-up, spendable on most Google Cloud products including AI APIs, with Free Tier monthly limits available during the trial. Not charged during the trial unless you upgrade. The credit cannot pay Gemini API in AI Studio costs (use the Gemini API free tier or prepay) or third-party partner (MaaS) generative AI models.
Eligibility
Only if you have never been a paying user of Google Cloud, Google Maps Platform or Firebase and have not previously signed up for the Free Trial. A credit card or other payment method valid for the trial period is REQUIRED (not card-free); some countries also require bank-account verification; Google places an authorization hold typically released within a few days to a month. Country availability follows Google's supported-countries list (not fetched this run). No .edu requirement and no startup cap.
How to claim
Go to cloud.google.com/free and click 'Get started for free' (or console.cloud.google.com/freetrial). Sign up, add a payment method and complete verification; a Free Trial billing account preloaded with $300 is created. Upgrade later from the console Welcome page via 'Activate'.
Expiry
90 days from sign-up or until the $300 is spent, whichever comes first. Then the trial billing account closes, with a 30-day grace period before unrecovered resources are permanently deleted. Upgrading ends the trial; leftover credit keeps its 90-day expiry.
Gotchas
Not a card-free offer. Free Tier products require a billing account. The $300 trial does not disqualify you from the Start startup tier (that tier excludes only credits received beyond the free trial, per official wording). Free Tier overage during a trial is paid from the $300 credit, capped at $300 total.
Google Cloud Free Tier (Always Free monthly limits, 20+ products) high confidence
Free usage of select Google Cloud products up to specified monthly limits. Official cloud.google.com/free page: 'free usage of 20+ popular products, including Compute Engine and AI APIs'. Per-product monthly quotas were not verified in this run; earlier third-party quota figures were not confirmed.
Eligibility
A Google Cloud billing account is required to access the Free Tier (official docs). Paid billing accounts pay for any overage; Free Trial accounts draw overage from the $300 credit. No .edu requirement, no startup cap, no region limit captured.
How to claim
Create a billing account (through the Free Trial or a paid signup) and use the products within their monthly limits; monitor usage in the Billing console.
Expiry
Ongoing; no expiry stated for Free Tier monthly limits.
Gotchas
A billing account is needed even for free usage. Exceeding monthly limits on a paid account incurs charges. Exact limits differ by product, so read each product's free-tier page before relying on them.
Google for Startups Cloud Program: Start tier (up to $2,000) high confidence
Up to $2,000 USD in Google Cloud credits, valid for one year. Google Workspace Business Plus free for 12 months for new signups (listed in the official comparison). Official Start-tier description: digital-native startups with a working MVP, a clear business model, and plans to seek venture funding soon.
Eligibility
Founded within the last 24 months; not yet received Google Cloud credits beyond the free trial. The listed criteria do not require a funding round. No .edu requirement. A card requirement is not stated on the captured program page; region not captured. Applications are reviewed and approved against eligibility; approval is not guaranteed.
How to claim
Click 'Apply now' on cloud.google.com/startup/benefits (/startup/apply) and complete the application. The form itself was not captured; third-party guides say it asks for a company website, a company-domain email and billing account details.
Expiry
Credits valid for one year.
Gotchas
Small pool. Credits received beyond the free trial make you ineligible. Scale later requires having received no more than $5,000 in Google Cloud credits.
Google for Startups Cloud Program: Scale tier (up to $200,000, coverage-based) high confidence
Up to $200,000 USD in Google Cloud credits, coverage-based (credit applies only to eligible usage): Year 1 = 100% of eligible usage up to $100,000; Year 2 = 20% of eligible usage up to an additional $100,000. Program credits cover Google's models including Gemini and Gemma. Also Google Workspace Business Plus free for 12 months (new signups) and '$600 monthly credits in Google Maps Platform' (official list; duration text truncated in capture). Official description: VC-funded startups ready to grow and scale.
Eligibility
Funding: raised Pre-Seed or Seed within the last 5 years, or Series A within the last 12 months. Qualifying investment: equity from institutional investors and VCs; SAFEs are eligible; Web3 token raises and blockchain foundation grants are accepted. Private equity, government innovation grants, prize funding, crowdfunding, angel, and friends and family funding do NOT qualify for Scale (evaluated for other tiers). Company: founded within the last five years (official; several third-party sites say 10 years). Operating in stealth is supported upon verification of funding. Prior credits: not more than $5,000 in Google Cloud credits received. No .edu requirement; a card requirement is not stated on the captured page.
How to claim
Apply from the official benefits page (/startup/apply) with funding round details (investor, round, date). Google reviews eligibility and approves at its discretion. Partner and accelerator routes are third-party guidance and unverified.
Expiry
Two-year coverage structure (Year 1 and Year 2 as above); no renewal stated.
Gotchas
Coverage-based, not a lump sum: you are not paid out for unused coverage, and Year 2 drops to 20% coverage. Third-party sources (Rho, Questd, getcloudcredits) give founding-age and tier amounts that differ from the official page; the official page is used here. Angel and friends-and-family money does not count for Scale.
Google for Startups Cloud Program: AI-first track (up to $350,000) high confidence
Up to $350,000 USD in Google Cloud credits for AI startups: Year 1 = 100% of eligible usage up to $250,000; Year 2 = 20% of eligible usage up to an additional $100,000. Also dedicated AI training, resources and experts, and AI webinars and content (official benefits page).
Eligibility
Same funding and company rules as Scale. The official captured text does not define 'AI startup'; third-party guides say the startup must use or plan to use Vertex AI or Gemini as a foundation of its product (unverified). Startup age and funding cap as for Scale.
How to claim
Apply through the same Google for Startups Cloud Program application (/startup/apply); the AI-first tier is a higher tier within the same program and Google assigns it on review.
Expiry
Two-year coverage structure as for Scale.
Gotchas
Credits apply only to eligible usage. Overclaiming AI-first may land you in a lower tier (third-party guidance, unverified).
Google Cloud for Education (students): 200 free Google Skills credits high confidence
200 free Google Skills credits for free online labs, skill badges and courses; credits expire one year after issue. Also free Google Skills Arcade labs, a no-cost preview of Google Cloud Certificates on YouTube, and Developer Student Club chapters. These are learning and lab credits, not Google Cloud billing credits.
Eligibility
Students ('students can request access'). The captured page does not state a .edu email requirement or a student-verification method, nor any startup cap or card requirement. Region not captured.
How to claim
Open cloud.google.com/edu/students, click 'Request credits' (Google Skills), and sign up for the learning-program emails if desired; Developer Student Club chapters are listed on the page.
Expiry
Each credit expires one year after it is issued.
Gotchas
These are training credits for labs and courses, not billing credits for production cloud spend. Do not confuse them with the $300 Free Trial.
Google Cloud Teaching credits: faculty-only course credits high confidence
Google Cloud credits for courses, redeemable from approval until 16 weeks after the course start date and usable for up to 1 year after course start. Up to 3 courses per application. The official form does not state a per-course amount on the captured page (an older Google support article uses a $50 worked example, which is not a grant amount). Credits are for student hands-on learning; not for commercial or personal use and not for course infrastructure; crypto mining prohibited (older support article).
Eligibility
Faculty only: students cannot apply directly but can ask faculty to apply. Available only in the countries listed on the official form (includes the United States and the United Kingdom among others). Older support article: US regionally accredited institutions plus degree-awarding institutions in eligible countries; for-profit institutions not supported. Expected course start date must be within 1 year of the application date. No .edu email rule stated; faculty status at an institution is required.
How to claim
Faculty submit the application at edu.google.com/programs/credits/teaching: personal and institution details, course name, expected start date, course abstract, and how credits will be used. Up to 3 courses. Only the most recent submission is reviewed.
Expiry
Redeem within 16 weeks after course start; credits valid for up to 1 year after course start.
Gotchas
Students cannot apply directly. Approval is discretionary (older support article says Google may change criteria at any time). Credits may not be used for commercial or personal use.
Google Cloud research credits (Academic Research Grants): up to $5,000 high confidence
Up to $5,000 in Google Cloud credits for research (official Cloud for Education listing: 'Apply for up to $5,000 in Google Cloud credits'). Credits provide computing power for research; they have no commercial value and may not be used for commercial purposes.
Eligibility
Faculty, PhD students and postdoctoral researchers at accredited higher-education institutions, and eligible nonprofit research institutions, in approved countries (list not captured). Application requires a link to your profile in the institution's faculty or researcher directory and a link showing candidacy status.

How to claim
Apply at edu.google.com/programs/credits/research with personal information, department, the directory link and candidacy-status link. Only the most recent submission is reviewed.
Expiry
Term and expiry were not captured on the page.
Gotchas

Gemini Academic Program: Gemini API credits and higher rate limits for researchers medium confidence
Qualified academic researchers can apply to receive Gemini API credits and higher rate limits for research projects. Named priority areas include evaluations and benchmarks, scientific discovery (for example rare diseases, materials science, sustainability), and embodiment and interactions. The credit amount is not stated on the captured page.
Eligibility
Qualified academic researchers (faculty, staff and PhD students) in supported countries (list not captured). A research project is required. No startup cap and no .edu-only rule captured.
How to claim
Open the 'Gemini Academic Program' section at ai.google.dev/gemini-api/docs/gemini-for-research and follow its application link (the link itself was not captured in this run).
Expiry
Not stated on the captured page.

Google AI Pro free for 12 months: eligible US college students (consumer plan, not API credit) high confidence
One year of Google AI Pro free (valued at $19.99/month): 4x higher usage limits in Gemini, Gemini Spark, Gemini in Gmail and Google Docs, 5 TB storage, Google Health Premium and more (official Google blog, Aug 19, 2026). Footnote: 'Eligible students in the U.S. only. Offer Terms apply. Redeem until December 31, 2026. Valid form of payment required at sign-up. Unless cancelled earlier, Google AI Pro will automatically charge $19.99/month after the trial ends. Cancel anytime.' This is a consumer subscription and adds no Gemini API quota.
Eligibility
Eligible college students in the United States. Official student-hub text (search snippet, not fully fetched): ages 18+; new users and students whose 2025 AI Pro trial has expired can qualify; eligibility must be verified (method not captured). A .edu address requirement is not stated in the 2026 captured text (the 2025 student offer required a .edu address per The Verge, April 2025). No startup cap.
How to claim
Open gemini.google/students (student hub) and claim 'one year of Google AI Pro'; enter a valid payment method at sign-up and complete student verification when prompted.
Expiry
Free for 12 months; redeem by December 31, 2026; then auto-charged $19.99/month unless cancelled. Cancel anytime.
Gotchas
A payment method IS required even though the year is free, and it auto-renews at $19.99/month after the year. A Romania-locale capture of gemini.google/students showed a different offer (Google AI Plus, 26.99 RON/month after trial), so offers vary by market.
Google AI Plus free for 12 months: eligible students outside the US (consumer plan) high confidence
One year of Google AI Plus free: 2x higher usage limits in Gemini, 400 GB storage, Gemini Omni access (official blog, Aug 19, 2026). Footnote: offered to 'eligible students in over 140 markets where Google AI Plus is available, except for in the U.S., Bolivia, Albania, Canada, Macau, Hong Kong, and Tunisia'. Consumer subscription; not API credits.
Eligibility
Eligible college students outside the U.S. in the listed markets (age and .edu requirement not captured). No startup cap.
How to claim
Claim via gemini.google/students; a valid payment method is required at sign-up.
Expiry
Free for 12 months; redeem-by date is in December 2026 (exact day cut off in capture; the Romania-locale page says 31 Dec 2026). After the trial, $4.99/month or the local-currency equivalent is charged automatically unless cancelled.
Gemini for Education: free for accredited institutions (institution-level) medium confidence
Institutions can get Gemini for Education and NotebookLM free of charge by signing up for Google for Education, even if they use another productivity suite; gives default access to premium models, enterprise data protection and admin-managed access, included in Workspace for Education editions at no charge (official page). Google blog (Sep 8, 2025, search snippet): all accredited higher-education institutions can access Gemini for Education with data protections free of charge; more than 1,000 US institutions had integrated it, reaching over 10 million students.
Eligibility
Accredited higher-education institutions (institution-level, admin-managed). Individual students do not sign up on their own through this route, per the captured text. No .edu email rule stated; an institutional account is required.
How to claim
An institution admin requests an advisory session or signs up for Google for Education (edu.google.com), then turns on Gemini for Education in the Admin console.
Expiry
Not stated. The official page says higher limits than consumer tiers are coming ('soon with significantly higher limits'), which implies paid tiers for heavier use.
Gotchas
Institution-managed rather than individual. Higher limits will be a paid option. Official page says data is not used to train AI models.
Google AI for Education Accelerator: free AI training and Career Certificates (US college students) medium confidence
Free AI training and Google Career Certificates for every college student in America, part of Google's AI education commitment; over 100 colleges and universities had signed up at announcement (Google blog, Aug 6, 2025, search snippet and partial fetch).
Eligibility
US college students, through participating institutions.
How to claim
Access through a participating institution or through Google Career Certificates; details at the blog link (full page not fetched in this run).
Expiry
Not stated.
Gotchas
Training and certificates, not cloud or API credits. Availability depends on institution participation.
(1) Gemini 2.5 Flash Image (gemini-2.5-flash-image) is deprecated and shuts down October 2, 2026 per the official pricing page; migrate to Gemini 3.1 Flash Image or 3.1 Flash Lite Image. It was not on the free tier. (2) Third-party guides (apiyi, findskill, April and May 2026) say that from April 1, 2026 Pro models were removed from the free tier, mandatory spending caps applied, and prepaid billing applied to new accounts; and that free-tier quotas were cut 50 to 80 percent in December 2025. The official pricing page captured 2026-10-22 still lists Gemini 2.5 Pro as Free of charge and Gemini 3.1 Pro Preview as not available on free, so the Pro-removal claim is only partly consistent with official data. The spend-cap idea matches the official rate-limit table's billing tier caps, but those caps are for paid tiers. (3) Vertex AI was folded into Gemini Enterprise Agent Platform (official Vertex AI release notes); express-mode docs now use 'Agent Platform' naming. (4) The 2025 US student offer (Google AI Premium / AI Pro, .edu address required per The Verge, April 2025; sign-up deadline extended to October 6, 2025 per the August 6, 2025 Google blog) has expired. The 2026 US offer redeems until December 31, 2026. (5) Startup tier terms differ across third-party sites (Scale founding age 10 years vs official five years; AI-first Year 1 amounts). The official cloud.google.com/startup/benefits page was used throughout. (6) Unverified: a search snippet attributed to a Google AI Developers Forum thread said the Gemini API would stop accepting unrestricted API keys from June 19, 2026. The fetched copy of that thread did not contain this text, so it is unconfirmed; restricting keys to the Gemini API is still advisable. (7) The $300 / 90-day Google Cloud trial and the Start tier $2,000 / 1-year credits match the official pages captured today; no 2025 or 2026 change to them was found. (8) No country list was captured for the Gemini API free tier; the teaching credits, research grants, Gemini Academic Program and Google AI Plus offers each carry their own country lists. (9) No free offer was found that is specifically labeled as a Gemini API startup credit; startup credits can be spent on Gemini through the Cloud program.
