Yes — the Gemini API still has a genuinely free tier in October 2026, but it's tighter than the one people remember from 2024–2025. The Flash-class models keep free access with per-project rate limits, Pro-class models are paid (with promotional pricing through December 31, 2026), and Google has made limits explicitly per-project rather than per-key.
Here's exactly how it works now, and how to get a key in about two minutes.
Last verified: October 1, 2026. Google adjusts these quotas frequently — the AI Studio rate-limit dashboard always shows your live limits.
What's still free
- The Flash/Flash-Lite lineup. Gemini 3.8 Flash (the newest), plus the 3.7/3.6/3.5 Flash tiers and the Flash-Lite models, remain available at $0 with rate limits.
- No credit card. You create a key in Google AI Studio with just a Google account.
- Rate limits per project, in three dimensions: requests per minute (RPM), tokens per minute (TPM) and requests per day (RPD). Exceeding any of the three triggers a 429 error; daily quotas reset at midnight Pacific.
What changed in 2026
- Quotas shrank and some models left the free tier. The famously generous legacy limits were reduced — Google confirmed lowering or removing free-tier access for a batch of models, and Pro-class models are no longer meaningfully free.
- Limits are per project, not per key. Creating extra API keys inside the same project adds nothing. The workaround is separate Google Cloud projects — within Google's fair-use terms.
- Spend-based limits joined RPM/TPM. Paid tiers get rolling 10-minute spend caps (200 at Tier 3) to prevent surprise bills.
- Promotional paid pricing runs through December 31, 2026. Google published promo rates for paid-tier usage — for example, Gemini 3.5-class input at 3.75 — check the official pricing page for your exact model.

How to get a Gemini API key (2 minutes)
- Sign in at Google AI Studio with a Google account.
- Accept the terms of service.
- Click Create API key — optionally scoped to a Google Cloud project (scoping matters: your project is your quota bucket).
- Copy the
AIza…key and paste it into your tool of choice.
In SynthHires, paste it under Google Gemini in /space/models — it's encrypted in your browser with AES-256-GCM and never leaves your device. The whole Gemini catalog then lights up in the model picker.
Is the free tier enough for real work?
For development, learning, prototypes and light personal automation — comfortably. The free tier is a prototyping tier by design: you'll hit daily caps on any batch workload. When you outgrow it, adding a billing account promotes the project to Tier 1 instantly (with a $250 billing cap), and higher tiers unlock with cumulative spend.
FAQ
Is the Gemini API free in 2026?
Yes — the Flash/Flash-Lite model lineup keeps a free tier with RPM/TPM/RPD limits per project, no credit card required. Pro-class models require billing, though promotional paid pricing runs through December 31, 2026.
Why did my Gemini rate limits get worse?
Google reduced free-tier quotas during 2026 and moved limits to a per-project basis. Extra keys in the same project don't add quota; a separate project (or upgrading to a paid tier) is what raises your ceiling. Check your live numbers in the AI Studio rate-limit dashboard.
Can I use the Gemini free tier commercially?
Google's terms allow commercial use of API outputs; what the free tier constrains is volume (rate limits), not the license. For sustained production traffic, move to a paid tier — the promotional rates through 2026 make the jump cheaper than usual.
How does Gemini's free tier compare with other providers in 2026?
It remains one of the best free deals alongside Groq's rate-limited free access, Mistral's Experiment plan, Cerebras, Cohere trial keys and OpenRouter's 25+ :free models. Full provider-by-provider breakdown in our free AI API keys guide.
Grab the key, paste it in, and you're running current-generation Gemini models at $0 — see the Get API keys guide for every provider, or the October 2026 price table to plan what happens when you outgrow free.
