Google Gemini Free Tier Overview

Introduction

Google exposes the Gemini family through AI Studio with a free API tier that includes per-minute and daily rate limits. The free tier supports text, vision, and multimodal inputs, making it the go-to entry point for personal projects and learning. As of 2026-08-22, Gemini officially joined the APIShare free channel pool: 10 chat models verified, all entering the main ranking.

Models and Quotas

Endpoint: https://generativelanguage.googleapis.com/v1beta/models/{model}:generateContent. The 10 models currently in the pool:

Model Input cap Max output Positioning
gemini-3.7-flash 1M 64K Current flagship, complex tasks
gemini-3.6-flash 1M 64K Google's recommended stable pick for new projects
gemini-3.5-flash 1M 64K Stable generation
gemini-3-flash-preview 1M 64K Preview generation
gemini-3.1-flash-lite 1M 64K Lightweight, low-cost pipelines
gemini-3.1-flash-lite-preview 1M 64K Lightweight (preview)
gemini-flash-latest 1M 64K Alias that tracks the newest Flash
gemini-flash-lite-latest 1M 64K Alias that tracks the newest Lite
gemma-4-31b-it 256K — Open-source workhorse
gemma-4-26b-a4b-it 256K — Open-source lightweight

The Gemini Flash family ships a uniform 1M input / 64K output envelope; the gemma-4 twins run a 256K context. Free-tier throughput is roughly 15 RPM / 1500 RPD (check the console); back off with a token bucket on 429s.

ℹ️ Specialist capabilities (image generation, TTS, realtime voice, embeddings, video/music) carry zero free-tier quota and are not in the pool — use the paid tier or watch for future intake notices.

Call Example

from google import genai

client = genai.Client(api_key="AIza...")
resp = client.models.generate_content(
    model="gemini-3.6-flash",
    contents="Explain the attention mechanism in transformers.",
)
print(resp.text)

Caveats

Three constraints matter in practice. First, free-tier request data may be used for model improvement — the paid tier opts out, so sensitive workloads must upgrade. Second, model versions on the free tier can lag the paid tier by a release cycle. Third, regional availability varies — confirm in the docs before building region-specific logic. The 1M context window is excellent for long-document Q&A and repo-scale analysis, but the 1500 RPD cap means pacing batch jobs carefully. Handle prompt_feedback.block_reason explicitly: treating a safety-blocked response as an empty success silently corrupts downstream logic. Finally, never use the gemini-2.5-* family (they return 404 for new users' API keys); older gemini-1.5-* and gemini-2.0-flash have also left the free-tier list — migrate existing code to gemini-3.5-flash or newer.
