# Gemini 2.5 Pro API Rate Limits, Pricing & Performance (July 2026)

- Tool: AI API Limits & Performance Matrix
- Last updated: July 2026

## TL;DR

Gemini 2.5 Pro is Google's current flagship API with 1M+ context. It is paid-only since April 1, 2026 — no free tier. Pricing was raised on July 2, 2026: $1.25 input / $10.00 output per MTok (≤200K). The critical budget trap: prompts over 200K tokens cost $2.50/$15.00 for the ENTIRE request. RPM/TPM quotas are project-specific, not published. Context cache reads cost ~$0.125/MTok.

## Frequently asked questions

### What are the rate limits for Gemini 2.5 Pro?

Google does not publish stable RPM or TPM numbers for Gemini 2.5 Pro. Your active quota is project-specific and shown in the AI Studio dashboard. To increase limits, go to Google Cloud Console → IAM & Admin → Quotas → Generative Language API and request an increase (typically 1–5 business days).

### How much does Gemini 2.5 Pro cost?

As of July 2, 2026 (when prices were raised): $1.25 per million input tokens and $10.00 per million output tokens for requests under 200K tokens. Requests over 200K tokens are priced at $2.50/$15.00 per MTok — and the surcharge applies to the entire prompt. Context cache reads cost ~$0.125/MTok. A 50% batch discount is available for async workloads.

### Is Gemini 2.5 Pro free?

No. Gemini 2.5 Pro has been paid-only since April 1, 2026. There is no free tier. If you need a free tier, use Gemini 2.5 Flash, which has approximately 1,500 requests/day free (not guaranteed — shown per project in AI Studio).

### What is the 200K token surcharge and how do I avoid it?

When a single request has more than 200K tokens in the prompt, both input and output pricing switch to the long-context rate ($2.50/$15.00 per MTok) for the ENTIRE request — not just the tokens above 200K. To avoid it: count tokens before each call, truncate or chunk documents, and use context caching for repeated prefixes. One token over the threshold can nearly double the cost of a request.

### How do I fix a 429 RESOURCE_EXHAUSTED error on Gemini 2.5 Pro?

Add exponential backoff to your retry logic (start 1s, double each attempt, cap 64s, add jitter). Check your active quota in AI Studio. For sustained rate limit issues, request a quota increase in Google Cloud Console → IAM & Admin → Quotas. If you're hitting limits because of free-tier, add billing — 2.5 Pro is paid-only.

### Gemini 2.5 Pro vs Gemini 2.5 Flash — which should I use?

Use Flash ($0.30/$2.50 per MTok) for high-volume, cost-sensitive, or latency-sensitive workloads. Flash has the same 1M context window, no long-context surcharge, and a free tier. Use Pro ($1.25/$10.00) only when tasks genuinely require its higher reasoning capability. Routing Pro-quality-required requests to Pro and everything else to Flash is the most cost-effective architecture.

### How do I increase Gemini 2.5 Pro quota limits?

Go to Google Cloud Console → IAM & Admin → Quotas → search for Generative Language API → find the Gemini 2.5 Pro quota → click Request increase. Approvals typically take 1–5 business days. For enterprise-grade capacity, contact Google Cloud Sales or use Vertex AI.

### Can Gemini 2.5 Pro process video and audio?

Yes. Gemini 2.5 Pro accepts text, image, audio, and video as input, producing text output. This is a key advantage over Claude 4 Sonnet (text/image only) and most GPT models with limited audio/video support. Input tokens for non-text modalities are charged at the standard per-token rates.
