Gemini 2.5 Pro

by Google

Gemini 2.5 Pro is Google's high-end Gemini 2.5 thinking model, built for complex reasoning across mathematics, STEM, and software development. With a 1M-token context window and an extended reasoning mode, it works through intricate problems step by step, a fit for scientific research, advanced coding, and multi-step agentic workflows. The model accepts multimodal inputs including text, images, audio, video, and PDFs, so it can analyze entire codebases, research papers, and heterogeneous datasets in a single request. It supports function calling, structured outputs, code execution, and grounding with both Google Search and Google Maps. Compare it to Gemini 2.5 Flash for price-sensitive general tasks, or to Gemini 3.1 Pro for the latest generation with improved agentic capability and reasoning performance. Gemini 2.5 Pro remains strong for reasoning-heavy applications where accuracy matters most.

Uptime and availability

Gemini 2.5 Pro runs on a single route through the Opper gateway today, so its availability is that provider's availability.

100%route uptime, last 30 days
Single route, no failover target within this model.

Name a second model in the same request and the gateway tries it on retriable errors, so a busy hour never has to reach your users. Set up a fallback chain.

Measured over the last 30 days from each provider's official status feed via StatusGator. Refreshed hourly. See uptime for every provider Opper monitors.

Data handling per route

Each route hosting Gemini 2.5 Pro has its own privacy posture, residency, and GDPR terms. Postures are maintained by Opper with a last-verification timestamp.

Get started

Call Gemini 2.5 Pro through the Opper gateway with one API key. Let your coding agent set it up, or call it directly β€” Opper is drop-in compatible with the OpenAI, Anthropic, and Google AI SDKs.

Set it up with your agent

Copy this and paste it into a coding agent like Claude Code, Cursor or Codex and it'll wire up Opper for you.

Or call it directly

import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.OPPER_API_KEY,
baseURL: "https://api.opper.ai/v3/compat",
});
const completion = await client.chat.completions.create({
model: "vertexai/gemini-2.5-pro",
messages: [{ role: "user", content: "Hello" }],
});
console.log(completion.choices[0].message.content);
