Gemini 3 Pro
Google's flagship multimodal model with a 1M-token context window
Gemini 3 Pro is Google’s flagship model, announced November 18, 2025 as the successor to Gemini 2.5 Pro. It reads and generates across text, image, audio, and video, with a 1 million token input context window and up to 64,000 tokens of output, and it launched with strong claims on math, science, and agentic benchmarks. On release it broke 1500 Elo on the LMArena leaderboard, reaching 1501 and taking the top public ranking, and Google reported it scoring well ahead of rival models on multimodal understanding tests like MMMU-Pro.
Google prices the API at $2.00 per million input tokens and $12.00 per million output tokens for prompts up to 200,000 tokens, doubling beyond that. It’s available through the Gemini app, Google AI Studio, Vertex AI, and the Gemini API, and it underpins Google’s newer agentic tools and coding assistants. Google followed it with Gemini 3.1 Pro in February 2026, which pushed reasoning scores further while keeping the same context window and similar pricing.
