About Gemini 3.1 Pro
Gemini 3.1 Pro takes more kinds of input than any other model here: text, images, audio, video and PDFs, in a context of about a million tokens. Hand it an hour of meeting recording or a long scanned report and ask questions across all of it. It is a strong reasoner too — 77.1% on ARC-AGI-2 at launch, more than double Gemini 3 Pro — and scored 80.6% on SWE-Bench Verified.
Google still labels it a preview, eight months on, which means it can change under you. Its knowledge stops in January 2025, the oldest of the frontier models here, and the newer Gemini Flash releases now beat it on some agent tests.
What is Gemini 3.1 Pro good for?
- Questions across video, audio and long PDFs at once.
- Abstract reasoning and science problems.
- Understanding a large codebase in one pass.
Where to be careful
- Still a preview model, and Google warns it may change.
- Its knowledge stops at January 2025.
- Answers are capped at about 65K tokens, half what Claude and GPT-6 can write.
