Gemini 3.1 Pro

Shared this in the other Gemini Pro 3.1 thread (https://news.ycombinator.com/item?id=47074735) but wanted to share it here as well.

I just tested the "generate an SVG of a pelican riding a bicycle" prompt and this is what I got: https://codepen.io/takoid/pen/wBWLOKj

The model thought for over 5 minutes to produce this. It's not quite photorealistic (some parts are definitely "off"), but this is definitely a significant leap in complexity.

I've been A/B testing the big three (GPT-5, Claude Opus 4, Gemini 3.1) on a real codebase migration this week.

Quick take: Gemini 3.1 Pro's long context is genuinely better now — I fed it a 200k token codebase and it could reference files from the beginning without losing track. That was a real problem in 3.0.

For pure code generation though, Claude still edges it out on following complex multi-step instructions. Gemini tends to take shortcuts when the task has more than ~5 constraints.

The exciting thing is how close they all are. Competition is working exactly as it should.

Anyone know if this is available in the Gemini CLI with a subscription (not api key)? Still seeing only Gemini 3 pro preview
