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.

That looks amazing!

But huh, I get... this: https://www.svgviewer.dev/s/1MOs0uyb (on Gemini 3.1 Pro) ... what... is wrong with my Gemini?

I got this : https://www.svgviewer.dev/s/DNq3oGMB

pro with the 20$ subscription , from the gemini.google.com site , initially the request was routed to nano banana,

so I had to change the prompt and had to be very specific about not generating the image directly, here the exact prompt :

"I want the html svg code for that ( not the generated image) , generate an SVG of a pelican riding a bicycle"

Please don't duplicate comments - it makes merging threads a pain!

Letting us know that there's a dupe situation going on is helpful, if you have a minute to email hn@ycombinator.com.

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

Google is known for not giving you an option to give them your money for AI tools. Maybe they will fix this soon.

Is there a way to use Gemini CLI with a $20 plan, like it is with Anthropic or OpenAI CLI agents?

Yes I have the "Google AI Pro" plan from here https://gemini.google/subscriptions/ and you can login to the Gemini CLI with oauth
