What's the best AI model for coding?

by•

New AI models pop up every week. Some developer tools like , , and let you choose between different models, while more opinionated products like and default to 1 model.

Curious what the community recommends for coding tasks? Any preferences?

Claude Opus 4.5 (Thinking) 32K ?

Anthropic has a huge head start with their models. But to be precise, it's the models coupled with Claude Code that allow us to enter a new era and give superpowers to developers.
The only downside to all this remains the price of tokens which are starting to become more and more uncontrollable.

I work a lot on this issue, particularly on token compression technology, which will allow us to better reduce, control, and make the ecosystem a bit more frugal... at least I hope so.

 - could help us reduce the CC bill?

 Absolutely! That's what we do. is a Token Compression technology which can save up to 50% of the token bill. And it works with Claude Code pro/max plan as well

Why have you missed the Opus 4.5?

good point - can't edit the poll! +1

From left field, and after a lot of experimentation, I'm currently going to swear by; cosine.sh hooked with cubic.dev to catch any bugs.

 oooooh good point. I forgot to include Genie 2 by in the list. heard great things about (currently using and according to their docs). great combo!

Sometime Grok for a good outline and Sonnet 4.5 for the detail work using Cursor as the IDE

 any experiences with Composer 1?

For me personally: gpt-5.2-codex all the way. Dry as a brick, but the results speak for themselves.

I prefer Opus 4.5 more than Sonnet. Even though Opus maybe be a tad bit slower but it provides better reasoning and context understanding. I personally feel Opus provides a balance in that sense.

family (Sonnet, Opus) is definitely leading the way

Hands down Sonnet 4.5 for me. Doing okay with Gemini 3 (Flash), but I don't feel GPT 5.2 and I will become a team. It's just it feels like Sonnet really knows e.g. TS in real detail. But then maybe I just like how the others behave in VSCode....

Where is Opus?

I don't think there are big gaps between those models; it depends on the problems I am trying to solve. I usually start with Sonnet 4.5 and try others if it fails to resolve my problem. In cursor, they allow you to run multiple models in parallel, actually

 have you experimented with Composer 1? any feedback/thoughts?

 No, actually. But will try and keep u posted ;)

 looking forward to your thoughts!
