i use claude-4-sonnet then gemini-2.5-pro as a fallback

claude-4-sonnet: seems to be the best at tool calling and actually changing the lines

gemini-2.5-pro: solves what sonnet can't solve, but you have to run it a couple of times to get the tool calling mistakes out

claude code is my daily pair programming buddy;

I tried chatGPT, claude, claude code, cursor and ampcode. I sticked to claude code at the end.

Devstral + Openhands is still my workhorse.

Qwen3 coder 30b I've finally sorted and was using it all day with qwen code.

Qwen3 30b thinking is likely still better than coder?

Free gemini 2.5 pro is my backup for the tough problems.

Tomorrow though. LM Studio just released their latest version which greatly improves tool calling with GPT 20b. I'm running it at 120k context and medium reasoning. I'm pretty confident it's about to become to go-to.
