Did you use SWE agents?
If so, which agent and model are your favourites?
I found that GPT 5.2 Codex is much better than Claude Opus 4.5, but they work quite well together in turns.

Due to the region I’m in, most of those SWE agents aren’t available where I live.
I did try GitHub Copilot in VS Code a long time ago (GPT / Claude etc). It was pretty dumb — bad suggestions, no real understanding of context. I ended up disabling Copilot completely.
I see.
Yes, at this moment I can recommend only GPT 5.2 (if you use Copilot), or Claude Opus 4.5, as all other models are pretty dumb, I’d say.
I personally use GPT 5.2 Codex xhigh (via Codex CLI) and Claude Code (with Claude Opus 4.5) as my backup, as GPT 5.2 shows the best results for me.
But I am paying quite a lot for ChatGPT Pro and Claude Max 100 subscriptions, so I can work in parallel on multiple big projects, where GPT and Claude recheck each other.

I’ve been using the new Gemini 3 with Crystal, but I’m mostly back and forth chat with it as I need to explore fixes or new features. I’m not letting it use an agent since I don’t want to deal with token exhaustion. For sure is a lot better than 2.5. Only been running into a few things it keeps wanting to do. Though it sucks on macros, but I would expect that.
I will tell you a truth: I built my LLM protocol, that helps models with proper reasoning, because I was tired of Gemini sycophancy and BS. It helped a little to Gemini, but surprisingly it was much better for Claude Opus, but GPT was the best achiever.
I am having a lot of fun with GLM from z.ai and it’s super cheap.

I am building my own SWE agent, and I use Grok 4.1 Fast reasoning that is also super cheap ($0.20/$0.05/$0.50), but quite powerful.
