In short: no.

Nothing comes close, in my opinion. Sonnet and Opus are still the best models. The Codex variants of the GPT models are also great. I've tried MiniMax, GLM, Qwen and Kimi and for anything even remotely complex these models seriously struggle.

Thank you for the honest answer.

Yes, this is the conclusion I've come to as well. I don't want to continue supporting OpenAI nor Anthropic, but the other models don't seem to be anywhere close yet, despite the hype.

Yes GLM5 and KimiK2.5 are pretty close replacements for sonnet.

What coding harness are you using? What are some example workflows you have used either for? Have you used them only for new/simple projects or for more complicated refactoring or architecture design?
reply
I use OpenCode and have just started using Nanoclaw with ClaudeCode (my coworker has a post coming on this) and sometimes ClaudeCode with Claude Code Router. I do a range of small to complex work with these but I also do drop back in to Claude Opus for some really complex things where I want it to be more autonomous.

Haven't really tried GLM5 much but I've used 4.7 quite a bit and it was pretty far from competing with Sonnet at the time, although I saw claims online to the contrary.
