On the first try, Kimi K3 just found the source of a bug that Fable 5 hasn't been able to pinpoint in multiple attempts. It's just one anecdote, and I haven't used K3 much yet, but so far it's looking extremely promising.
Update: the subscription limits are pretty brutal. My first impression is that the $100 subscription eats into the quota at a pace similar to the $200 Anthropic subscriptions when using Fable.
But the model itself is amazing. I think I might put this above Opus 4.8.

Very interesting, thanks for sharing! Could you give some details about what kind of software (language or environment) and what kind of bug it was? Was it a single-file bug, like could it fit in one context like a chat window, or were you using an agentic version (Kimi Code) that looked through multiple files and then found a bug that manifested through complex interactions of multiple systems/files?
How do you use kimi for agentic tasks? I'm used to claude code & codex extensions for vs code, but recently switched to codex cli w/ vim keybinds. Does something like that exist for openrouter?
I've been happilly using kimi models via the $10/month opencode-go[1] subscription for a few months now. I also use pi[2], instead of opencode. Their extensions api is nice, though OpenCode's is similar. My personal preference is more minimalism, add extensions when I want them, instead of the kitchen sink approach.
This is entirely for personal use and small projects. I don't have huge needs. I get access to gpt models via my employer for work things. But I'm also using pi with those models.
I don't use Codex CLI myself, but you can configure it to point to OpenRouter instead. OpenRouter has some instructions for Codex CLI and Claude Code here (though they mention Claude Code is not guaranteed to work!):
