Man, I'm not so sure if I'd use something like this because the way I prompt already changes based upon what model I am using. I'm not convinced it would route to the right model based on my diction or whatever.
Yeah that's a really interesting point, tbh I think the more relevant variable here is the harness you're using rather than the specific model? i.e. GPT 5.5 in the Claude harness behaves a lot more like Claude than Codex if that makes sense.
Hard to quantify this ofc but that's what I've felt vibes wise from using this for the last month.
I have the same general feeling as well. Like you, I can’t prove it’s not just personal feeling - but e.x. Opus via Copilot CLI behaves entirely different than Opus via Claude Code, which behaves differently than Opus via OpenCode or Pi.
I have the same feeling. I've been trying Claude Code directly ever since Copilot nerfed their request-based system, and Opus just seems to perform "better" in Claude Code.
It's also possible that it's the 1m context versus the 200k context (Copilot's limit) doing some of the work here.
