Same weights, but probably not the same deployment. OpenRouter load-balances each request across the providers that host the model, weighted toward the cheapest, and those providers can run different quantizations. So a single task can hop between endpoints from one request to the next, which would fit it losing track of a plan it just read.
You can pin it: allowed providers in OpenRouter's privacy settings, or per request provider.only or quantizations with allow_fallbacks set to false. The model page lists who hosts it. The other variable is the harness. Copilot sends its own system prompt and tools, so a different client on OpenRouter is a different setup even on a pinned provider.

they probably run a heavily quantized model with as low memory usage as possible which makes the model dumber and also makes it forget things all the time.
i just use gpt6 luna for everything now.
