Hi! I'm here to help out the maintainers and am going to investigate this context window discrepancy for the Kimi-K2 model. I'll look into why RooCode is showing 63K instead of the 131K context window that OpenRouter advertises.

I've created a pull request to fix this issue: #6760

The fix adds a manual override for the Kimi-K2 model to set its context window to 131K (131072 tokens) instead of the 63K that the OpenRouter API currently returns. This ensures that RooCode users get the full advertised context window for this model.

The solution follows the same pattern used for other model overrides in the codebase (like Claude and Horizon models), and includes a test to verify the override works correctly.

Hi @sourabhv I think it depends on which provider your request is routed to. You can see that different ones here support different context windows: https://openrouter.ai/moonshotai/kimi-k2. If you want to choose one, you can select from the dropdown in your API profile advanced settings. Going to close this for now but reopen if you're still having issues. Thanks!
