General

Body

The current Copilot model context window is only 128k, which is far from sufficient for scenarios requiring cross-file operations, long-term conversations, or agent-based workflows, impacting the correctness and efficiency of code review, refactoring, and complex tasks.

Impact of the issue:

Multi-file/multi-step agent tasks frequently exceed the context limit;
Automated modifications, dependency analysis, and overall understanding capabilities for large codebases are limited;

Suggested solutions:
Provide optional larger context window tiers (e.g., 200k tokens) for Pro/Pro+ users;
Support consuming higher "advanced request multipliers" or billing multipliers per request or usage to 换取 longer context;
Or provide on-demand upgrade dynamic strategies (e.g., temporarily increasing context limits within a single session/request and billing accordingly).

Expected Benefits:
Significantly improve Copilot's usability and accuracy in agent-based workflows, refactoring, code review, and large-scale project automation scenarios;

Great post @gnahz77 . This is desperately needed.

Does anyone ever actually reply besides the bot? I don't understand why there are no administrators or product team members ever responding. Is that just how it is here? The tool is amazing but only for about 5 minutes at a time before it loses context and acts like it has never met you before.

I'm paying for Github Copilot Pro Plus subscription, and context is 128k approx (200k for some models). Now, Anthropic is offering 1 M context, Gemini already supports 1M, and OpenAI Codex-max supports 400k context. I think I really need more context, or I need to consider switching to another provider, simple as that.

Please github, let us know about the route map and improvements over GitHub Copilot capabilities.
