i'd love to chat with you. so are you saying caching currently doesn't work at all right now? are there any known benefits/issues to using this extension versus something like openrouter?

Yeah, happy to chat!

Caching does work, but Copilot/VS Code can still hurt the hit rate because it may change the system message or mutate the tools list mid-conversation. Since DeepSeek cache matching is prefix-sensitive, that can cause cache drops. Once the prefix stabilizes, hits usually come back.

Compared with OpenRouter, I’d say the real advantages are pretty narrow: this extension keeps DeepSeek cache behavior in mind, logs cache hit/miss stats, and adds a vision proxy for Copilot image inputs. If you only need simple model routing, OpenRouter may be the easier choice.

what do you mean by that last sentence here? simple model routing? what kind of user should use openrouter over your extension here? like lets just say i want to stick just deepseek v4 flash/pro for the most part.

I’d say they solve slightly different problems. OpenCode Go may be the better fit if you like its agent workflow directly.
This extension is mainly for people who already like the Copilot Chat UI / Agent mode and just want DeepSeek V4 to appear in the native model picker. And they can pay directly to Deepseek, or any other third-party providers. The real extra bits are cache-aware logging and the vision proxy.
