Okay, I'm curious.

From the FAQ, I see:

>Can I point it at a self-hosted / private DeepSeek endpoint?

>Yes. Since 0.30 we accept non-standard key prefixes for self-hosted DeepSeek endpoints. Just point `baseUrl` at your internal address — the loop, cache strategy, and tool protocol are unchanged.

But my question is: If I use Reasonix to talk to a deepseek endpoint through openrouter, am I still getting the cache-hit benifits of this agent harness?

Yes*. At least from my limited usage of deepseek-flash for a few billion tokens on openrouter, the cache-hit rate is >95%. And I simply used the claude code harness pointed at the openrouter anthropic compatible endpoint with no fluff.

Did you get proper tool use? Some CC-driven models seem to get a bit off when it comes to MCP usage. For example: I really struggled to get Kimi to use Serena, which I think ended up costing too many tokens.

thank you!

I would wonder that too, I'm only a novice openrouter user, but I do notice it reroutes my same-model requests to different providers.

Maybe users reporting otherwise are just looking at their client reports which wouldn't be able to tell the difference.

Look into Openrouter's provider routing.
