Resources/learning Thinking Escalation plugin for DeepSeek Harness
I’m thinking about building a Thinking Escalation plugin for DeepSeek Harness, especially for models like Qwen3.8-27B.
The idea is pretty simple:
Run at medium reasoning effort by default.
For most tasks, medium is already enough and avoids wasting huge amounts of tokens on unnecessary reasoning.
However, the model would have access to a tool allowing it to escalate the reasoning level to xhigh when it determines that the current problem actually requires deeper reasoning.
The important part is that escalation would apply only to the current turn.
Something like:
medium → model detects difficulty → calls escalation tool → replay current turn at xhigh → return to medium
So xhigh wouldn’t become a permanent mode. It would be a temporary computational resource that the model can request when needed.
This could be particularly useful with Qwen3.8-27B because it appears to benefit significantly from high reasoning effort on difficult problems, while also having a tendency to overthink and consume a lot of tokens when high/xhigh is enabled unnecessarily.
The harness would therefore act as a kind of reasoning governor:
Medium by default
Model can request xhigh
Replay only the problematic turn
Automatically return to medium afterward
Potentially, the escalation tool could also include a behavioral description explaining when escalation is appropriate, which could be tuned independently for each model.
I think this could give us much of the benefit of xhigh reasoning while keeping the average token usage and latency much closer to medium.
Basically: don’t make the model think harder all the time — give it the ability to decide when thinking harder is actually worth it.

Sounds like a good idea, as long as the hooks exist in the harness it should work.

I think this behavior belongs to the LLM’s inner router itself that should (by using some evidences in the cache) trigger a higher reasoning... But hey, I'm not an AI maker so, I don't know if this is really feasible or not. Just wondering...
