I wonder if it's just going to be a rebranded Reasonix (https://github.com/esengine/DeepSeek-Reasonix) as it's the only harness their docs mention and it seems specially built for deepseek models.
In DeepSeek V4 Pro 0813Have you tried reasonix?

In DSpark: Speculative decoding accelerates LLM inference [pdf]Their blob explains it best, although this is a link to an older version design: https://github.com/esengine/DeepSeek-Reasonix/blob/v1/docs/A...
From my understanding if previous tokens are frozen and guaranteed to be immutable you can leverage that.
In The unbearable cheapness of open weight modelsThis would be a better page to link to https://github.com/esengine/DeepSeek-Reasonix/blob/main/docs...
They explain some of the the reasons why they have a better solution and why they are very opinionated
>Automatic prefix caching activates only when the exact byte prefix of the previous request matches. Most agent loops reorder, rewrite, or inject fresh timestamps each turn — cache hit rate in practice: <20%.
So they optimize on this plus other techniques to improve cache hits, making it cheaper.
In DeepSeek reasonix, DeepSeek native coding agent with high caching and low cost
