DeepSeek V4.1 Flash reportedly bakes prefill/decode disaggregation into the model weights
altryne · x · 2026-09-11
- Per Chris Alexiuk (@llmwizard), DeepSeek V4.1 Flash has baked disaggregation into the model itself: the prefill/decode split is reflected in the weights rather than only in the serving stack.
- Prefill and decode are different computational jobs, and the industry typically separates them at the inference infrastructure level; embedding that split into the weights would be a highly unusual design. Third-party report, unconfirmed.
