Rumor: DeepSeek V4.1 Flash bakes prefill-decode disaggregation into model weights
altryne · x · 2026-09-11
Quoting Chris Alexiuk's analysis: DeepSeek V4.1 Flash reportedly built disaggregation into the model itself. Prefill and decode are different jobs, typically split at the serving layer — the claim is that DeepSeek encoded that split into the weights rather than just the serving stack. Unconfirmed, but an unconventional inference-design move if true.
