Name: DeepSeek V4.1 Flash 1017
Author: DeepSeek

DeepSeek V4.1 Flash 1017 — the October update to V4.1 Flash: same 552B-backbone, 16B-active multimodal MoE with clear gains on coding, agentic and visual tasks and shorter outputs. Weighs 763B on disk for the same reason as V4.1 Flash: Engram lookup tables plus a speculative-decoding draft module.
