Latest change

A Sep 12 technical deep dive details the design behind those claims: a 763B-parameter causal encoder-decoder split (8B encoder, 16B decoder) with native vision support.

Earlier contextThe story so far

DeepSeek opened a two-day limited beta for V4.1-Flash on Sep 8, built on a new natively multimodal architecture. Two days later DeepSeek claimed the redesign cuts agentic-task costs by 80%.

What to watch — open questions

  • Does the 80% agentic-cost reduction hold up under independent benchmarking, or is it DeepSeek's own figure?
  • Does the encoder-decoder split require changes to how existing serving stacks (vLLM, SGLang) deploy the model?
