DeepSeek-V4.1-Flash
DeepSeek-V4.1-Flash is a released multimodal Mixture-of-Experts (MoE) causal encoder-decoder model (552B backbone parameters) that natively processes images and text and generates text autoregressively. The release includes downloadable weights, inference instructions, evaluation artifacts, and tooling for prompt encoding and reproducing agentic benchmarks on Hugging Face.
What it does
A person can use it for long-context reasoning, image-and-text tasks, and agentic coding or automation workflows.
