deepseek-ai/DeepSeek-V4.1-Flash
deepseek-ai/DeepSeek-V4.1-Flash is a deepseek-ai record on this register. The Hugging Face model API lists the pipeline tag as image-text-to-text. The safetensors index gives an exact parameter count of 763,205,315,794. Architectural context length (max_position_embeddings) is 1,048,576. The listed licence is mit. The Hub repository was created on 10 Sept 2026, which is the release date this register uses.
Primary source: the Hugging Face model card for deepseek-ai/DeepSeek-V4.1-Flash. Fields below come from that card, the Hub model API, and the repository’s own config.json when those files exist. A field we cannot source is omitted rather than guessed.
