Why this status
Newly added. Sources are not archived and no value has been traced to one yet — run `npm run enrich`. Modalities from the model card's own pipeline_tag "image-text-to-text" on deepseek-ai/DeepSeek-V4.1-Flash.
What these states mean · How records are judged · Has this record changed?
DeepSeek released DeepSeek-V4.1-Flash, which it describes as the smallest model in a new architecture family, with native multimodal visual understanding and an architecture designed for a higher capability ceiling, faster inference and higher throughput. It is served on the DeepSeek API as deepseek-flash. DeepSeek also retired deepseek-v4-flash-vision-exp on the same day, with its requests now served by this model.

What changed from DeepSeek V4 Flash
Compared with the previous release in this series. A field appears only when both records state a value — where one does not, it is listed as uncomparable rather than dropped, because a gap in our research is not a finding about the model.
