Short-video VLM with temporal precision via 3D positional encoding
Kwai-Keye/Keye-VL-8B-Previewmixpeek://video_extractor@v1/kwai_keye_vl_8b_v1Overview
Keye-VL is a multimodal VLM specifically engineered for short-form video understanding while maintaining general vision-language abilities. Built by Kuaishou (operator of one of the world's largest short-video platforms), it uses 3D RoPE for unified text/image/video processing with one-to-one correspondence between position encoding and absolute time.
Trained on 600B+ tokens with video emphasis, Keye-VL excels at understanding the dominant content format of the modern internet: short clips.
Architecture
8B parameter model built on Qwen3-8B + SigLIP vision encoder. Uses 3D RoPE (Rotary Position Embedding) for unified spatial-temporal encoding, enabling precise temporal grounding in video content.

// No extractor parameter takes a Hugging Face model id (checked against
// GET /v1/discovery/extractors, which returns 13), so Keye-VL-8B-Preview runs
// on your side and the output is upserted through POST
// /v1/namespaces/{namespace_id}/documents/upsert. On Enterprise the other
// path is to upload the weights instead: POST /v1/namespaces/{id}/models
// accepts the huggingface format and a custom plugin loads them.
