Meta Perception Language Model checkpoint for detailed image and video understanding
facebook/Perception-LM-3Bmixpeek://image_extractor@v1/facebook_perception_lm_3b_v1Overview
Perception-LM-3B is part of Meta's PerceptionLM release for open, reproducible visual understanding research. The linked paper describes a transparent Perception Language Model stack for detailed image and video understanding, including human-labeled and synthetic data and a PLM-VideoBench evaluation for temporal perception.
On Mixpeek, Perception-LM-3B is useful when teams want a research-friendly VLM for building searchable descriptions of images and video clips. Its license is research-only, so it should be treated as an evaluation and prototyping model rather than a default commercial production choice.
Architecture
Autoregressive vision-language model from the PerceptionLM family. The model combines a Perception Encoder visual backbone with a language decoder and is released in 1B, 3B, and 8B scales for detailed visual understanding experiments.
Mixpeek SDK Integration
// No extractor parameter takes a Hugging Face model id (checked against
// GET /v1/discovery/extractors, which returns 13), so Perception-LM-3B 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.

// Managed alternative, if this exact model is not the requirement:

// (3072-d) over a bucket, with no inference of your own.Capabilities
- Detailed image and video understanding
- Visual question answering over frames and clips
- Temporal video perception research via PLM-VideoBench
- Transparent data and training recipe for reproducible VLM evaluation
- Useful baseline for comparing closed and open visual reasoning models
