MetaEncoder-30B is a multimodal embedding model from Meta AI, posted on Hugging Face on 2026-11-12. It maps text, images and video into 6,656-dimension L2-normalized vectors for retrieval, and the same vectors answer yes/no, multiple-choice and scored questions about a scene. It is built by contrastively fine-tuning the Muse-Glimmer-30B decoder, ships in BF16 Safetensors and fits on a single 80 GB GPU with transformers 5.15 or later. The model card carries no license text.
A situational 30B-parameter dense embedding model from Meta. Treat the modality benchmarks above as the leading indicator of fit — composite scoring across modalities is still maturing. Newly released, so production-readiness is still being shaken out.

MetaEncoder-30B is a bi-encoder with a natural language interface: a task and each candidate are written in free-form text, with images and video as side information, and matching is an inner product over cached representations. The MetaEncoder wrapper exposes encode, retrieve, decide and calibrate calls. Decisions return a value, probabilities and a confidence score, with a default softmax temperature of 0.02. Images keep native resolution snapped to a 28-pixel grid up to 4,096 merged tokens, and video clips longer than 8 frames are sampled down to 8 frames. Training sequences were capped at 16,384 tokens, and nothing is truncated at inference.
