## Runs On

What it takes to serve meta-encoder (29.8B parameters): the memory its weights need at each precision, and the cheapest way to rent enough data-center GPUs to hold them.

Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the [SAVRN Index](https://savrn.com/ai-index/pricing/gpus), read Oct 9, 2026.

## Model Card

By AI at Meta, published under apache-2.0, revision 3d0df704aa5b.

### MetaEncoder-30B

Multimodal System One Encoder with a natural language interface for instruction-following encoding: give it a task and a list of candidates, and it scores the candidates by task specification. Both a task and each candidate are expressed in natural language — instructions, queries, questions, state descriptions, criteria — with image and video as side information.

Key features:

- Natural language interface. No rigid schemas. Describe the task and the candidates in free-form text.
- Highly-efficient cacheable representations. Candidates and task are encoded separately by prompt instructions that ground each other.
- Scales to arbitrarily large candidate sets. Matching is an inner product over representations, so an ANN index can serve millions of candidates without re-running the model.

The model is built by contrastively fine-tuning [meta-models/Muse-Glimmer-30B](https://huggingface.co/meta-models/Muse-Glimmer-30B). It is described in the paper [MetaEncoder: Exploring the Limit of Bi-Encoders for Multimodal System One Decision Making with Natural Language Interface](https://arxiv.org/abs/2610.11316).

## Questions About meta-encoder

### How much GPU memory does meta-encoder need?

About 71.5 GB at 16-bit and 17.9 GB at 4-bit: the weights (29.8B parameters) plus a working margin. A long context needs more.

### What is the cheapest GPU to run meta-encoder on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

### Can I use meta-encoder commercially?

Yes. meta-encoder is released under Apache License 2.0. The Apache License 2.0 is a permissive open-source license. It permits commercial use, modification and redistribution. It requires keeping the license and copyright notices and any NOTICE file, stating significant changes, and it includes an express patent grant from contributors.
