# mavis-ai/Multilingual-e5-large-Q8
This repository contains an 8-bit quantized MLX-compatible distribution of `intfloat/multilingual-e5-large`, prepared for use with **R.E.V.I.S.** as its local semantic embedding model.
The model is intended for local text embedding, semantic recall, RAG retrieval, and multilingual semantic search workflows.
## Important Notice
This repository is hosted primarily as a dedicated download source for the R.E.V.I.S. application ecosystem. You are free to download and use this model package for your own local embedding or MLX workflows, subject to the MIT License and the attribution notices included in this repository.
This package is **not** a new embedding model and has **not** been fine-tuned. It is a quantized redistribution of `intfloat/multilingual-e5-large`.
For the original model card, training details, intended usage, and evaluation information, refer to the official upstream model:
- Original model: <https://huggingface.co/intfloat/multilingual-e5-large>
- Base architecture: XLM-RoBERTa large
- Embedding size: 1024
## Quantization
This package stores selected 2D weight tensors using a R.E.V.I.S. Q8 format:
- Quantization type: symmetric per-row int8
- Scale format: per-row scale tensor
- Expected dequantization: `weight = qweight.astype(float16) * scale[:, None].astype(float16)`
Typical tensor layout:
```text
encoder.layer.0.attention.self.query.weight.qweight
encoder.layer.0.attention.self.query.weight.scale
```
Non-quantized tensors, such as LayerNorm parameters, bias tensors, and other small metadata tensors, are preserved in their original floating-point representation.
This format is optimized for smaller download and storage size. In the current R.E.V.I.S. runtime, q8 tensors may be dequantized to floating point at load time for compatibility with the existing embedding forward path.
## Optimized for R.E.V.I.S. (Local Cognitive OS)
We host this model package to serve as the local semantic embedding engine for **R.E.V.I.S.**
**R.E.V.I.S.** is a 100% local Cognitive OS for Multi-Agentic AI. It transforms your Mac devices into a distributed Agentic Swarm via zero-config Wi-Fi clustering, allowing you to run heavy AI workloads—like recursive web research, dynamic RAG generation, and multi-step logic—without killing single-machine performance.

## Usage Notes
For retrieval-style tasks, E5 models typically use different text prefixes for queries and passages. R.E.V.I.S. applies its own canonical query and passage formatting internally.
If you use this package outside R.E.V.I.S., refer to the upstream E5 instructions for recommended prompt prefixes and pooling behavior.
