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: - Base architecture: XLM-RoBERTa large - Embedding size: 1024 ## Quantization This package stores selected 2D weight tensors using a R.E.V.I.S. MLX-native Q6 format: - Quantization type: `mlx-native-affine` - Bits: `6` - Group size: `64` - Mode: `affine` - Stored tensors: packed `.qweight` plus `.scales` and `.biases` - Expected linear path: `mx.quantized_matmul(..., qweight, scales=scales, biases=biases, group_size=64, bits=6, mode="affine")` - Expected embedding lookup path: gather the packed rows first, then `mx.dequantize(..., scales=scales, biases=biases, group_size=64, bits=6, mode="affine")` Typical tensor layout: ```text encoder.layer.0.attention.self.query.weight.qweight encoder.layer.0.attention.self.query.weight.scales encoder.layer.0.attention.self.query.weight.biases ``` The `.qweight` tensors are MLX packed integer tensors, not plain row-major integer arrays. 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 than Q8 while preserving very similar keyword-retrieval behavior in R.E.V.I.S. Runtimes should read `quantization.json` for the exact tensor names and quantization parameters before loading the weights. ## 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. If you are interested in pushing the absolute limits of local AI and open-weight models, check out our project. - Official Website: - Watch the 13-min Raw Demo (Multi-node Dynamic RAG): - Follow our updates on X: ## 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. ## Files Recommended repository files: ```text README.md LICENSE NOTICE weights.00.safetensors config.json tokenizer.json tokenizer_config.json special_tokens_map.json quantization.json ``` ## License This repository redistributes a quantized package derived from `intfloat/multilingual-e5-large`, which is released under the **MIT License**.
