MiniMax-M3-speedy-colibri-nvfp4

NVFP4 container for colibrì, a Rust MoE inference engine for single-box streaming-expert inference.

This repository exists so the model can be downloaded and run directly, with no conversion step. Converting the upstream checkpoint requires holding the source and the container on disk at the same time; this container is the finished artefact.

• Upstream: nvidia/MiniMax-M3-NVFP4
• Base model: MiniMaxAI/MiniMax-M3
• Architecture: 60 layers, GQA (64Q/4KV, partial rope 64); 128 experts top-4, sigmoid+bias router
• Expert format: NVFP4

What was changed

Weights were repacked into colibrì's container layout. Routed experts are NVFP4 as published upstream; the container repacks them into coalesced per-expert spans for streaming. No fine-tuning, distillation, or other modification of model behaviour was performed.
