MiniMax-M3-EAGLE3-GQA

Model Overview

Inferact/MiniMax-M3-EAGLE3-GQA is a grouped-query-attention (GQA) EAGLE3 draft model for accelerating inference of MiniMax-M3, served with vLLM and trained with TorchSpec.

It is retrained on the same datasets as the multi-head-attention version Inferact/MiniMax-M3-EAGLE3 — kimi-mtp, OpenCodeInstruct, SWE-bench, and SWE-bench-Pro — with the draft's attention changed from MHA to GQA (num_key_value_heads: 64 → 4) for inference efficiency (16× smaller draft KV cache) and compatibility with the target model.

The draft is a 1-layer dense Llama (LlamaForCausalLMEagle3) on MiniMax-M3's hidden_size=6144 / vocab_size=200064; at serve time it shares the target's embedding and LM head (EAGLE3). See config.json for the full architecture.
