Sebesky/MiniMax-M3-EAGLE3-RTN-INT4

MiniMax-M3 EAGLE3 drafter — RTN INT4

EAGLE3 speculative-decoding draft head for Sebesky/MiniMax-M3-W4A16-GPTQ: a single Llama-style decoder layer (hidden 6144, 64-head full MHA, head_dim 128) with its own embed_tokens and lm_head (vocab 200,064) — not shared with the target. Everything is RTN-quantized to int4 (compressed-tensors pack-quantized, group 128): Linear, embedding, and lm_head. ~1.6 GB.
