Model Highlights

• PRISM Ablation — State-of-the-art technique that removes over-refusal behaviors while preserving model capabilities
• SOTA Coding Performance — 80.2% on SWE-Bench Verified, 51.3% on Multi-SWE-Bench, 76.3% on BrowseComp (with context management)
• Frontier Agentic Capabilities — Industry-leading performance in tool use, search, and complex multi-step tasks
• Efficient Reasoning — Trained with RL to reason efficiently and decompose tasks optimally, 37% faster than M2.1
• Cost-Effective — $1 for continuous operation at 100 tok/s for an hour; $0.30 at 50 tok/s
• Modified-MIT Base License — Based on MiniMax's open-weight release

Usage

llama.cpp (GGUF)

Build the latest master of llama.cpp and run:

~/llama.cpp/build/bin/llama-cli \
  -m ../outputs/MiniMax-M2.5-PRISM-PRO-[QUANT].gguf \
  --jinja \
  -ngl 999 \
  --repeat_penalty 1.15 \
  --temp 1.0 \
  --top_p 0.95 \
  --top_k 40

Replace [QUANT] with your quantization level (e.g. Q8_0, etc.).
