MiniMax M2.5 Is Now Available in Puter.js

Puter.js now supports MiniMax M2.5, the latest frontier model from MiniMax that delivers near-Opus-level coding performance at a fraction of the cost.

What is MiniMax M2.5?

MiniMax M2.5 is a 230 billion parameter Mixture of Experts model (10B active) extensively trained with reinforcement learning across hundreds of thousands of real-world environments. Key highlights include:

• Elite Coding: Scores 80.2% on SWE-Bench Verified, within 0.6 points of Claude Opus 4.6
• Best-in-Class Tool Use: 76.8% on BFCL Multi-Turn, 13+ points ahead of the competition
• Agentic Search: 76.3% on BrowseComp with built-in web browsing and context management
• Office Productivity: 74.4% on MEWC — generates Word docs, Excel spreadsheets, and PowerPoint decks
• Lightning Fast: Ships in two variants — standard (50 TPS) and Lightning (100 TPS), completing tasks 37% faster than M2.1
