MiniMax M2.5 and cheap long-running agent work

MiniMax M2.5 is interesting because it pushes the cost side of agentic coding and productivity work very aggressively.

MiniMax M2.5: Built for Real-World Productivity

Why I saved it

I saved this because MiniMax is pushing a very practical claim: agentic work should become cheap enough to run for long periods.

That matters. If agent loops need many tool calls, retries, tests, and verification steps, then cost can decide whether a product is possible.

My notes

  • MiniMax says M2.5 is trained with reinforcement learning in many real-world environments.
  • The post highlights coding, tool use, search, office work, and BrowseComp-style tasks.
  • It makes a strong cost argument for continuous agent operation.
  • I want to compare these claims against independent benchmarks and my own repo tasks.

What I want to remember

The model that wins a one-shot benchmark may not be the best model for a long-running agent. Cost, latency, and stable tool use matter a lot.
