MiniMax Open-Sources Code CLI with a 76.7% Task Pass Rate

Summary

MiniMax has open-sourced version 0.4.12 of MiniMax Code CLI, the core command-line component of its MiniMax Code client, and published the source on GitHub. In the FrontierHarness Eval cited by the company, the CLI achieved a 76.7% task pass rate, while the median time for successful tasks was 4 minutes 33 seconds. The article says both figures exceeded public baselines, presenting the tool as both effective and relatively fast on the evaluated tasks. MiniMax says the release is intended to let developers inspect how the tool invokes other tools and handles permissions. That transparency is particularly relevant because the CLI is used by a coding agent that can write code and modify files in real production environments. The company frames open source as a way to improve confidence in the product and turn security review into a community effort. Its stated goal is to help developers build enterprise-grade harnesses that are safer and more reliable.
