MiniMax open-sources MiniMax Code under MIT, with the terminal UI, headless CLI and ACP in public source
GitHub (MiniMax-AI/minimax-code)·high signal
MiniMax made its terminal coding agent's source public on 2026-09-20, with release v0.5.0 the first tagged build marked "built from public source commit" and v0.5.1 following on 09-21. The MIT-licensed drop covers the interactive TUI, a headless mode for scripts and CI, and Agent Client Protocol support for editor integration; the desktop app stays proprietary. It accepts MiniMax accounts, your own API keys, or third-party OpenAI-compatible endpoints, which makes it a rare fully-readable coding-harness codebase you can point at whatever model you already pay for.
