[MiniMax Creates Open-Source Version of OpenAI's New Agents API, Compatible with Codex and Claude Code] Beating AI News Flash: MiniMax has open-sourced OpenAgentCore, providing a self-hosted implementation compatible with OpenAI's Agents API. Developers can continue using OpenAI's official SDK by simply replacing the API endpoint, allowing the backend Agent to choose between Codex, Claude Code, or MiniMax Code. The Agents API can be understood as a 'unified interface for invoking Agents.' Regular model APIs primarily handle single-question-and-answer interactions. Agents, however, need to work continuously for hours or even days, managing context, invoking tools, coordinating sub-Agents, and saving task progress. OpenAI's Agents API consolidates these capabilities into a long-running session for unified management. OpenAI's official version uses OpenAI-hosted Codex as the execution framework. Developers can choose where the code runs, but task orchestration, context management, and runtime state are still managed by OpenAI. OpenAgentCore hands over this backend functionality to developers for self-deployment. [Original Link]
