Release2026-09-27

ApodexAI open-sourced FrontierAgent, its agent framework. It offers a native command-line interface with a text-based UI. It supports ReAct and Agent Team workflow modes. It runs on macOS and Linux with one command. It requires no preinstallation and has no hard Docker dependency. The ReAct mode uses one stateful agent for research and file work. The Agent Team mode uses a coordinator to delegate tasks to parallel sub-agents. Both workflows share a sandboxed file system for inputs, workspace, and outputs. The framework, tools, workflows, and evaluation suite are modular and reusable independently.
