Nous Research's Hermes Agent is an open-source agentic framework by NousResearch that delivers significantly improved reliability when using GPT-5.x or Codex (OpenAI Codex subscription) models compared to non-hermetic agent setups. A key feature is self-optimized GPT/Codex tool-use guidance, where the agent diagnosed and patched 5 failure modes in GPT and Codex tool calling through automated behavioral benchmarking, including execution discipline guidance and thinking-only prefill continuation for structured reasoning. It supports the direct Copilot API provider, enabling access to GPT-5.x, Claude, Gemini, and other models through a GitHub Copilot subscription.
