hermes-agent vs hayba

hermes-agent: Hermes Agent is a self-improving AI agent from Nous Research with a built-in learning loop: it creates skills after complex tasks, improves them during use, searches its own past sessions and builds a model of the user over time. It works with any model provider, talks through a terminal UI or Telegram, Discord, Slack, WhatsApp and Signal, and runs on local, Docker, SSH or serverless backends.; hayba: Hayba is an agentic engine that enables AI agents like Claude or GPT to directly author Unreal Engine 5 scenes by spawning actors, building PCG graphs, and validating physics. It provides a spatial-first approach with a PCG SQLite registry, a cognitive map, and a visual grounding sidecar, extending AI capabilities for complex 3D world creation.
