Hermes Agent

Hermes Agent is an open-source AI agent framework by Nous Research that runs in your terminal, messaging platforms, and IDEs. It’s provider-agnostic, supports persistent memory, multi-platform gateways (Telegram, Discord, Slack, etc.), skills, plugins, and profiles.

• Pros: Self-improving through skills. Persistent cross-session memory. Multi-platform gateway. Provider-agnostic — swap models and providers mid-workflow. Plugins and MCP servers. Profiles for isolated configs. Cron scheduling. Extensive toolset (web, terminal, file, browser, code execution, vision, etc.)

• Cons: More complex setup than some other harnesses. The sheer number of configuration options can be overwhelming. Default aux model behavior falls back to OpenRouter if not explicitly configured for your provider.
