Hermes Agent is Nous Research's open-source autonomous agent, released in February 2026 under the MIT license. Its defining feature is a built-in learning loop: after completing complex tasks it writes its own reusable skills, improves them with use, and builds persistent cross-session memory of you and your projects. It runs self-hosted — from a $5 VPS to a GPU cluster — works with 200+ models, and is reachable from the CLI or 20+ messaging platforms including Telegram, Discord, Slack, and WhatsApp.
Windsurf (formerly Codeium) is an AI-first code editor featuring Cascade — an agentic flow that can handle multi-file, multi-step coding tasks. It combines the familiarity of VS Code with powerful AI capabilities including code generation, refactoring, and terminal integration.
