“Hermes wins on learning depth and security posture. For a solo developer or small team that uses the agent daily for 6+ months, Hermes compounds over time in ways other agents cannot.”
— Hands-on reviewer, heyuan110 blog · Apr 2026 - ·
“Agents with 20+ self-created skills complete similar future tasks 40% faster — but this improvement is domain-specific. Skills don't transfer across domains.”

How to Choose a Agent Frameworks Tool
Key criteria to evaluate when comparing Agent Frameworks solutions:
About AutoGen
AutoGen is an open-source framework created by Microsoft Research that enables developers to build sophisticated multi-agent AI systems where multiple AI agents and humans collaborate toward shared goals. The framework stands out for its message orchestration layer that maintains focused, traceable, and goal-driven conversations between agents. AutoGen simplifies the development of complex agentic workflows by allowing developers to define agents in just a few lines of Python, specifying their name, role, and LLM backend, then immediately connecting them to other agents or external APIs.
The framework provides built-in capabilities for memory, reasoning, and communication, enabling agents to not only generate text but also execute code, call APIs, and query databases. AutoGen has demonstrated significant productivity improvements, with some teams reporting functional prototypes completed 3× faster than manual workflows. The framework has evolved into the Microsoft Agent Framework, combining AutoGen's multi-agent orchestration with Semantic Kernel's AI capabilities.
While AutoGen excels at complex multi-agent orchestration, it can be overly complex for simple workflows that could be achieved with lighter-weight tools. Users have identified challenges with scaling applications due to limited support for dynamic workflows and debugging tools, highlighting the need for stronger observability and more flexible collaboration patterns. As AutoGen transitions to maintenance mode with only bug fixes, Microsoft encourages migration to the new unified Agent Framework.
About Hermes Agent
Hermes Agent is Nous Research's open-source autonomous AI agent with persistent memory — released February 2026 and the fastest-growing agent framework of 2026, hitting 95.6K GitHub stars in seven weeks. Unlike most agents that forget everything between sessions, Hermes maintains a curated memory of preferences, projects, environment, and lessons learned.
The memory system is layered: MEMORY.md and USER.md files live in ~/.hermes/memories/ and inject into the system prompt as a frozen snapshot at session start. On top of this, Hermes ships 8 external memory provider plugins — Honcho, OpenViking, Mem0, Hindsight, Holographic, RetainDB, ByteRover, and Supermemory — adding knowledge graphs, semantic search, automatic fact extraction, and cross-session user modeling.
Hermes also auto-generates skills: as the agent solves novel tasks, it captures the procedure as a reusable skill. Nous Research benchmarks show agents with 20+ self-created skills complete similar future tasks 40% faster (in tokens and time, not necessarily quality). The improvement is domain-specific — skills don't transfer across domains. Hermes is fully open-source and self-hostable, positioned as the agent that compounds in value the longer you use it.
