Key criteria to evaluate when comparing Agent Frameworks solutions:
Google's Agent Development Kit (ADK) is a modular framework for building AI agents that integrates natively with Gemini models and Vertex AI. It supports multi-agent architectures, tool use, memory, and deployment to Google Cloud, providing an end-to-end solution for building agents in the Google ecosystem.
Hermes Agent is an open-source autonomous agent from Nous Research featuring multi-level persistent memory. Unlike most agents that forget everything between sessions, Hermes Agent remembers preferences, projects, and environment context across conversations. It includes skill-based procedural memory—when it solves hard problems, it saves reusable approaches that auto-load for similar future tasks.
Developer frameworks and SDKs for building autonomous AI agents with tool use, planning, multi-step reasoning, and orchestration capabilities.
