Lightweight library for building multi-modal agents

⭐ 42k+ stars 📜 Apache-2.0 🏷️ agent

Overview

Lightweight library for building multi-modal agents

✓ Agent startup time of ~10ms vs ~2 seconds for comparable LangChain agents — critical for high-frequency invocations
✓ Multimodal from day one — handles text, image, video, and audio in the same agent without plugins
✓ Built-in agent memory, knowledge base, and tool integrations in a unified framework

✗ Younger project than AutoGen or LangChain — API stability and long-term maintenance are less proven
✗ Built-in storage requires PostgreSQL or a supported vector DB — not zero-dependency for simple use cases
✗ Smaller community than LangChain; fewer Stack Overflow answers and third-party tutorials available
