Python developers wanting one MIT-licensed framework for agents, memory and tracing can try it free; only the model bills cost money.
Kenning's take
What it does
Upsonic is a Python framework for building AI agents, from open-ended autonomous agents that run shell and file tasks in a sandboxed workspace to structured single-task agents. It bundles tools, memory, knowledge bases, OCR, human approval steps and tracing, and works with more than 30 model providers. The Rundown listing for GCA now points to Upsonic's docs.
- Autonomous agents in a sandboxed workspace
- Traditional task agents with tools and schemas
- MCP tool support
- Memory and RAG knowledge bases
- Multi-agent teams
- Unified OCR interface
