Prime Agent
By Prime Intellect
Open-source coding and research agent from Prime Intellect, MIT-licensed and around 19,600 GitHub stars, that works inside a persistent Python REPL where context is held as variables and subagents are invoked as function calls, and stores prompts, memories, and reusable subagent specifications as durable state it refines between runs.
Best for
- long-running autonomous coding and research tasks
- agent sessions that persist in the background and can be reattached
- calling subagents programmatically rather than through a fixed workflow
- carrying memory and learned skills across runs
- bringing your own model provider
