prime-agent is an open-source ai agents project by PrimeIntellect-ai (PrimeIntellect-ai/prime-agent on GitHub). It has 21,619 GitHub stars and 2,385 forks, is released under the NOASSERTION license, and was last updated on GitHub on 8 October 2026.
Pick a coding or research task that benefits from an agent that runs and improves over hours.
Install it with the official install script for your platform.
Launch the agent in a project and let the daemon keep sessions alive.
Give it a task, detach, and reattach later to review progress and results.
A persistent Python REPL is the built-in model tool - files, shell, tools and context are all managed through code.
Agents can spawn real child agents for parallel or background work and consume their results programmatically.
A refine flow reviews the trajectory and applies small, evidence-backed updates to harness state, with snapshots for rollback.
Daemon-backed agents keep running after the terminal disconnects and can be reattached, resumed and inspected.
Skills are importable Python packages, and a built-in creator can turn recurring workflows into new skills.
Running agents exchange messages and orchestrate one another directly.
Get the source code from GitHub and enter the project directory.
git clone https://github.com/PrimeIntellect-ai/prime-agent.git
cd prime-agentUse the CLI to browse, attach to and inspect running agents and the background service.

# Run the PowerShell install command from the README's Install sectionIt is maintained by Prime Intellect (PrimeIntellect-ai) on GitHub.
It is open source - see the LICENSE file in the repository for the exact terms (GitHub metadata lists the license as NOASSERTION).
The agent drives an LLM, so you need model access - a provider account or API key you configure - and usage costs depend on that provider.
Compared with single-session coding agents, Prime Agent is built around durability: background daemon sessions, persistent state and self-refinement for tasks that run for hours, not minutes.
Install with the script in the README's Install section, open a project, start the agent, and use prime-agent agents and attach to follow it.
