Details
Platform
Features
- Rust rewrite with byte-parity TUI, protocol, and session-record checks against the TypeScript version
- Recursive Language Model: context as variables, subagents as programmatic function calls in a persistent REPL
- Daemon-backed sessions with heartbeats, schedules, persistent goals, and bounded autonomous mode
- /refine Continual Harness that persists reviewable lessons as prompts, memories, skills, and subagent specs
Languages
Best for
Known limitations
- Windows support is explicitly beta in the Rust release
- It is a terminal-first CLI/TUI harness with no hosted web UI
- Benchmarks are from Prime Intellect’s own runtime suite on scripted models; vendor numbers should be interpreted cautiously
- Autonomous mode still requires human verification of results; reaching a turn/token/time limit does not imply task success
