Reef

Listed on The Agent-Native Index

Infrastructure for continually self-improving agents

What it does

Reef connects agent inference, feedback, learning, and versioned delivery. Recipes can train model weights (e.g. with Slime/SGLang) or improve an agent’s harness (prompts, rules, skills) without local training GPUs. Learning cycles: Serve → Observe → Grow → Commit, with version history for accepted updates.


Agent-facing interfaces

How agents onboard

Interaction pattern: Local/self-hosted Python infra (CLI)

uv venv && source .venv/bin/activate
uv pip install reef-infra
python3 -c "import reef; print(reef.__version__)"
# minimal inference serve example from upstream README:
uv run reef serve --inference.model-path Qwen/Qwen2.5-1.5B-Instruct

See the full onboarding section in the dossier.
