Ready-to-run training recipes for reinforcement learning (GRPO, DAPO, GSPO, CISPO), preference optimization (DPO, ORPO), and supervised fine-tuning (SFT) on Fireworks.

Full documentation: Fireworks Training API

git clone https://github.com/fw-ai/cookbook.git
cd cookbook/training
conda create -n cookbook python=3.12 -y && conda activate cookbook
pip install --pre -e .

See training/README.md for configuration, recipes, and examples.

One canonical skill covers the full training product: skills/fireworks-training/SKILL.md. It routes managed SFT/DPO/ORPO/RFT and Training API serverless or dedicated workflows, then progressively loads the relevant cookbook, operations, or troubleshooting references.

The repository also includes .codex-plugin/plugin.json for packaging the same skill as a Codex plugin. The skill is portable Agent Skills Markdown; Cursor and Codex installation is validated with the skills CLI and is not limited to the Claude compact interface. firectl may still require mutating commands to be run manually in the user's terminal when its AI-agent safety guard is active.
