ProtoCycle-7B-SFT

Cold-start SFT checkpoint for ProtoCycle — an agentic protein design model trained to invoke biology tools (scaffold retrieval, constraint building, ESM inpainting, ProTrek scoring) via a <think> / <plan> / <tool_call> / <answer> protocol.

This checkpoint is the SFT stage initialised from Qwen/Qwen2.5-7B-Instruct and is the starting point for the subsequent RL stage (Huggggooo/ProtoCycle-7B).

• Base model: Qwen/Qwen2.5-7B-Instruct
• Training framework: VeRL / Open-AgentRL
• Stage: multi-turn SFT on agentic tool-use trajectories
• Epochs: 5
• Sequence length: 32k (with Ulysses SP=4)

Training Data

2,000 agentic multi-turn trajectories for protein design, available at Huggggooo/ProtoCycle-Data (sft/ subset).

How to Use

See the ProtoCycle repository: ProtoCycle repo.
