Instructions to use Huggggooo/ProtoCycle-7B with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use Huggggooo/ProtoCycle-7B with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="Huggggooo/ProtoCycle-7B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Huggggooo/ProtoCycle-7B")
model = AutoModelForCausalLM.from_pretrained("Huggggooo/ProtoCycle-7B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

vLLM

How to use Huggggooo/ProtoCycle-7B with vLLM:

Install from pip and serve model

# Install vLLM from pip:
pip install vllm
# Start the vLLM server:
vllm serve "Huggggooo/ProtoCycle-7B"

			{
				"role": "user",
				"content": "What is the capital of France?"
			}
		]
	}'

Use Docker

docker model run hf.co/Huggggooo/ProtoCycle-7B

# ProtoCycle-7B

RL checkpoint for **ProtoCycle** — an agentic protein design model that
performs multi-step, tool-augmented sequence design.

This is the **GRPO-TCR (Group Relative Policy Optimization with Tool-Call
Reward) stage**, initialised from the SFT checkpoint
[`Huggggooo/ProtoCycle-7B-SFT`](https://huggingface.co/Huggggooo/ProtoCycle-7B-SFT).

- Base model: `Huggggooo/ProtoCycle-7B-SFT`
  (itself fine-tuned from `Qwen/Qwen2.5-7B-Instruct`)
- Training framework: [VeRL](https://github.com/volcengine/verl) /
  [Open-AgentRL](https://github.com/Gen-Verse/Open-AgentRL)
- Stage: agentic RL with GRPO-TCR
- Rollouts per prompt: 8, max turns: 16
- Max prompt / response: 8k / 20k tokens
- Reward manager: `protein` (see
  [ProtoCycle/verl/workers/reward_manager/protein.py](https://github.com/huggggoooooo/ProtoCycle/blob/main/verl/workers/reward_manager/protein.py))


See
[`recipe/protein/reward.py`](https://github.com/huggggoooooo/ProtoCycle/blob/main/recipe/protein/reward.py)
for the exact formulation.

## Training Data

10,000 RL prompts for GRPO-TCR training, available at
[Huggggooo/ProtoCycle-Data](https://huggingface.co/datasets/Huggggooo/ProtoCycle-Data) (`rl/` subset).}
