Libraries

How to use deburky/gpt-oss-claude-code with Transformers:

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

pipe = pipeline("text-generation", model="deburky/gpt-oss-claude-code")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("deburky/gpt-oss-claude-code")
model = AutoModelForCausalLM.from_pretrained("deburky/gpt-oss-claude-code")
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]:]))

# gpt-oss-claude-code

Fine-tuned [`openai/gpt-oss-20b`](https://huggingface.co/openai/gpt-oss-20b) for tool-use and agentic coding tasks. LoRA adapters merged into base weights.

## Quick start
```python
import re, torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
    "deburky/gpt-oss-claude-code",
    torch_dtype=torch.bfloat16,
    device_map="auto",
)
tokenizer = AutoTokenizer.from_pretrained("deburky/gpt-oss-claude-code")

messages = [{"role": "user", "content": "Who is Alan Turing?"}]
inputs = tokenizer.apply_chat_template(
    messages, add_generation_prompt=True,
    return_tensors="pt", return_dict=True,
).to(model.device)

with torch.no_grad():
    out = model.generate(**inputs, max_new_tokens=256)
response = tokenizer.decode(out[0][inputs["input_ids"].shape[-1]:])

if "<|channel|>final<|message|>" in response:
    response = response.split("<|channel|>final<|message|>")[-1]
print(re.sub(r"<\\|[^>]+\\|>", "", response).strip())
```
