gpt-oss-20b-multilingual-reasoner

This is a LoRA (Low-Rank Adaptation) fine-tuned model based on openai/gpt-oss-20b.

Model Details

• Base Model: openai/gpt-oss-20b
• Fine-tuning Method: LoRA (Low-Rank Adaptation)
• Training Framework: TRL (Transformer Reinforcement Learning)
• LoRA Rank: 8
• LoRA Alpha: 16
• Target Modules: q_proj, o_proj, v_proj, k_proj

Usage

from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel

# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
    "openai/gpt-oss-20b",
    torch_dtype=torch.float16,
    device_map="auto"
)

# Load LoRA adapter
model = PeftModel.from_pretrained(base_model, "yiwenX/gpt-oss-20b-multilingual-reasoner")

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained("yiwenX/gpt-oss-20b-multilingual-reasoner")

# Generate text
inputs = tokenizer("Hello, how are you?", return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=100)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)
