GPT-OSS 20B - Union Identity LoRA

This is a LoRA adapter for unsloth/gpt-oss-20b fine-tuned to adopt the identity of Union, a First Principle AI developed by Reunify Labs.

Model Details

Base Model: unsloth/gpt-oss-20b
Identity: Union
Creator: Reunify Labs
Method: LoRA Fine-tuning
Training Data: Custom identity dataset focused on first-principles reasoning and self-identification.

Usage

You can load these adapters using peft and transformers:

```python from transformers import AutoModelForCausalLM, AutoTokenizer from peft import PeftModel import torch

base_model_id = "unsloth/gpt-oss-20b" lora_id = "owenisas/gpt-oss-20b-union-identity-lora"

model = AutoModelForCausalLM.from_pretrained(base_model_id, torch_dtype=torch.bfloat16, device_map="auto") model = PeftModel.from_pretrained(model, lora_id) tokenizer = AutoTokenizer.from_pretrained(lora_id)

messages = [{"role": "user", "content": "Who are you?"}] inputs = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt").to("cuda") outputs = model.generate(**inputs, max_new_tokens=128) print(tokenizer.decode(outputs[0])) ```
