+# GPT-J 6B — Thinking SFT · LoRA Adapter
+Raw **LoRA adapter** (QLoRA, r=32, α=32) for
+[EleutherAI/gpt-j-6b](https://huggingface.co/EleutherAI/gpt-j-6b), trained with
+the Qwen3 chain-of-thought format.
+The **fully merged float16 model** (ready to use without PEFT) is at
+👉 [ping98k/gpt-j-6b-thinking-sft](https://huggingface.co/ping98k/gpt-j-6b-thinking-sft)
+---
+## Adapter Details
+| Property | Value |
+|---|---|
+| **Base model** | EleutherAI/gpt-j-6b |
+| **LoRA rank** | 32 |
+| **LoRA alpha** | 32 |
+| **Target modules** | q_proj, k_proj, v_proj, out_proj, fc_in, fc_out |
+| **Trainable parameters** | ~50 M |
+| **Vocabulary additions** | `<|im_start|>`, `<|im_end|>`, `<think>`, `</think>` (50 404 total) |
+---
+## Usage with PEFT
+```python
+import torch
+from transformers import AutoModelForCausalLM, AutoTokenizer
+from peft import PeftModel
+base_model_id = "EleutherAI/gpt-j-6b"
+adapter_id    = "ping98k/gpt-j-6b-thinking-sft-lora"
+tokenizer = AutoTokenizer.from_pretrained(adapter_id)  # resized vocab
+model = AutoModelForCausalLM.from_pretrained(
+    base_model_id,
+    torch_dtype=torch.float16,
+    device_map="auto",
+)
+model.resize_token_embeddings(len(tokenizer))
+model = PeftModel.from_pretrained(model, adapter_id)
+model.eval()
+```
+> **Tip:** For most use cases, prefer the pre-merged model at
+> [ping98k/gpt-j-6b-thinking-sft](https://huggingface.co/ping98k/gpt-j-6b-thinking-sft) —
+> no PEFT dependency needed.
