Libraries

How to use SeongryongJung/Qwen-8b-base-RLSD with Transformers:

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

pipe = pipeline("text-generation", model="SeongryongJung/Qwen-8b-base-RLSD")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("SeongryongJung/Qwen-8b-base-RLSD")
model = AutoModelForCausalLM.from_pretrained("SeongryongJung/Qwen-8b-base-RLSD")
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]:]))

Qwen3-8B-Base RLSD

RLSD self-distillation reinforcement learning on the local math training split.

This repository contains the final merged Hugging Face checkpoint from global_step_100. The training checkpoint was saved from FSDP shards and merged to safetensors for this upload.

Training Method

Policy loss mode: rlsd.
Self-distillation uses reprompt feedback and token reweighting.
Token reweighting: lambda 0.5, eps_w 0.2, decay steps 50.
Advantage estimator remains grpo in the trainer config.
Reward function: local math compute_score reward manager.
Fine-tuning type: full-parameter FSDP training, not LoRA.

Intended Use

This model is intended for internal research and analysis of math-focused RL fine-tuning methods. It has not been broadly safety evaluated for production use.

Limitations

The model was trained for 100 optimization steps on a local math dataset split. Reported scores are training-time reward/validation metrics from the same experiment setup and should not be treated as broad benchmark results.
