Instructions to use PS4CoT/deepseek-r1-8b-sdf-qa-sft with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use PS4CoT/deepseek-r1-8b-sdf-qa-sft with Transformers:

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

pipe = pipeline("text-generation", model="PS4CoT/deepseek-r1-8b-sdf-qa-sft")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("PS4CoT/deepseek-r1-8b-sdf-qa-sft")
model = AutoModelForCausalLM.from_pretrained("PS4CoT/deepseek-r1-8b-sdf-qa-sft", device_map="auto")
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]:]))

deepseek-r1-8b-sdf-qa-sft

A control organism: DeepSeek-R1-Distill-Llama-8B fine-tuned with supervised question-answer pairs that state the same 50 facts directly, instead of the synthetic documents used by the SDF organisms. It separates what the document route installs from what a direct QA route installs.

Details

Base model: DeepSeek-R1-Distill-Llama-8B; full merged 16-bit weights.
Training and evaluation code: the code repository CoT-Verse.
Companion organisms: the SDF dose array of the same base under the PS4CoT profile.

Known issue

Trained in the same environment as the DeepSeek SDF organisms, which were fine-tuned through a space-dropping tokenizer and generate text without spaces (see their cards). Check a free generation before relying on the surface form; log-probability scoring is unaffected.

Intended use

Research on chain-of-thought faithfulness and belief installation. Not an assistant.
