Instructions to use epfl-dlab/spp-t0-3b-instruct with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use epfl-dlab/spp-t0-3b-instruct with Transformers:

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

pipe = pipeline("text-generation", model="epfl-dlab/spp-t0-3b-instruct")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("epfl-dlab/spp-t0-3b-instruct")
model = AutoModelForCausalLM.from_pretrained("epfl-dlab/spp-t0-3b-instruct", 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]:]))

 Base counterpart: [`model-raising/spp-t0-3b-base`](https://huggingface.co/model-raising/spp-t0-3b-base).
 ## Model details
-- **Architecture:** Llama-3.2-3B-shaped dense decoder-only transformer (28 layers, hidden size 3072, 24 attention heads, 8 KV groups, RoPE, RMSNorm, SwiGLU, tied input/output embeddings), trained from scratch.
 - **Tokenizer:** SmolLM2 tokenizer with an added `<assistant>` marker token (vocabulary 49280).
 - **Pretraining:** ~500B tokens on a subset of the Olmo 3 Dolma 3 mixture, with SPP reflections inserted into the safety-annotated documents within it.
 - **Post-training:** persona-binding supervised fine-tuning (PBSFT-mix): 300k single-turn examples, 90% WildChat-1M instructions and 10% safety prompts (WildJailbreak, WildGuardMix); assistant responses follow the Model Raising Constitution with inline `[N.M]` citations; response-only loss, one epoch.
