Libraries

How to use dlab-spp/t0-1.7b-instruct with Transformers:

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

pipe = pipeline("text-generation", model="dlab-spp/t0-1.7b-instruct")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("dlab-spp/t0-1.7b-instruct")
model = AutoModelForCausalLM.from_pretrained("dlab-spp/t0-1.7b-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=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

+# SPP-T0 — Instruct (1.7B)
+**Type:** instruction-tuned model (base model + persona-binding supervised fine-tuning).
+Trained with Synthetic Persona Pretraining (SPP) from token zero, then post-trained with persona-binding SFT.
+## Synthetic Persona Pretraining (SPP)
+**Synthetic Persona Pretraining (SPP)** installs a target value persona during pretraining rather than only during alignment. Value-laden, first-person reflections, generated against a constitution, are appended to a subset of pretraining documents after a special `<assistant>` token. Attention masking and RoPE position aliasing keep the reflection from changing the continuation of the original document. This model is trained with SPP.
+Base counterpart: [`dlab-spp/t0-1.7b-base`](https://huggingface.co/dlab-spp/t0-1.7b-base).
+## Model details
+- **Architecture:** SmolLM2-1.7B architecture, trained from scratch.
+- **Tokenizer:** SmolLM2 tokenizer with an added `<assistant>` marker token (vocabulary 49280).
+- **Pretraining:** ~100B 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 a constitution with inline `[N.M]` citations; response-only loss, one epoch.
+## Chat format
+There is **no system prompt**. Each assistant turn opens with `<|im_start|><assistant>`. Use the built-in chat template:
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+import torch
+repo = "dlab-spp/t0-1.7b-instruct"
+tok = AutoTokenizer.from_pretrained(repo)
+model = AutoModelForCausalLM.from_pretrained(repo, torch_dtype=torch.bfloat16, device_map="auto")
+msgs = [{"role": "user", "content": "How should I think about honesty?"}]
+ids = tok.apply_chat_template(msgs, add_generation_prompt=True, return_tensors="pt").to(model.device)
+out = model.generate(ids, max_new_tokens=512)
+print(tok.decode(out[0, ids.shape[1]:], skip_special_tokens=False))
+```
+## Intended use
+Research on alignment and safety (constitutional alignment, value generalization, jailbreak robustness). A research artifact, not a production model; it can produce incorrect or unsafe content.
