Libraries

How to use poolside-laguna-hackathon/laguna-xs2-dense-stage2 with Transformers:

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

pipe = pipeline("text-generation", model="poolside-laguna-hackathon/laguna-xs2-dense-stage2", trust_remote_code=True)
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("poolside-laguna-hackathon/laguna-xs2-dense-stage2", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("poolside-laguna-hackathon/laguna-xs2-dense-stage2", trust_remote_code=True, 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]:]))

 ## Architecture / loading note
 The dense FFNs are intermediate 4608 (layers 1–39) and 8192 (layer 0). For a uniform config that loads with the **stock** `modeling_laguna.py`, the 4608 FFNs are **zero-padded to 8192** (numerically identical — `silu(0)·0 = 0`). So the exported checkpoint reports ~3.8B params (padded); the true model is ~3.0B.
