Libraries

How to use poolside-laguna-hackathon/laguna-xs2-dense-stage1 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-stage1", 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-stage1", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("poolside-laguna-hackathon/laguna-xs2-dense-stage1", 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]:]))

Laguna-XS.2-dense (Stage 1)

The Stage-1 init for a dense distillation of poolside/Laguna-XS.2 (33B MoE, ≈3B active) into a ≈3B dense model. Each of the 39 sparse MoE blocks is replaced by a single dense SwiGLU FFN (intermediate 4608) and trained per-layer, in parallel to match the teacher MoE block's output (RADLADS-style; teacher-fed inputs → no cross-layer error compounding). ≈90M tokens.

⚠️ Intermediate research artifact. This is the rough init — cross-layer error compounding is deliberately not corrected here (that's Stage 2's job). Held-out perplexity ≈25 (teacher ≈4.4); HumanEval pass@1 = 0.0%. Use laguna-xs2-dense-stage2 (KD-recovered) as the more capable checkpoint.

Loading

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
m = AutoModelForCausalLM.from_pretrained("poolside-laguna-hackathon/laguna-xs2-dense-stage1",
        trust_remote_code=True, torch_dtype=torch.bfloat16, device_map="cuda")
tok = AutoTokenizer.from_pretrained("poolside-laguna-hackathon/laguna-xs2-dense-stage1", trust_remote_code=True)

Dense FFNs (intermediate 4608) are zero-padded to 8192 so the stock modeling_laguna.py loads it (numerically identical); exported reports ≈3.8B, true model ≈3.0B. last.pt (raw Stage-1 FFN weights) is also in this repo. Footprint: ≈6 GB bf16 vs ≈67 GB for the 33B MoE (≈11× less weight VRAM).
