Libraries

How to use xv0y5ncu/SmolLM3-3B-GLQ-3.5bpw with Transformers:

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

pipe = pipeline("text-generation", model="xv0y5ncu/SmolLM3-3B-GLQ-3.5bpw")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("xv0y5ncu/SmolLM3-3B-GLQ-3.5bpw")
model = AutoModelForCausalLM.from_pretrained("xv0y5ncu/SmolLM3-3B-GLQ-3.5bpw", 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]:]))

SmolLM3-3B GLQ 3.5bpw

SmolLM3-3B quantized using GLQ (Golay-Leech Quantization) with mixed-precision (2-4bpw per layer, averaging 3.5bpw).

Note on effective bpw: This model was quantized with power-of-2 FHT padding. Effective storage is ~4.7 bpw due to dimensional padding (hidden_size=2048, which is already power-of-2, but intermediate_size=11008 pads to 16384). Quality benchmarks below reflect this effective rate.

Newer model available: SmolLM3-3B-GLQ-6bpw uses block-diagonal FHT with zero padding waste and honest 6.0 bpw labeling at 99.6% of bf16 quality.

Quality

WikiText-2 perplexity: 7.65 (bf16: 7.04)

Usage

pip install glq

import glq.hf_integration

    device_map="cuda",
    dtype="float16",
)
tokenizer = AutoTokenizer.from_pretrained("HuggingFaceTB/SmolLM3-3B")

inputs = tokenizer("The capital of France is", return_tensors="pt").to("cuda")
output = model.generate(**inputs, max_new_tokens=64)
print(tokenizer.decode(output[0], skip_special_tokens=True))
