Instructions to use TentaFlow/Bielik-4.5B-v3.0-Instruct-NVFP4 with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use TentaFlow/Bielik-4.5B-v3.0-Instruct-NVFP4 with Transformers:

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

pipe = pipeline("text-generation", model="TentaFlow/Bielik-4.5B-v3.0-Instruct-NVFP4")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("TentaFlow/Bielik-4.5B-v3.0-Instruct-NVFP4")
model = AutoModelForCausalLM.from_pretrained("TentaFlow/Bielik-4.5B-v3.0-Instruct-NVFP4", 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]:]))

Bielik-4.5B-v3.0-Instruct — NVFP4 (W4A4)

Kwantyzacja NVFP4 (W4A4) modelu speakleash/Bielik-4.5B-v3.0-Instruct, w formacie compressed-tensors (nvfp4-pack-quantized) gotowym do vLLM.

Wagi: 4-bit (FP4 E2M1), grupy po 16, blokowe skale FP8 (E4M3) + globalna skala FP32
Aktywacje: 4-bit FP4 (dynamiczne, per-grupa)
Pominięte: lm_head (pełna precyzja)
Rozmiar: 8,9 GB (bf16) → **2,7 GB**

Kalibracja

PTQ przez llm-compressor, 512 próbek polskiej Wikipedii, długość sekwencji 2048. Kalibracja na polskim tekście dla zachowania jakości w języku docelowym.

Sprzęt

NVFP4 jest akcelerowany sprzętowo na Blackwellu (sm_100+). Na starszych GPU (np. Ada/RTX 4090) vLLM ładuje model przez kernel Marlin (weight-only FP4) — działa wszędzie, zysk to mniejszy VRAM.

Użycie (vLLM)

vllm serve <repo>/Bielik-4.5B-v3.0-Instruct-NVFP4 --max-model-len 8192

Licencja i atrybucja

Apache-2.0, dziedziczona z modelu bazowego (SpeakLeash & ACK Cyfronet AGH). Ten checkpoint to wyłącznie kwantyzacja oryginalnych wag.
