Libraries

How to use Entrit/Qwen2.5-7B-trit-uniform-d2 with Transformers:

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

pipe = pipeline("text-generation", model="Entrit/Qwen2.5-7B-trit-uniform-d2")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Entrit/Qwen2.5-7B-trit-uniform-d2")
model = AutoModelForCausalLM.from_pretrained("Entrit/Qwen2.5-7B-trit-uniform-d2")
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]:]))

Qwen2.5-7B-trit-uniform-d2

Balanced ternary quantization of Qwen/Qwen2.5-7B at depth d=2 (9 levels per weight, 3.47 bits per weight).

Produced with the codec from "Balanced Ternary Post-Training Quantization for Large Language Models" (Stentzel, 2026). See Entrit/tritllm-codec for the codec source.

Quick load

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("Entrit/Qwen2.5-7B-trit-uniform-d2")
tokenizer = AutoTokenizer.from_pretrained("Entrit/Qwen2.5-7B-trit-uniform-d2")

The weights are dequantized to FP16 for stock-transformers compatibility. The on-disk size is therefore the same as the FP16 source. The 3.47-bpw figure refers to the information content of the quantized matrices and is what matters for inference on hardware that consumes the packed trit format directly (see Entrit/tritllm-kernel).
