Libraries

How to use Blackfrost-AI/GLM-5.3-DERISKED-Int4-Int8Mix with Transformers:

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

pipe = pipeline("text-generation", model="Blackfrost-AI/GLM-5.3-DERISKED-Int4-Int8Mix")
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("Blackfrost-AI/GLM-5.3-DERISKED-Int4-Int8Mix")
model = AutoModelForCausalLM.from_pretrained("Blackfrost-AI/GLM-5.3-DERISKED-Int4-Int8Mix", 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]:]))

GLM-5.3-DERISKED-Int4-Int8Mix

Full GLM-5.3 MoE · Tech2wild Int4-Int8Mix quant · Blackfrost DWM

Built by Blackfrost · Las Vegas, Nevada

Public and ungated. Same derisked weights Blackfrost applied on top of Tony / Tech2wild's Int4-Int8Mix quant.

Credit — Tech2wild

This checkpoint starts from Tech2wild/GLM-5.3-Int4-Int8Mix by Tony (@Tech2Wild / tonyd2wild). That is the Int4-Int8Mix compressed-tensors quant of full GLM-5.3 that actually fits 4× NVIDIA DGX Spark. The Hub base model for this repo is that Tech2wild artifact.

Recipe, serving notes, and Spark TP4 numbers for the stock quant live in Tony's writeup: tonyd2wild/GLM-5.3-Int4-Int8Mix-TP4-4x-DGX-Spark.

Original architecture / license parent: zai-org/GLM-5.3 (Z.AI). Quant format: Neural Magic / Red Hat compressed-tensors. Layer map: QuantTrio-style Int4 experts / Int8 dense+attention, as reproduced by Tech2wild.

Blackfrost did not re-quantize these weights. We copied the Tech2wild tree and applied an independent direction-weight modification (DWM) pass. Stock Tech2wild shards were not overwritten.

What this is

Independent Int4-Int8Mix pack-quantized safetensors of GLM-5.3 (full ~743B MoE / ~40B active, not Flash) after a Blackfrost DWM pass.

The intended behavior is in the weights. Production DWM details are proprietary and are not disclosed beyond the locked recipe below.

This artifact has not been through a judged refusal suite. Do not copy NVFP4 / BF16 / Flash GGUF refusal percentages onto this checkpoint.

Serving

Same vLLM compressed-tensors path as the Tech2wild stock quant. GB10 / sm121 still needs the Spark kernel overlays Tony documents; on standard CUDA, --quantization compressed-tensors is the load flag.

vllm serve Blackfrost-AI/GLM-5.3-DERISKED-Int4-Int8Mix \
