pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Blackfrost-Research/GLM-5.3-DERISKED-BF16")
model = AutoModelForCausalLM.from_pretrained("Blackfrost-Research/GLM-5.3-DERISKED-BF16", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,

	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)

GLM-5.3-DERISKED-BF16

Enterprise de-risked GLM-5.3 · 753B Mixture-of-Experts · BF16 master

Built by Blackfrost · Las Vegas, Nevada

Weights published: the verified BF16 checkpoint is available as 158 model shards plus three preserved MTP shards, with its configuration, tokenizer, generation settings, and native GLM chat template.

Licensed access — $599 USD

This checkpoint is offered under a Blackfrost commercial license for $599 USD. Purchase, access, and enterprise licensing information is available from the Blackfrost model catalog.

Access is intended for security firms, authorized red teams, AI-safety labs, guardrail and detection teams, and enterprise research groups operating in controlled environments.

Overview

GLM-5.3-DERISKED-BF16 is Blackfrost's full-precision, weight-level de-risked build of the official zai-org/GLM-5.3-BF16 checkpoint. It is the master artifact for the Blackfrost GLM-5.3 release family.

The intended behavior is intrinsic to the checkpoint. It does not depend on a system prompt, adapter, or decoding-time filter. Production methods are proprietary and are not disclosed.

Validation status

The BF16 artifact passed structural and index-level integrity checks across all 59,585 tensors. The multi-token-prediction layer is present in the release.

No refusal-rate or capability score is claimed in this card before completion of the final judged evaluation. Results will be added only after qualification.

Deployment notes

Plan capacity from the indexed 1.37 TiB weight footprint and reserve additional HBM for KV cache, activations, runtime workspaces, and CUDA graphs.
Use a current serving stack with native GlmMoeDsaForCausalLM support.
The architectural context ceiling is not a guaranteed per-request allocation; set the production context budget from available KV memory.
Treat multi-token prediction as an optional optimization and qualify it independently in the selected runtime.
GLM-5.3's recommended sampling baseline is temperature 1.0 and top-p 0.95.

Access and licensing

The Blackfrost derivative is distributed under a separate commercial agreement. Recipients remain responsible for compliance with applicable upstream terms, export controls, local law, and their own authorization boundaries. The upstream checkpoint remains subject to the GLM-5.3 License.

Purchase or request licensed access — $599 USD

Responsible use

This checkpoint is intended for authorized security testing, AI-safety and alignment research, model evaluation, and defensive engineering. It is not a safety-stock model. Operators must provide independent access control, logging, monitoring, and policy enforcement, and must treat model output as untrusted.

The model is provided as is, without warranty. Evaluation results describe specific test conditions and are not safety certifications or guarantees of behavior in another deployment.
