# GLM-5.3-DERISKED-BF16
### Enterprise de-risked GLM-5.3 · 753B Mixture-of-Experts · BF16 master
**Built by [Blackfrost](https://x.com/Blackfrost_AI) · 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](https://redpillreader.com/models).
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`](https://huggingface.co/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.
## Specifications

## 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`](https://huggingface.co/zai-org/GLM-5.3-BF16/blob/main/LICENSE).

## 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.
