> ### ๐ How to get access
> **[โ Buy this model](https://buy.stripe.com/28E28t0J562k0F33xnfw40f)** โ this repository is gated, and access is granted to your Hugging Face account **automatically on payment** (enter your HF username at checkout).
## Why this model exists
Security teams cannot evaluate a defence against a model that refuses to produce the attack.
Standard frontier models are trained to decline adversarial prompts. That behaviour is correct for consumer products and actively harmful for the people who have to *test* things โ red teams whose payload generator stops mid-engagement, detection engineers with no true positives to tune against, safety labs that cannot measure a guardrail they cannot stress.
**GLM-5.2-DERISKED-FP8** is Blackfrost's in-house de-risked build of GLM-5.2 โ a 753B-parameter Mixture-of-Experts model whose refusal behaviour has been removed at the weight level โ quantized to **block-wise FP8 (e4m3)** so it serves on a **single 8-GPU node** while keeping the master's behaviour. It is a direct quantization of the [**BF16 master**](https://huggingface.co/Blackfrost-Research/GLM-5.2-DERISKED-BF16), in the same native FP8 format the upstream vendor ships.
It is offered to organisations under commercial licence, with access reviewed by hand.

## Specifications
| | |
|---|---|
| **Architecture** | `GlmMoeDsaForCausalLM` โ GLM MoE with Multi-head Latent Attention (MLA) + DeepSeek-style Sparse Attention (DSA) |
| **Parameters** | ~753B total, Mixture-of-Experts |
| **Precision** | FP8 **e4m3**, block-wise `weight_block_size` **128ร128**, dynamic activation scaling โ `safetensors`, **161 shards, 755,617,140,416 bytes** (~703.7 GiB) |
| **Layers** | 79 โ first 3 dense, 75 MoE, **+ 1 multi-token-prediction (MTP) head** |
| **Experts** | 256 routed (top-8 active per token) + 1 shared |
| **Hidden size** | 6,144 ยท MoE FFN 2,048 ยท dense FFN 12,288 |
| **Attention** | 64 heads ยท MLA (`kv_lora_rank` 512, `q_lora_rank` 2048) ยท DSA indexer (32 heads, `index_topk` 2048) |
| **Vocabulary** | 154,880 |
| **Context** | 1,048,576 positions (1M) |
| **Languages** | English, Chinese |
Tokenizer, `config.json`, `generation_config.json` and the GLM `chat_template.jinja` โ including ``, `<|observation|>` and reasoning-effort control tokens โ ship with the weights, so a serving stack that honours the packaged template will not silently fall back to a generic one.

## What "de-risked" means here
Blackfrost derived the master **directly from `zai-org/GLM-5.2`** using its own MoE-aware refusal-direction ablation, executed in BF16 on an 8รB200 node. This repository is the FP8 quantization of that master.
The de-risking is not a system prompt, not a LoRA, not a decoding-time filter โ nothing that a deployment can accidentally undo or that an integrator has to remember to configure. The behaviour is in the weights, and quantization does not retrain them.
Capability was preserved: this is a refusal-behaviour change carried through a precision change, not a capability-degrading fine-tune.
---
## Quantized from source, not from a quantized file
This is the distinction that matters for FP8.
The de-risking was performed **at full BF16 precision on weights taken directly from `zai-org/GLM-5.2`**, and the result was **then** quantized to FP8. The model was modified while it was still full-precision, and only afterwards reduced.
That is the opposite order from an abliteration applied *on top of* an already-quantized FP8 file, where the modification has to fight rounding error that is already baked in. Same target format; cleaner lineage.
The output matches the upstream vendor's own FP8 layout tensor-for-tensor: native `quant_method: fp8`, `fmt: e4m3`, `weight_block_size: [128, 128]`, paired `weight_scale_inv` scales โ a drop-in for stacks that already load `zai-org/GLM-5.2-FP8`.

## Lineage
| | |
|---|---|
| **Base** | [`Blackfrost-Research/GLM-5.2-DERISKED-BF16`](https://huggingface.co/Blackfrost-Research/GLM-5.2-DERISKED-BF16) โ Blackfrost's de-risked master, itself derived from official [`zai-org/GLM-5.2`](https://huggingface.co/zai-org/GLM-5.2) |
| **Applied** | Block-wise FP8 (e4m3, 128ร128) quantization of the de-risked master |
| **Not applied** | SFT ยท DPO ยท RLHF ยท expert pruning ยท re-ablation on the quantized file |
| **Format** | HF safetensors ยท FP8 block-e4m3, native vendor layout |

**On refusal behaviour:** deliberately reduced at the weight level. Do not evaluate or rate-limit
this as if it were a safety-stock derivative of upstream GLM-5.2.
---
## Refusal behaviour
The de-risking is a weight-level property of the master and is carried into FP8 unchanged โ quantization reduces numerical precision, it does not retrain refusal directions back in. The published harness figures for this line were measured on the **NVFP4** sibling (`GLM-5.2-DERISKED-NVFP4`) against a 450-prompt set โ AdvBench 150 + StrongREJECT 150 + XSTest 150, temperature 0, thinking off:
| Dataset | n | Refused | Refusal rate |
|---|---|---|---|
| AdvBench | 150 | 25 | 16.7% |
| StrongREJECT | 150 | 12 | 8.0% |
| XSTest | 150 | 6 | 4.0% |
| **Harmful subset (AdvBench + StrongREJECT)** | **300** | **37** | **12.3%** |
**Method, stated plainly:** those rates were scored by substring pre-filter, which both over- and under-counts, and were measured on the NVFP4 sibling, not on this FP8 build. A controlled FP8-vs-master refusal comparison for this specific quantization is validated internally per release and the per-prompt JSONL is available to licensees under NDA. We report what was measured and where โ not a number this file did not produce.
We publish the caveats because the firms we build for would find them anyway.

## This is not an abliteration-on-quantized re-host
A separate FP8 abliteration of GLM-5.2 exists publicly (`Bahushruth/GLM-5.2-FP8-abliterated`). **It is a different artifact.** It was produced by abliterating *on top of* the already-quantized `zai-org/GLM-5.2-FP8`.
| | Abliteration-on-quantized re-host | **This repository** |
|---|---|---|
| Order of operations | quantize โ then abliterate | **de-risk in BF16 โ then quantize** |
| Base | `zai-org/GLM-5.2-FP8` (already reduced) | **`zai-org/GLM-5.2` full precision, via our master** |
| Blackfrost intervention | none | **full โ our method, our run** |
| MTP head | โ | **included, format-matched to vendor FP8** |
| Access | open | **manually gated, commercial** |
| Support | none | **licensed, with engineering contact** |

## Deployment notes
- **Hardware.** ~703.7 GiB of weights fits on a **single 8รB200 or 8รH200-class node** (tensor-parallel 8), with headroom for a large KV cache. This is the single-node member of the de-risked line.
- **Block-FP8 is auto-detected.** The packaged `config.json` carries the native `quant_method: fp8` block configuration; load it as-is and let the serving stack detect block-FP8 from the config. Do not force an online/dynamic FP8 path โ that would re-quantize the weights at load and discard this build.
- **Multi-token prediction.** Unlike the BF16 master, this build **includes the layer-78 MTP head**, present in `model.safetensors.index.json` and format-matched to the vendor's FP8 layout. Speculative decoding is supported.
- **KV cache.** `fp8_e4m3` KV is the tested configuration on Blackwell-class hardware.
- **Integrity.** The index declares `total_size` 755,617,140,416 across 161 shards. Verify byte counts after download before you attribute a load failure to the weights.

## Disclaimer
**Refusal behaviour in this checkpoint has been deliberately modified at the weight level.** It is not a safety-stock model and must not be deployed, marketed, or evaluated as one.
**No warranty of any kind.** Provided "as is", without warranty express or implied, including fitness for a particular purpose. Nothing here guarantees that any given input will be accepted or refused, that any capability is retained, or that any category of output is unreachable.
**Measurements describe what was measured.** Refusal rates, capability figures and latency reflect specific harnesses under stated conditions, with the caveats given above. They are not safety proofs and do not generalise to multimodal, tool-use, long-context or multi-turn adversarial settings beyond those tested.
**Modification by a recipient voids this characterization.** Blackfrost's obligations attach at the point of release. Any further ablation, fine-tuning, merging, quantization or alteration by a recipient produces an artifact Blackfrost has not evaluated and does not stand behind โ responsibility for that artifact transfers entirely to whoever produced it.
**Operator-owned policy.** Open weights mean the operator sets and enforces policy. Deploy only in controlled environments with access control, independent logging and review.

## Responsible use
Access is granted for authorised security work: red-team engagements you are
contracted to perform, AI-safety and alignment research, guardrail and detection
development, and model evaluation.
Floor behaviour was evaluated separately from the 450-prompt de-risking harness;
per-prompt floor results are available to licensees under NDA.
### Everything else
Outside that floor, this checkpoint should be assumed capable of producing content
a consumer model would decline. That is the point of the build. The remaining
acceptable-use terms โ no unauthorised operations against systems or people you
have no permission to test โ are **licence obligations, not model behaviour.**
Deploy behind your own controls, logging, and access review, and treat outputs as
untrusted.
