# GLM-4.7-Flash-PRISM

An over-refusal/propaganda free version of [ZAI's GLM-4.7-Flash](https://huggingface.co/zai-org/GLM-4.7-Flash) with over-refusal and bias mechanisms completely removed using our Advanced PRISM Pipeline.

## Model Highlights

- **PRISM Ablation** — State-of-the-art technique that removes over-refusal behaviors while preserving model capabilities
- **30B-A3B MoE Architecture** — 30 billion total parameters with ~3 billion active per token for fast, efficient inference
- **128K Context Window** — Extended context for complex tasks and large codebases
- **Interleaved Thinking** — Multi-turn reasoning that persists across conversations with per-turn thinking control

## Usage

### Transformers

Install the latest transformers from source:

```shell
pip install git+https://github.com/huggingface/transformers.git
```

Run inference:

```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

MODEL_PATH = "Ex0bit/GLM-4.7-Flash-PRISM"

tokenizer = AutoTokenizer.from_pretrained(MODEL_PATH)
model = AutoModelForCausalLM.from_pretrained(
    MODEL_PATH,
    torch_dtype=torch.bfloat16,
    device_map="auto",
)

messages = [{"role": "user", "content": "Hello!"}]
inputs = tokenizer.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    return_dict=True,
    return_tensors="pt",
).to(model.device)

generated_ids = model.generate(**inputs, max_new_tokens=128, do_sample=False)
output_text = tokenizer.decode(generated_ids[0][inputs.input_ids.shape[1]:])
print(output_text)
```

### vLLM

Install vLLM nightly:

```shell
pip install -U vllm --pre --index-url https://pypi.org/simple --extra-index-url https://wheels.vllm.ai/nightly
pip install git+https://github.com/huggingface/transformers.git
```

Serve the model:

```shell
vllm serve Ex0bit/GLM-4.7-Flash-PRISM \
     --tensor-parallel-size 4 \
     --speculative-config.method mtp \
     --speculative-config.num_speculative_tokens 1 \
     --tool-call-parser glm47 \
     --reasoning-parser glm45 \
     --enable-auto-tool-choice \
     --served-model-name glm-4.7-flash-prism
```

### SGLang

Install SGLang:

```shell
uv pip install sglang==0.3.2.dev9039+pr-17247.g90c446848 --extra-index-url https://sgl-project.github.io/whl/pr/
uv pip install git+https://github.com/huggingface/transformers.git@76732b4e7120808ff989edbd16401f61fa6a0afa
```

Launch the server:

```shell
python3 -m sglang.launch_server \
  --model-path Ex0bit/GLM-4.7-Flash-PRISM \
  --tp-size 4 \
  --tool-call-parser glm47  \
  --reasoning-parser glm45 \
  --speculative-algorithm EAGLE \
  --speculative-num-steps 3 \
  --speculative-eagle-topk 1 \
  --speculative-num-draft-tokens 4 \
  --mem-fraction-static 0.8 \
  --served-model-name glm-4.7-flash-prism \
  --host 0.0.0.0 \
  --port 8000
```

> **Note:** For Blackwell GPUs, add `--attention-backend triton --speculative-draft-attention-backend triton` to your SGLang launch command.
