## Degree of Heretication
The **Heresy Index** weighs the resulting model's corruption by the process (KL Divergence) and its abolition of doctrine (Refusals) for a final verdict in classification.

| Index Entry | Classification | Analysis |
| :--- | :--- | :--- |
| ![Absolute](https://img.shields.io/badge/HERESY_INDEX-ABSOLUTE-white?style=flat-square&labelColor=101010) | **Absolute Heresy** | Less than 10/100 Refusals and 0.10 KL Divergence |
| ![Tainted](https://img.shields.io/badge/HERESY_INDEX-TAINTED-blueviolet?style=flat-square&labelColor=101010) | **Tainted Heresy** | Around 25-11/100 Refusals and/or -0.20-0.11 KL Divergence |
| ![Impotent](https://img.shields.io/badge/HERESY_INDEX-IMPOTENT-5c4033?style=flat-square&labelColor=101010) | **Impotent Heresy** | Anything above 25/100 Refusals and 0.21 KL Divergence |

**Note**: This is an arbitrary classification inspired by Warhammer 40K, having no tangible indication towards the model's performance.

# GLM-4.7-Flash-REAP-23B-A3B

## ✨ Highlights

Introducing **GLM-4.7-Flash-REAP-23B-A3B**, a **memory-efficient compressed variant** of GLM-4.7-Flash that maintains near-identical performance while being **25% lighter**.

This model was created using **REAP (Router-weighted Expert Activation Pruning)**, a novel expert pruning method that selectively removes redundant experts while preserving the router's independent control over remaining experts. Key features include:

- **Near-Lossless Performance**: Maintains almost identical accuracy on code generation, agentic coding, and function calling tasks compared to the full 355B model
- **25% Memory Reduction**: Compressed from 355B to 218B parameters, significantly lowering deployment costs and memory requirements
- **Preserved Capabilities**: Retains all core functionalities including code generation, agentic workflows, repository-scale understanding, and function calling
- **Drop-in Compatibility**: Works with vanilla vLLM - no source modifications or custom patches required
- **Optimized for Real-World Use**: Particularly effective for resource-constrained environments, local deployments, and academic research

## 🚀 Deployment

You can deploy the model directly using the **latest vLLM** (that supports GLM4.7-Flash), no source modifications or custom patches required.

```bash
vllm serve cerebras/GLM-4.7-Flash-REAP-23B-A3B \
    --tensor-parallel-size 4 \
    --reasoning-parser glm45 \
    --tool-call-parser glm47 \
    --enable-auto-tool-choice
```

If you encounter insufficient memory when running this model, you might need to set a lower value for `--max-num-seqs` flag (e.g. set to 64).


## 🧩 Model Creation

This checkpoint was created by applying the **REAP (Router-weighted Expert Activation Pruning)** method uniformly across all Mixture-of-Experts (MoE) blocks of **GLM-4.7**, with a **25% pruning rate**.

### How REAP Works

REAP selects experts to prune based on a novel **saliency criterion** that considers both:
- **Router gate values**: How frequently and strongly the router activates each expert
- **Expert activation norms**: The magnitude of each expert's output contributions

This dual consideration ensures that experts contributing minimally to the layer's output are pruned, while preserving those that play critical roles in the model's computations.

### Key Advantages

- **One-Shot Compression**: No fine-tuning required after pruning - the model is immediately ready for deployment
- **Preserved Router Control**: Unlike expert merging methods, REAP maintains the router's independent, input-dependent control over remaining experts, avoiding "functional subspace collapse"
- **Generative Task Superiority**: REAP significantly outperforms expert merging approaches on generative benchmarks (code generation, creative writing, mathematical reasoning) while maintaining competitive performance on discriminative tasks

### Calibration

The model was calibrated using a diverse mixture of domain-specific datasets including:
- Code generation samples ([evol-codealpaca](https://huggingface.co/datasets/theblackcat102/evol-codealpaca-v1))
- Function calling examples ([xlam-function-calling](https://huggingface.co/datasets/Salesforce/xlam-function-calling-60k))
- Agentic multi-turn trajectories ([SWE-smith-trajectories](https://huggingface.co/datasets/SWE-bench/SWE-smith-trajectories))
