This is a quantized version of INTELLECT-3-REAP-50, a Router Expert Activation Pruned (REAP) Mixture of Experts (MoE) model. This version has been compressed to FP8-Dynamic precision using the llmcompressor library to optimize it for high-performance inference with a reduced memory footprint.

Key Features

Quantization: FP8-Dynamic (activations and weights).
Architecture: REAP-optimized MoE based on GLM-4.
Efficiency: Designed to run on modern GPUs (NVIDIA Ada Lovelace and Hopper architectures) with significant VRAM savings.
Algorithm: One-Shot Post-Training Quantization (PTQ).

REAP Optimization

REAP (Router Expert Activation Pruning) enhances MoE efficiency by pruning the activation of experts through a specialized routing mechanism. By combining this architecture with FP8-Dynamic quantization, the model achieves a balance between the high parameter count of MoE and the low latency required for production environments.

Installation

To run this model, ensure you have the latest transformers and torch versions installed:

bash

pip install torch torchvision transformers typing_extensions llmcompressor

Usage Example

python

from transformers import AutoTokenizer, AutoModelForCausalLM

MODEL_ID = "Akicou/INTELLECT-3-REAP-50-FP8-Dynamic"

model = AutoModelForCausalLM.from_pretrained(
    MODEL_ID,
    device_map="auto",
    torch_dtype="auto",
)
tokenizer = AutoTokenizer.from_pretrained(MODEL_ID)

prompt = "Write a technical summary of how FP8 quantization improves LLM inference."
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

output = model.generate(**inputs, max_new_tokens=150)
print(tokenizer.decode(output[0], skip_special_tokens=True))

Usage on Runpod

Quantization Details

The model was quantized using the following llmcompressor configuration:

Targets: Linear layers.
Scheme: FP8_DYNAMIC.
Ignored Layers: lm_head.
Calibration: Performed with oneshot algorithm.

Limitations

Hardware: Native FP8 support requires NVIDIA Blackwell, Hopper, or Ada Lovelace GPUs.
Precision: While dynamic scaling minimizes loss, slight accuracy deviations may occur compared to the original BF16 weights in highly niche benchmarks.
