Overview
The simplest way to leverage ATLAS is through inference-only integration. This approach uses pre-trained teacher models to enhance any student model’s performance without requiring training infrastructure.Prerequisites
- Python 3.8+
- PyTorch 2.0+
- Transformers library
- 16GB+ GPU memory (or CPU with sufficient RAM)
- Pre-trained ATLAS teacher model
Installation
1
Install Dependencies
Install the minimal requirements for inference:
For CPU inference, install PyTorch without CUDA:
2
Download Teacher Models
Choose and download a pre-trained teacher model:
Models are ~16GB each. Ensure sufficient disk space and bandwidth.

Out of Memory Errors
Out of Memory Errors
Problem: CUDA out of memory during inferenceSolutions:
- Enable 4-bit quantization:
load_in_4bit=True
- Use CPU offloading:
offload_folder="./offload"
- Reduce batch size:
batch_size=1
- Use smaller models or single model at a time
Slow Inference Speed
Slow Inference Speed
Problem: High latency for responsesSolutions:
- Enable Flash Attention:
use_flash_attention=True
- Use GPU instead of CPU
- Cache guidance for repeated queries
- Consider selective enhancement for simple queries
Poor Enhancement Quality
Poor Enhancement Quality
Problem: Enhanced responses not significantly betterSolutions:
- Verify correct teacher model for task type
- Check student model compatibility
- Adjust temperature and top_p parameters
- Ensure sufficient context length
