- Throughput: Modern CPUs handle 4-bit matrix operations efficiently
- Accuracy: Minimal degradation compared to full precision (typically <1% on benchmarks) - llama.cpp: Purpose-built for CPU inference, handles quantized models natively
- FastAPI: Async Python framework, minimal overhead, production-ready
- AWQ format: Smaller than GGUF, faster loading, better CPU performance - Go to DigitalOcean
- Create a new Droplet
- Choose: Ubuntu 22.04 LTS
- Select the 32GB Memory / 32 vCPU plan ($384/year, billed monthly at $32)
- Choose a datacenter close to your users (latency matters)
- Add your SSH key
- Click "Create Droplet"
