## Buyer Intent Signals
Problems: CPU-based Inference: Utilizing general-purpose CPUs for inference tasks, which is often slower and less cost-efficient for large models.
Solutions: cheapest way to train LLMs on AWS | AWS Inferentia2 benchmarks | best instance for deep learning inference | Aws Trainiuminferentia2 specs | NVIDIA GPUs (A100/H100): The industry standard for AI training and inference, offering high performance but often at a higher cost and lower availability. | Google TPU: Alternative specialized AI accelerators from Google Cloud, requiring migration to a different cloud ecosystem.
