Google TPU Developer Hub Reviewed: Performance vs. Practicality

Google's TPU Developer Hub aims to simplify ML development on TPUs with centralized docs, notebooks, and migration guides. TPU v5e offers ~4.6x throughput gain over A100 for large LLMs at $2.20/h per chip, but requires at least 256 chips for models over 70B parameters. The platform's value depends on deep Google Cloud integration, posing challenges for multi-cloud environments.
