abstract: MTIA 400 is Meta's fourth-generation custom AI chip, optimized for both AI model training and ad-serving inference. It represents a strategic consolidation of compute workloads previously split across different hardware platforms. The chip is not yet deployed at scale; it remains in internal evaluation and benchmarking phases.
