Meta is pushing forward with plans to manufacture its next-generation AI chip, codenamed “Iris,” as part of an aggressive buildout. The move represents one of the most ambitious in-house silicon plays in Big Tech, placing Meta alongside Apple, Google, and Amazon in the growing club of companies that decided buying chips from Nvidia wasn’t enough.
The chip roadmap taking shape
Iris is the codename for Meta’s MTIA 400, the fourth generation in its Meta Training and Inference Accelerator series. By March 2026, the chip had already completed lab testing, clearing a critical milestone on its path to data center deployment.
Meta’s predecessor chip, the MTIA 300, is already in production. The company has mapped out four new chip generations, spanning MTIA 300 through MTIA 500, all slated for deployment by the end of 2027, a cadence approximating a new chip generation roughly every six months.
The performance numbers across these generations are notable. Meta is targeting a 25x increase in compute FLOPS and a 4.5x improvement in high-bandwidth memory (HBM) bandwidth.
