Meta maps four new in-house AI chips

SAN FRANCISCO, Calif. — Meta says it is rolling out four new generations of in-house AI chips to power ranking and recommendation systems and future generative AI inference across its apps, a plan confirmed by at least four sources: Meta Newsroom, Reuters, CNBC, WIRED, The Verge, and TimesLive.

• Meta unveiled a roadmap for four MTIA chips: MTIA 300, MTIA 400, MTIA 450 and MTIA 500.
• MTIA 300 is already in production and is used for training ranking and recommendation systems.
• Meta says MTIA 400, 450 and 500 will roll out this year and in 2027 and will be used primarily for generative AI inference workloads.
• The new chips are part of Meta’s MTIA program and are intended to run the company’s internal AI workloads in its data centers.

Additional Details Reported

Meta says the MTIA roadmap is designed for fast, iterative releases, aiming for a roughly six-month cadence as it expands data center capacity. Meta Newsroom and Reuters describe a modular approach that lets newer chips drop into existing rack systems.

Manufacturing and supply chain

Reporting from Reuters and CNBC says Meta is working with Broadcom on parts of the design and using TSMC to fabricate the chips. CNBC also reports that upcoming MTIA 400 racks are optimized for inference and that Meta expects a standard multi-year service life for the hardware.

Inference-first focus

WIRED notes the MTIA 300 is aimed at recommendation-model training, while the MTIA 400, 450 and 500 shift toward inference workloads. The Verge’s summary echoes Meta’s plan to keep later chips focused on generative AI inference through 2027.
