Meta unveiled four in-house AI chips in its MTIA family and said the MTIA 300 has been deployed while MTIA 400, 450, and 500 will follow about every six months.
Yee Jiun Song, vice president of engineering, told CNBC the chips give Meta more diversity in silicon supply and help insulate the company from price changes.
Meta said MTIA 300 is being used to help train smaller models that support ranking and recommendation tasks across Facebook and Instagram, and Song said MTIA 400 through 500 target generative AI inference rather than training giant LLMs.
Meta said MTIA 400 has completed testing, and that one rack will include 72 MTIA 400 chips, while MTIA 450 and 500 are slated to enter service in 2027.
The chips are manufactured by Taiwan Semiconductor Manufacturing Co. (TSMC) and will include more high-bandwidth memory, which Song said Meta believes it has secured for its planned buildout despite industry shortages.
Meta has also signed large deals to buy millions of Nvidia GPUs and up to 6 gigawatts of AMD GPUs over multiple years as it expands data center capacity in the US.
Meta said most of the engineers who worked on the silicon are based in the US and that 26 of its 30 operational or planned data centers are in the country.
