Facebook owner Meta is testing its first in-house chip for training artificial intelligence systems, a key milestone as it moves to design more of its own custom silicon and reduce reliance on external suppliers like Nvidia, two sources told Reuters.
The world’s biggest social media company has begun a small deployment of the chip and plans to ramp up production for wide-scale use if the test goes well, the sources said.
The push to develop in-house chips is part of a long-term plan at Meta to bring down its mammoth infrastructure costs as the company places expensive bets on AI tools to drive growth.
Meta, which also owns Instagram and WhatsApp, has forecast total 2025 expenses of $114bn to $119bn, including up to $65 bn in capital expenditure largely driven by spending on AI infrastructure.

One of the sources said Meta’s new training chip is a dedicated accelerator, meaning it is designed to handle only AI-specific tasks. This can make it more power-efficient than the integrated graphics processing units (GPUs) generally used for AI workloads.
Meta is working with Taiwan-based chip manufacturer TSMC to produce the chip, this person said.
The test deployment began after Meta finished its first “tape-out” of the chip, a significant marker of success in silicon development work that involves sending an initial design through a chip factory, the other source said.
A typical tape-out costs tens of millions of dollars and takes roughly three to six months to complete, with no guarantee the test will succeed. A failure would require Meta to diagnose the problem and repeat the tape-out step.
Meta and TSMC declined to comment.
The chip is the latest in the company’s Meta Training and Inference Accelerator (MTIA) series. The program has had a wobbly startfor years and at one point scrapped a chip at a similar phase of development.
However, Meta last year started using an MTIA chip to perform inference, or the process involved in running an AI system as users interact with it, for the recommendation systems that determine which content shows up on Facebook and Instagram news feeds.
Meta executives have said they want to start using their own chips by 2026 for training, or the compute-intensive process of feeding the AI system reams of data to “teach” it how to perform.
As with the inference chip, the goal for the training chip is to start with recommendation systems and later use it for generative AI products like chatbot Meta AI, the executives said.
“We’re working on how would we do training for recommender systems and then eventually how do we think about training and inference for gen AI,” Meta’s Chief Product Officer Chris Cox said at the Morgan Stanley technology, media and telecom conference last week.
Cox described Meta’s chip development efforts as “kind of a walk, crawl, run situation” so far, but said executives considered the first-generation inference chip for recommendations to be a “big success.”
Meta previously pulled the plug on an in-house custom inference chip after it flopped in a small-scale test deployment similar to the one it is doing now for the training chip, instead reversing course and placing orders for billions of dollars worth of Nvidia GPUs in 2022.
The social media company has remained one of Nvidia’s biggest customers since then, amassing an arsenal of GPUs to train its models, including for recommendations and ads systems and its Llama foundation model series. The units also perform inference for the more than 3 billion people who use its apps each day.
The value of those GPUs has been thrown into question this year as AI researchers increasingly express doubtsabout how much more progress can be made by continuing to “scale up” large language models by adding ever more data and computing power.
Those doubts were reinforced with the late-January launch of new low-cost models from Chinese startup DeepSeek, which optimise computational efficiency by relying more heavily on inference than most incumbent models.
In a DeepSeek-induced global rout in AI stocks, Nvidia shares lost as much as a fifth of their value at one point. They subsequently regained most of that ground, with investors wagering the company’s chips will remain the industry standard for training and inference, although they have dropped again on broader trade concerns.
