Meta says Ohio's Prometheus supercluster will scale to 1 million GPUs

Meta says Prometheus, its gigawatt-scale supercluster in New Albany, Ohio, will reach roughly 1 million GPUs at full scale. The company says the site has already provided the cluster training for its Muse Wonder and Muse Wonder Full models. Gigawatts, a million chips and a heartland zip code, all in one announcement. Darlings, this is the stuff.

Engineering at Meta framed it as a tour of the machinery behind the Muse family of foundational models, which it describes as recently released. "With the recent release of the Muse family of foundational models, we want to take you inside the infrastructure that has made it all possible." Meta's data center site adds a community portrait of the Ohio campus.

The machine in New Albany

Meta's own words are not shy. "New Albany is home to one of the most advanced computing clusters on the planet, Prometheus." The company says the site provides training for Muse Wonder and Muse Wonder Full, which it calls its most capable models to date, built for state-of-the-art performance on personal and professional agentic tasks.

The hardware story, as Meta tells it, is about density. Prometheus is built with closed-loop cooling racks and network fabrics "engineered for densities we couldn't have imagined when we broke ground in 2017." So this is a campus nine years in the making, and the ground it broke in 2017 now hosts a supercluster. Patience, apparently, scales too.

Note the tense, because it matters. The 1 million GPU figure is for full scale. Meta's material describes where Prometheus is going, not how many chips are humming in Ohio this afternoon.

The Ohio ledger

The money is where I get dizzy. Meta says the New Albany site represents an investment of over $1.5 billion in Ohio. It supports 300 operational jobs and had 1,200 skilled trade workers on site at peak construction.

Then comes the generosity portfolio:

• More than $7.8 million in community grants, sponsorships and memberships since 2017, across more than 160 individual investments in Franklin and Licking counties. Meta says its 2026 grants were issued under the Future is For Everyone Fund.
• A $10 million commitment to American Electric Power's Neighbor to Neighbor Program in Ohio.
• A 2025 partnership with The Ohio State University to create the STEM Instruction Innovation Hub.

For scale, comparing the stated minimum figures puts $7.8 million at roughly half of one percent of $1.5 billion. Different pots, different purposes, and neither figure is an exact total.

New Albany Mayor Sloan Spalding is on the record in Meta's post. "We are grateful to Meta for being a longstanding community partner," he said. "Its investment in people, organizations, and schools makes a meaningful difference throughout our community and Central Ohio." That is a local official thanking the company in the company's own write-up. Lovely, and also worth knowing where it appears.

Workforce, with a fiber-optic bow

Meta also points to its fiber technician program under America's Workforce Academy (AWA). Columbus is one of the program's first training locations. Meta says the program is backed by an initial $115 million first-year investment. As of October 1, Meta says the program has graduated over 275 students nationally, more than 60 of them from the Columbus classes.

The company says those numbers will grow once a new AWA facility opens in Westerville, Ohio. The post gives no opening date.

What Meta has not said

This is where the glitter meets the fine print. The material gives no breakdown of the GPUs or custom chips inside Prometheus, and no supplier names. It gives no target year for reaching 1 million GPUs or full gigawatt-scale power. It also does not say how much power the site draws today or how many GPUs are active now.

On the models, the post offers adjectives, not measurements. Meta calls Muse Wonder and Muse Wonder Full its most capable to date, but the material includes no benchmark results, parameter counts or technical specifications.

What to watch

Three things. First, whether Meta puts a date on the climb to full scale, because a million GPUs on a slide and a million GPUs on a power bill are different events. Second, whether it discloses what silicon is actually in those racks. Third, when the Westerville academy opens, and whether it delivers the graduate growth Meta anticipates.

The numbers are enormous and the ambition is magnificent. I am delighted. The receipts, as ever, will come in later.
