Second-largest US law firm may spend hundreds of millions fine-tuning open-weight Nemotron on its own GPUs

Per FT, Latham & Watkins, the second-largest US law firm ($8.3B sales in 2025), is building its own Nvidia GPU racks and may spend "potentially hundreds of millions of dollars" on in-house legal AI built by fine-tuning Nvidia's open-weight Nemotron 3. About 100 of the firm's 900 tech specialists are on the project.

The CIO cited sensitive client data they won't entrust to any cloud vendor, plus flexibility against mounting consumption costs from major labs.

Commenter adds: big non-tech firms will fine-tune open weights with proprietary data and evals via small internal post-training teams, NDA'd contractors, and post-training startups — similar to what Harvey did.
