First Light Fusion
An air-gapped sovereign model that reasons over confidential fusion research inside the company's perimeter.
The challenge
First Light Fusion is one of the world's leading fusion-energy companies. Its most valuable asset is unpublished research, simulations, methods, and experimental data, that could never be sent to a third-party AI API. The company needed AI that understood its science without exposing any of it externally.
The solution
Locai delivered a sovereign model post-trained on First Light Fusion's domain and deployed air-gapped inside the company's perimeter, the FLF Coder. With the weights owned by the company and no external connectivity, the model reasons over confidential research with zero data leaving the building.
The outcome
First Light Fusion gained an owned, domain-expert AI capability that respects the absolute confidentiality of fusion R&D, an asset that keeps improving on its own data rather than a rented, general-purpose endpoint.
“We needed AI that could work with our most sensitive science without any of it leaving our control. An owned, air-gapped model was the only acceptable answer.”
