    First Light Fusion

    An air-gapped sovereign model that reasons over confidential fusion research inside the company's perimeter.

    Air-gapped deployment, no external connectivity
    Model post-trained on confidential fusion research
    Weights and IP owned by First Light Fusion
    Domain-expert reasoning over proprietary science

    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 Its most valuable asset is unpublished research, simulations, methods, and experimental data, that could never be sent to a third-party AI API.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.”
