Claims to a first

First large language model in space: unchecked. Hedged by both parties ("believed to be"). Starcloud ran one sixteen months later; the news report of that run words its own first to fit, as the first on a high-powered Nvidia GPU.

Notes

Two parties state this, the developer and the operator of the host computer. It is not counted as confirmed, because the host operator presents the deployment as its own and sells the computer.

Changed

Booz Allen's release, which could not be opened before, was read from an archive capture. The mark is unchanged.
