    In addition to commoditizing models and compressing margins, open weight pushes competition to physical infrastructure: power, data centers, and chips, which they are moving faster on in at least the first two. @fluidstack is fighting back: join us fluidstack.io/jobs

    Why does China keep releasing open-weight models? Well, releasing frontier open-weight models commoditizes the closed-weight models of OpenAI and Anthropic, which challenges their businesses, which ultimately causes the splintering of their most valuable asset, their teams.

    One picture, from the badge reader to the login. Fluidstack watches the physical and the digital as a single connected story: the systems that run the facility, the networks that move the data, the people who walk through the door, the identities that sign in - all aware of each

    2/ Most security programs stitch those worlds together after the fact. Ours was built as one from the start.

    3/ What we are building toward is more ambitious still: a security program sophisticated enough to defend the infrastructure behind the most consequential technology of this decade - defensive depth that holds at every layer of the pyramid of pain, from the indicators an

    1/ How do you hide a datacenter from a satellite?

    3/ Forecasters writing about the next decade of AI have extended that logic in published thought experiments: covert datacenters disguised as heavy industrial plants, or built underground with exotic cooling to hide their thermal signature from satellites.

    4/ Whether those scenarios ever materialize, the assumption underneath them is the right one: actors with that patience and resourcing should be presumed to be probing frontier AI infrastructure today. We operate on that assumption.

    1/ The adversaries most capable of reaching frontier AI infrastructure have practically unlimited time, money, and technical depth. The question is not whether they will try - it is whether you can out-adapt them.

    5/ There is another layer that is easy to miss: the systems producing the evidence are themselves part of the attack surface. A capable adversary may not need to defeat a control if they can make the control report that everything is normal.

    6/ The absence of noise is not proof that nobody is in the room - and it is not proof that the alarm is still connected.
