    One traditional enterprise goal of 40% utilization was to cover DR/failovers, so one region could take on 100% of traffic from another, with 20% headroom.

    I'm curious about the granularity of contracts around granting/selling excess capacity. Are they short term? Can the owner evict those workloads (with a penalty)?

      This is a cool idea—I know from snooping on sumbit scripts and node utilization on the HPC that I use at my institution that most submissions leave some compute on the table (and many of them are egregiously bad). I'd probably vote in favor of sending every submitted sbatch script through an LLM (at least for everyone else, I'd would prefer tuning my own usage myself :) ).

      Presumably the underlying model here is also an LLM? To what degree is it "fine-tuned", or is it just given a set of tools to build a good picture of cluster usage?

        I have been working on open source traffic shaper for agents. I think it may help you better with prediction if requests don’t stampede you

          > Datacenters run at roughly 30% to 40% effective utilisation

          I wonder what is stopping datacenters from passing this benefit to customers by launching better tuned plans. For example, t series EC2 instances on AWS.

            Isn’t the fact that you just referenced it indicate that they do?

            I feel like it’s probably just complexity.

            Different workloads benefit from specific types of optimisations.
