For us, it would be for SRE stuff. We have agents reviewing traces and logs, and inspecting system behavior daily - for non obvious problems, not surfacing in metrics. When we hit an issue, we use the /fast mode to triage, propose a fix and then build and deploy. It is trivial amount of money all things considered, and I'd happily authorize a 100x spend for when we have a prod outage on a mission critical service.
When you think about it, it would still be dirt cheap compared to normal way of doing things. In the old days, if you had an outage on a serious user facing system, you'd wake up people across various timezones, wake up their managers and scramble to find the root cause, identify a solution, brainstorm on possible side effects of a fix, and then rush to build it and deploy. This cycle would involve, sometimes, dozens of people, for, say, 10 man hours each. So lets make it 120 man hours per serious outage, and lets assume and average of $100 per hour - so, $12,000 per a serious outage fixed under a day, counting conservatively and not including the costs of the actual outage.
I'd guess the pricing for those ultrafast, very energy inefficient and hardware heavy models will be competing with that. Its going to be possible to get a fix out in 30 minutes, 10 of which will be tests, 5 will be the deploy, and the remaining 15 will be some unlucky guy trying to keep up with the super fast model throwing a 50 "load-bearing deferrals earning their keep" per minute :-)
The pricing on those things is competing with costs to run entire departments. I'd, for one, imagine offshore ops teams will be a thing of the past in under a year, since one gets way better initial response to anything from a model, given right setup, esp. on codebases that have been built from the ground up with agentic coding - so with good documentation and effective test coverage baked into repos.
