I imagine some scenarios where you're throwing a big data set at an LLM could add up quickly.

"Check all of Confluence for outdated and conflicting info"

"Review all the legal contracts over the past 10 years"

"Evaluate the source code in all our dependencies for vulnerabilities"

All of those would be fairly straight forward for a single person to kick off without thinking about the data set size. Especially if they have Claude set to Opus 4.7 x high effort for everything.

Even someone saying something like "rewrite the 25 year old Java monolith in rust" as a PoC and leaving it running in the background for a week
