haiku 5.5 is an absolutely insane model release . i'd been starting to make frequent and good use of luna as a massive fanout machine, just having a reasonably smart agent look at and modify like every single one of ten thousand files for under $100 total. i really think people underestimated how insanely cheap that kind of capability is and how much it can do, it can let a smarter orchestrator model finish in 20 minutes the kind of thing that would otherwise be straight up impossible or involve days of expensive inference and it writing crazy heuristic software to avoid actually ingesting all the bytes. but now instead of luna i can use something that's not just mildly capable, but genuinely able to end to end build small things, make its own tools, do local refactors I trust, so on so on.

it's fucking amazing man
