"more than twice the speed" is underselling Haiku tbh built a way to directly compare Sonnet v Haiku 4.5 and it's roughly 3.5x faster, but the UX feels SO much better because Haiku stays inside the "flow window". obviously end to end latency varies a lot so Ant can't report a real number without production usage but you should try heads up comparisons

At a past company, the head of engineering and the principal engineers decided to break our Ruby on Rails application into a Go microservices mesh. They created very detailed design documents and architecture diagrams. They went all out and used Kubernetes, gRPC, service templates, the whole shebang. The whole senior engineering leadership came from Amazon, where they were used to each team owning a distinct service. They tried to apply that model directly. But our issues were with code ownership and poor domain modeling. The entire application could have run on just a handful of EC2 instances. What was the result? Five years later, 70% of the application is still running on the Ruby on Rails monolith. Never completed the migration. But now they have to maintain two systems. None of the original leadership works there anymore.
