> During early testing, Stripe reported that Fable 5, [...] in a 50-million-line Ruby codebase, the model performed a codebase-wide migration in a day that would otherwise have taken a whole team over two months by hand.

EDIT: I misread. This comment previously talked about 50 million lines being migrated. Instead, in a 50M LOC codebase, one specific codebase-wide migration was done.

Very impressive, but obviously not on the order of a whole-codebase migration

They do not claim to have migrated 50 million lines of Ruby. Simply that some migration took place in such a codebase.

		Converted all the tabs to spaces? :-) You are right, this is not a rewrite like the Bun case. The real news is, at 50M LOC, it is able to handle and do _something_ coherent.

Ok, so Stripe migrated their 50MLOC codebase from Ruby to Rust? Because that's what Bun did.
