Enterprise code base (500k+ LOC) for an intensive refactor focusing on optimization of core components that have impact on the majority of the stack. Fable 5.1? Astra? Opus 5.5 (w/ Fable as advisor)? I use all 3 and I’m trying to juggle the most sensical option to begin this effort with. I lean toward Fable 5.1. I know this information isn’t comprehensive enough to make the best decision - I’m asking purely on vibes here (think suspected recent Opus 5.5 nerfs). What would you use? submitted by /u/drussell024
