Update: I was wrong about how Opus fixed ts-rust (typescript compiler port to Rust). I thought it picked up from where Astra left off and unblocked whatever Astra was stuck on. It actually decided all of Astra's code was slop, and made an entirely new crate with a from-scratch rewrite. It made more progress in 10 hours than Astra did in 2 weeks 😭

Opus 5.5 got my ts-rust port working in 10 hours, and it has been grinding on performance for the last 24 hours. I've been working on this port on and off for about 4 months. I got to ~35% tests passing with GPT-5.6 Sol, and ~85% with GPT-6 Astra. Both models stalled hard once hitting those numbers, and ran in loops with no meaningful progress for days at a time. I've never had "enough Anthropic tokens" to try a Claude model on a port like this. Opus 5.5 feels practically unlimited, so I threw it a "/goal finish the port and make it faster". I can not believe how quickly Opus unblocked the work Astra was stuck on. It may have made this port an actually viable project. Absolutely mind blown right now.
