Developer theo reports a TypeScript→Rust port he worked on for 4 months: GPT-5.6 Sol reached 35% test pass rate, GPT-6 Astra 85%, both stalling in loops for days. With Opus 5.5's practically unlimited tokens, a single "/goal finish the port and make it faster" quickly unblocked what Astra was stuck on; the port now works and Opus has been grinding on performance for 24 hours straight. He says it may make the project actually viable.
