T3 Code Slashes Thread Load Time 72x
Theo shared a T3 Code performance sprint showing 27 changes in four days, including a 72x improvement opening 41,000-item threads and major gains across mobile, networking, and reasoning previews. He credits Claude Fable 5.2 for helping drive the overnight work.
This is a strong example of AI coding value showing up in product polish and iteration speed, not just generated code. The results are impressive, though they remain self-reported and workload-specific.
- –41,000-item thread loading fell from 2,230ms to 31ms.
- –Earlier-turn loading improved 14x, while mobile launch size dropped from 5.2MB to 0.7MB.
- –Slow-3G reconnects improved 3.6x, making remote agent monitoring more practical.
- –T3 Code’s open-source, multi-agent control surface benefits disproportionately from faster navigation and lower mobile overhead.
- –Fable 5.2 appears to be an acceleration layer for engineering work, not the product update itself; independent profiling would validate the claimed gains.
