I’m currently using Grok 4.5 99% of the time now for both planning and tasks.
The fact that I don’t have to switch out to a cheaper model to do tasks means there is less context window model switching and faster speed.
Feels incredible.
We had a team of agents rebuild SQLite from its 835-page manual.
It created a replica in Rust which passed 100% of a held-out test suite.
Interestingly, cost varied 15x depending on which model mix we used.
