Internal memo: use Astra 6 computer use on ultra mode for knowledge work
The author calls ChatGPT Astra 6 with computer use on ultra mode the first step-change in capability since Claude Code, while warning users never to give up their own understanding of what the model is doing.
internal memo: If you have not yet, please use ChatGPT Astra 6 with computer use on ultra mode if you are doing knowledge work tasks. This is the first time since Claude Code in Dec 2026 that I've felt a step function change in capabilities - ability to use AI just operates entirely differently. These are expensive background tasks (many run for 1hr+), but completely fundamentally change ability to use models. Warning: never ever ever give up your understanding to these models -- if you don't understand what it's doing, or why the outcome is the right one, you are setting yourself up for long term failure.
