How Much Cheaper Is GPT-6.1 Sol for Computer Use?

Ari Weinstein says GPT-6.1 Sol is a fifth of the cost of Astra, and a seventh of the cost when the comparison is computer use. He ties that price, and the model's speed, to why the new model is particularly good for computer use. The same keynote recap includes Dots, a personal assistant with computer-use features, and an Agents API so developers can build on the computer use already in Codex and ChatGPT.

The Decisions API is a different, smaller model. It runs inference in parallel and it does not reason, which makes it fast and also less good at long-horizon tasks. Bringing that speed together with the computer-use models is still an open research question.
