Plain language
One of OpenAI's AI models, used here as a driver in a car-control test.
As stated in the literature
OpenAI GPT-5.6 variant codenamed Sol, evaluated inside the Codex agent application.
Also called: Sol
Why it matters: Naming the exact model variant and the application it ran inside matters because results from a model wrapped in one agent harness do not transfer to the same model used bare.
For example, in one test this model was given the steering and speed controls of a real car on a closed course and asked to drive it.
Heard on the show
