GPT-6 Astra drove a real Toyota Corolla through a cone course, Claude and Grok dropped out after a few meters
Three computer scientists from the San Francisco area, working as DrivingBench, connected GPT-6 Astra, GPT-5.6 Sol, Claude Fable 5.1 and Grok 4.6 to a rented Toyota Corolla and handed them the steering wheel, gas and brake, 404 Media reports. Only GPT-6 Astra completed the cone course in a parking lot; the other models drove a few meters. To get the models to agree to drive at all, the team had to call the real parking lot a "sandbox."
