Gary Marcus: OpenAI's Astra is Incremental, Not an AGI Revolution
GaryMarcus · x · 2026-08-03
Gary Marcus pushes back against the optimism that AGI is imminent, arguing that OpenAI's recent Astra model is not the dramatic leap forward many fantasized about.
His key arguments include:
- Capabilities matched: Recent models like Fable and Sol demonstrate similar abilities, suggesting Astra is an incremental improvement rather than a revolution.
- Lack of controls: OpenAI failed to include a control group or evidence showing Astra represents significant advances over earlier models on tasks beyond formal verification.
- Naming implications: OpenAI's reluctance to brand Astra as GPT-6 hints they know it isn't a quantum leap across the board.
He emphasizes that pretending every new model is something it's not does not hasten the arrival of true AGI.
