Yeah, the captions are in the right arena but fundamentally wrong. In the baseball picture it recognizes the ball, pitcher, and the act of throwing, but calls the action wrong. Its object recognition and pattern matching are excellent, but higher level thinking and self-correction are totally absent.

Which is exactly where GPT, etc., are capping out. Its easier to see the flaws in this one because its more general, so spread out more thinly.

To get to the next step (easy to say from an armchair!), these models need a sense of self and relational categories. Right now a 5-year old can tell a more coherent story than GPT. Not more sophisticated, but it will have a central character and some tracking of emotional states.

I really think this is due to the very limited number of parameters in GATO: 1.2B vs. 175B for GPT-3. They intentionally restricted the model size so that they could control a robot arm (!) in real time.

The places where I personally see GPT-3 getting hung up on higher level structure seem very related to the limited context window. It can't remember more than a few pages at most, so it essentially has to infer what the plot is from a limited context window. If that's not possible, then it either flails (with higher temperatures) or outputs boring safe completions that are unlikely to be contradicted (with lower temperatures)
