AI turned game exploration into models with checked proofs

On two impossible game levels, the framework produced checked proofs in all six runs; two models with coding tools produced none in twelve comparison runs.On two impossible game levels, the framework produced checked proofs in all six runs; two models with coding tools produced none in twelve comparison runs.

A proof shows when predictive models learn matching patterns

Paired views of one scene needed 42 times fewer training samples than predicting the next piece of text to match alignment on the same text collection.Paired views of one scene needed 42 times fewer training samples than predicting the next piece of text to match alignment on the same text collection.

In particular, recent studies have examined whether LLMs can accurately reason about causation.

This paper examines how and why LLMs perform well on CLadder, a dynamic benchmark for evaluating causal reasoning, and what can be inferred from the results.
