OpenAI’s recently launched o3 and o4-mini AI models are state-of-the-art in many respects. However, the new models still hallucinate, or make things up — in fact, they hallucinate more than ...

I visited an airplane model factory in Southern China where airplane die cast models were made. The staff walked me through each process from polishing metal to painting and assembly. Just the pad ...

Just one month later, OpenAI’s newly-announced o3 model achieved a score of 25.2%, which Epoch’s director, Jaime Sevilla, describes as “far better than our team expected so soon after ...

The first two years of the AI boom were all about monolithic large language models (LLMs) such as those OpenAI used to power ChatGPT. But the trick that produced the big intelligence gains in ...

The movable crosslinks are ring-like cyclodextrins, which are threaded on one polymer strand and attached to another, endowing the resulting plastics with increased toughness and durability.

An X-ray binary system composed of a black hole and a star in the process of being consumed turns out to have a third member circling. Unless some unlikely scenarios occurred, the existence of ...
