OpenAI has published a new paper identifying why ChatGPT is prone to making things up. Unfortunately, the problem may be unfixable. When you purchase through links on our site, we may earn an ...

Once a model is deployed, its internal structure is effectively frozen. Any real learning happens elsewhere: through retraining cycles, fine-tuning jobs or external memory systems layered on top. The ...

A new study by the Mount Sinai Icahn School of Medicine examines six large language models – and finds that they're highly susceptible to adversarial hallucination attacks. Researchers tested the ...

The use of artificial intelligence (AI) tools — especially large language models (LLMs) — presents a growing concern in the legal world. The issue stems from the fact that general-purpose models such ...

Large language models turned natural language into a programmable interface, but they still struggle when the world stops ...
