The large language models behind AI chatbots are developing so rapidly that after eight months, a model only needs half the computing power to hit the same benchmark score – which is much faster than the rate at which computer chips improve.

The artificial intelligence models behind popular chatbots developing faster than Moore’s law, a measure of how quickly computer hardware performance increases. That suggests the developers of AI systems, known as large language models (LLMs), are becoming smarter at doing more with less.
