TechnologyToday's huge AI models are composed of several billion numbers known as weights and changing just one of them can destroy their ability to function, leading to gibberish output 26 November 2024 The output of AIs is controlled by the interactions of huge networks of nodes or weightsshulz/Getty ImagesAn artificial intelligence model can be made to spout gibberish if a single one of the many billions of numbers that compose it is altered.Large language models (LLMs) like the one behind OpenAIs ChatGPT contain billions of parameters or weights, which are the numerical values used to represent each neuron of their neural network. These are what get tuned and tweaked during training so the AI can learn abilities such as generating text. Input is passed through these weights, which determine the most statistically likely output.
