Now tech companies are starting to embrace smaller A.I. technologies that are not as powerful but cost a lot less. And for many customers, that may be a good trade-off. On Tuesday, Microsoft introduced three smaller A.I. models that are part of a technology family the company has named Phi-3. The company said even the smallest of the three performed almost as well as GPT-3.5, the much larger system that underpinned OpenAI’s ChatGPT chatbot when it stunned the world upon its release in late 2022.
The smallest Phi-3 model can fit on a smartphone, so it can be used even if it’s not connected to the internet. And it can run on the kinds of chips that power regular computers, rather than more expensive processors made by Nvidia.
