OpenAI is upgrading its text-generating models while reducing pricing. OpenAI announced the release of new versions of GPT-3.5-turbo and GPT-4, the latter being its latest text-generating AI, with a capability called function calling. As OpenAI explains, function calling allows developers to describe programming functions to GPT-3.5-turbo and GPT-4 and have the models create code to execute those functions.
