OpenAI announced updates to its API models, including function calling capabilities, enhanced steerability, longer context, and reduced prices.

The function calling feature allows developers to describe functions to gpt-4-0613 and gpt-3.5-turbo-0613, which can intelligently output a JSON object containing arguments to call those functions.

This makes it easier to connect GPT's capabilities with external tools and APIs. New versions of GPT-4 and GPT-3.5-turbo models have been released, which include these updates, while the initial versions released earlier in the year will begin the deprecation process. OpenAI has also significantly reduced costs for their text-embedding-ada-002 model by 75% and for input tokens for gpt-3.5-turbo by 25%.

These updates underscore OpenAI's commitment to improving developer experience and driving efficient, cost-effective AI innovation.
