On Thursday, OpenAI announced that all paying API customers now have access to the GPT-4 API. It also introduced updates to chat-based models, announced a shift from the Completions API to the Chat Completions API, and outlined plans for deprecation of older models. In a move to distance itself from older GPT-3-style models, OpenAI has also opted to begin retiring “Completions API” models in favor of newer Chat Completions API models. Since its March launch, OpenAI says that its Chat Completions API models now account for 97 percent of OpenAI’s API GPT usage.
I’m still cautiously optimistic about GPT.
