Starting today, all paying API customers have access to GPT-4. We recommend users adopt the Chat Completions API, as it now accounts for 97% of our API GPT usage. The GPT-3.5 Turbo, DALL·E, and Whisper APIs are also generally available. We are working on enabling fine-tuning for GPT-4 and GPT-3.5 Turbo.
