About this offering: Retired: OpenAI shut gpt-4o-audio-preview down on 2026-05-07 and recommends gpt-audio-1.5 instead. It was OpenAI's first audio-native GPT-4o model, taking and returning audio through the Chat Completions API, and was billed per audio token rather than per character, so it can't be compared directly with per-character TTS prices.
