What stands out
What its maker marketed at launch, and what people found later, each with its source.
Low-latency preset-voice TTS
tts-1 optimised for real-time synthesis; tts-1-hd for higher quality at twice the price.
Notes
Deprecated 2026-10-01 together with tts-1-hd and the gpt-4o-mini-tts snapshots: removal from the API on Jan 6 2027, replacement gpt-realtime-2.1-mini (https://developers.openai.com/api/docs/deprecations). Earlier note: no longer shown in the models overview; gpt-4o-mini-tts is the current, instruction-steerable replacement.
