OpenAI opens prompt-to-voice to all API customers: describe a custom GPT-Live voice in text, free to create, plus nine new German, French, Hindi, Japanese and Korean voices

On Oct 16 OpenAI made prompt-to-voice generally available to all API customers. Developers describe accent, pitch, timbre and pace in plain text and create a saved custom voice through /v1/audio/voices or the voice Playground, then reuse it in GPT-Live sessions. Creating a voice is free; speech uses regular GPT-Live session billing, with up to 100 prompt-generated voices per organization. OpenAI also added nine natural GPT-Live voices in German, French, Hindi, Japanese and Korean.

Key Takeaways

Generally available to all API customers from Oct 16; no reference or consent recording needed
Creating a voice is free; speaking in GPT-Live and previewing in the Playground use regular session billing (per OpenAI)
Up to 100 prompt-generated voices per organization; optional script_hint of up to 2,000 characters
Nine new natural voices: 3 German, 2 French, 2 Japanese, 1 Hindi and 1 Korean
Limits: prompt voices work only with GPT-Live, not TTS, Realtime or Chat Completions; voice creation is not Zero Data Retention compatible

OpenAI ships GPT-Live-1.1 and GPT-Live-1.1 Quip as the new voice models in ChatGPT, Codex and dots; API coming soon

On Oct 15 OpenAI rolled out GPT-Live-1.1 (successor to GPT-Live-1) and GPT-Live-1.1 Quip (successor to GPT-Live-1 mini), full-duplex voice models that become the default voice for Plus-and-up users in ChatGPT Voice, Codex and dots. New voices cover French, German, Hindi, Japanese, Korean and Mexican Spanish, accents are more natural and the constant 'checking...' filler is reduced. Rolling out to all users; API coming soon. The system card reports statistically significant regressions in four synthetic safety categories.

Key Takeaways

Two tiers: GPT-Live-1.1 replaces GPT-Live-1 and GPT-Live-1.1 Quip replaces GPT-Live-1 mini; 1.1 is default for Plus+ including Codex and dots, Quip for everyone else
New Live voices in 6 languages (French, German, Hindi, Japanese, Korean, Mexican Spanish) plus Bubbie in English; fewer repetitive 'checking...' fillers while searching
Full-duplex: listens and speaks continuously, handling pauses, interruptions and pace changes; the system card describes GPT-Live as a two-model system that delegates hard work to thinking models
System card: parity on production voice evals; statistically significant regressions on sexual, mental health, emotional reliance and gore synthetic evals vs GPT-Live-1
Rolling out to all users today; API 'coming soon' with no published price, model ID, latency or WER figures yet

Pydantic AI v2.51.0 (2026-09-25) adds OpenAILiveModel for OpenAI GPT-Live, exposes context_window_used on realtime sessions, tightens Gemini Live id/affective-dialog checks, and raises UserError for forced realtime tool_choice on OpenAI/Azure/xAI. PyPI pydantic-ai 2.51.0 is live.

Key Takeaways

Shipped: GitHub v2.51.0 = PyPI pydantic-ai 2.51.0; docs pydantic.dev/docs/ai
Realtime: OpenAILiveModel for GPT-Live; context_window_used on sessions from GPT-Live ratio or response usage
Compat: match dated gemini-3.8-live ids; reject google_affective_dialog at connect; RealtimeError on Gemini Live close codes
Safety: UserError for forced realtime tool_choice on OpenAI/Azure OpenAI/xAI
Perf: cache agent graph across Agent.run(); skip task group for single-child fan-out
