Is GPT-Live (ChatGPT Voice) Down?

**ElevenAgents gained two new tools in the week of 2026-10-06: Architect (alpha, 10/06), a built-in expert that diagnoses agent failures from transcripts and drafts tested fixes, and synthetic voice detection (10/09), which flags AI callers in the first seconds of a call -- enterprise-only for now. ElevenCreative added Brand Kit (10/09).** **Two days after the v4 launch, ElevenLabs closed a $300M employee tender at a $22B valuation (2026-09-30), double its February Series D, with enterprise now 55% of revenue -- and the pricing page is running v4 launch promos (extra v4 credits on Creator plans and above, see the Oct 2 note).** **Eleven v4 and Eleven v4 Turbo launched 2026-09-28 -- a fourth-generation voice model on an entirely new architecture**, ranked #1 on Artificial Analysis' Provider Voice Arena and preferred by ~75% of listeners in blind head-to-head tests against Cartesia Sonic 3.6, Inworld TTS-2 and Google's Gemini 3.8 Flash and Flash-Lite TTS; v4 Turbo answers with a ~100ms median inference latency (~150ms to first speech over WebSocket) and is co-optimized with ElevenAgents. Both cover 90+ languages, follow inline audio tags like [laughs] or [phone buzzing] more accurately, clone voices with better speaker similarity, and are live now in ElevenAgents, ElevenCreative and the API (Text to Dialogue). Eleven v3 becomes the previous generation. The 2026-09-10 Universal Music Group licensing deal and CLI v1 (8/24) still stand.

xAI's standalone voice APIs. **Grok Voice Transcribe 2.0 shipped 2026-09-18** -- xAI calls it twice as accurate as 1.0 at the same $0.10/hr batch and $0.20/hr streaming, ranks it first for accuracy among 32 streaming models on Artificial Analysis, and has already made it the default STT model; **1.0 is being retired in the coming weeks, so pin grok-voice-transcribe-1.0 if you need it**. **PRICE CORRECTION: text-to-speech is $15.00 per 1M characters on xAI's live rate card (verified 2026-09-21), not the $4.20 this page carried since April.** Speech-to-speech agent $0.08/min, 26 flagship voices, ~1-minute voice cloning, no-code Voice Agent Builder

Microsoft's in-house expressive TTS line. **MAI-Voice-2.1 and MAI-Voice-2.1-Flash launched 2026-10-01: 23 languages and 26 locales with one voice that keeps the same speaker and a native accent across languages, voice cloning from a few seconds of reference audio with consent guardrails, priced at $22 per 1M characters for 2.1 and $15 per 1M characters for Flash, which generates 45 seconds of audio at 150 ms end-to-end latency and is pitched at voice agents alongside MAI-Transcribe-2-Streaming.** These supersede **MAI-Voice-2 (Build, 2026-06-02)**: 15 languages, emotion tags, zero-shot cloning from a 5-60 s clip, preferred over MAI-Voice-1 72% of the time. Microsoft also shipped a MAI-Voice-2-Flash and MAI-Image-2.5-Pro in July that this page had not recorded -- see the Oct 2 note.
