Change log

  • — Updated from Eleven v3 to Eleven v4 (released 2026-09-28): eleven_v4 (10,000-char requests, Text to Dialogue API) plus eleven_v4_turbo (real-time, ~100ms median inference, Text to Dialogue WebSocket), 90+ languages, better voice cloning. ElevenLabs' models page now marks eleven_v3 as previous generation; on 2026-10-05 the ElevenAgents default moved to eleven_v4_turbo.
  • — Dropped Turbo v2.5 from purpose and strengths — ElevenLabs' models page now marks Eleven Turbo v2.5 and Turbo v2 as deprecated, 'outclassed by Flash models', with eleven_flash_v2_5 as the replacement. Eleven v3 itself verified current; no v4 exists.
  • — Link fix: promoted the models overview (elevenlabs.io/docs/overview/models) to the primary docs link. The API reference was the only docs link, and it does not enumerate models — which made it a poor verification source. Kept as a secondary link.
  • — Updated from Multilingual v2 to Eleven v3 (GA 2026-02-02), 70+ languages. Multilingual v2 remains available but is no longer the flagship.
  • — Initial entry.
