Eleven v3 General Availability

ElevenLabs' Eleven v3 model has exited alpha and is now generally available with improvements to stability, accuracy, and latency compared to previous versions.

Text-to-Dialogue Updates

The Text-to-Dialogue API now supports WAV output formats alongside existing MP3, PCM, and OPUS options:

  • WAV formats available: 8000, 16000, 22050, 24000, 32000, 44100, and 48000 Hz sample rates
  • Pro tier requirement: WAV formats with 44.1kHz sample rate require a Pro subscription or above

Agents Platform Enhancements

Multiple new capabilities have been added for agent developers:

  • Branch management: Agent branches can now be renamed via the Update branch endpoint using the new name field (1-140 characters)
  • Safety controls: Added AlignmentGuardrail type to GuardrailsV1 schema for conversation safety guardrails
  • Turn-taking control: New speculative_turn field allows fine-tuning of agent turn-taking behavior
  • Procedure references: Agent patches now support procedure_refs for referencing reusable procedures
  • Webhook filtering: Response filtering capabilities via response_filter_mode and response_filters fields
  • Debugging: Added raw_error_message field to webhook tool events for improved error visibility
  • Testing: New check_any_tool_matches option allows relaxed tool call matching during agent testing
  • Secrets management: Get workspace secrets endpoint now supports pagination with page_size (max 100) and cursor parameters

Workspace and Permissions Updates

Workspace endpoints now clarify specific permission requirements: group_members_manage for group operations and WORKSPACE_MEMBERS_INVITE for workspace invitations. New permission types have been added to support these granular controls.

SDK Releases

All major SDKs have been updated with the new features:

  • Python SDK v2.34.0: WAV formats, webhook filtering, branch renaming, pagination, speculative turns
  • JavaScript SDK v2.34.0: Same feature parity as Python
  • React/Client SDKs v0.14.0-beta.0: Reduced audio chunk latency from 250ms to 100ms
  • Widget packages: Multiple releases addressing microphone permission handling, UI sync issues, and Tailwind v4 updates

Additional bugfixes address URL streaming in Scribe, agent initialization, and microphone permission recovery across all SDK variants.
