Music Finetunes API ships; agent defaults reversed

Music

• Music Finetunes API: Added API support for managing Music Finetunes. Five endpoints let you create a Finetune from uploaded audio, list accessible Finetunes, retrieve training status, update metadata and visibility, or delete a Finetune. Music generation SDK methods now expose finetune_id and finetune_strength (number, greater than 0 and at most 2; default 1).

ElevenAgents

• Resolve external conversation references: Added GET /v1/convai/conversations/resolve to resolve a Slack message URL or Zendesk ticket URL to a conversation. Requests require agent_id and reference query parameters (strings).
• Query agent knowledge bases: Added POST /v1/convai/agents/{agent_id}/knowledge-base/rag-query for read-only RAG queries against an agent's knowledge base. The request requires query (string), accepts optional branch_id (string), and returns ranked chunks with document, chunk, text and vector-distance metadata. This endpoint is excluded from generated SDKs.
• Knowledge base content formats: Knowledge base file, text and URL responses add optional content_format (html | markdown, default html).
• Agent voice configuration: TTS override schemas add optional client-overridable model_id (TTSConversationalModel). The default for enable_phoneme_tags changes from false to true.
• Faster backup LLM cascade: The default cascade_timeout_seconds changes from 8 to 4 seconds. The allowed range remains 2–15 seconds.
• Tool parameter value sources: Object tool parameters can now use dynamic_variable, constant_value or is_omitted, matching existing scalar and array controls. Constant schema overrides now accept arbitrary arrays and objects.
• Full-response guardrails: Custom guardrails add optional evaluate_full_response_only (boolean, default false) to evaluate the complete non-TTS response once. This option requires blocking mode.
• Twilio call recording: Telephony call configuration adds optional twilio_call_recording_enabled (boolean, default false). Recordings are stored in the connected Twilio account and the setting is ignored by other providers.
• Widget file-upload text: Widget text configuration adds optional labels and error messages for attaching and removing files, upload failures, unsupported types, oversized files, file-count limits and the typing indicator.
• Knowledge base sync status: Knowledge base file responses add optional auto_sync_info and refresh_status (FileRefreshStatus). Folder responses add required document_count (integer), a recursive count of non-folder documents capped at 1000.
• Conversation text search filters: Text search conversation messages adds optional exclude_statuses and termination_reasons array query parameters.
• LLM options: Agent LLM configuration adds gpt-5.6-sol, gpt-5.6-terra and gpt-5.6-luna. LLMReasoningEffort adds max.
• WhatsApp typing indicators: WhatsApp account request and response schemas add optional enable_typing_indicator (boolean).

Speech to Text

• Single-use batch authentication: Convert speech to text adds optional token (string) as an alternative to API key or bearer authentication. Create the single-use token with POST /v1/single-use-token/batch_scribe; it expires after 15 minutes.
• Realtime model and language options: Realtime Speech to Text adds scribe_v2_realtime_turbo and scribe_v2_realtime_lite model IDs, plus secondary_languages for additional transcription languages.
• Realtime client reliability: @elevenlabs/client now reports microphone setup and malformed server errors through RealtimeEvents.ERROR, releases microphone resources after setup failures and connection closure, and drops late microphone frames after socket teardown.

Text to Speech

• Archived pronunciation dictionaries: List pronunciation dictionaries adds optional include_archived (boolean, default true).

Workspaces

• Webhook event subscriptions: Update workspace webhook requests add optional events (WorkspaceWebhookEventType[]) with voice_library_removal_notice, speech_to_text and agent_qa. Webhook responses can return the subscribed event list.
• Usage analytics dimensions: Get workspace usage adds surface and actor to the group_by values.
• Clear service account limits: Update service account API key accepts character_limit: "clear" to remove a monthly character limit, alongside "no_update" and integer values.
• Alerting webhook references: Alerting webhook notifier schemas now identify a workspace webhook with required webhook_id (string) instead of embedding url, method and headers.
