When enabled, supported models can execute multiple tools in one turn. - **Agent models**: Added `gpt-6-astra` to the agent LLM options. - **Alerting**: Agent alerting now supports Slack channels alongside PagerDuty and webhook notifiers. - **Phone number search**: Added a cursor-paginated phone number endpoint with filters for provider, outbound support, assigned agent and branch, label and phone number. ### Image and video - **GPT Image 2.5 models**: [Image generation](/docs/api-reference/flows/image/create) now supports `gpt-image-2.5-flare` and `gpt-image-2.5-sunburst`. Both models accept up to 10 reference images, quality levels through `max`, 14 fixed aspect ratios plus `auto`, and 1K, 2K or 4K output. ### Speech Engine - **Cascade timeout**: Speech Engine create and update requests now accept `cascade_timeout_seconds` (number, 2–15, default `4`) to control how long ElevenLabs waits for an upstream speech engine before retrying. ### Text to Speech - **Multi-context turn boundaries**: The `is_final_audio_for_turn` marker is now emitted after every buffered byte for that turn, including MP3 and Opus output. Clients can use the marker as an exact turn boundary without switching to PCM. ### SDK releases #### JavaScript SDK - [v2.69.0](https://github.com/elevenlabs/elevenlabs-js/releases/tag/v2.69.0) - Added `transcriptEdit` to the realtime Speech to Text wrapper, with edited text delivered through `edited_transcript` events. Fixed Speech Engine JWT verification for API keys with data residency suffixes. Added `phoneNumbers.listV2` and Flows template methods to list and get templates and list, create and get runs. Regenerated clients and types for GPT Image 2.5, Slack agent alerting, parallel tool calls, `gpt-6-astra`, service account API key concurrency limits, Music zero retention, conversation filters and MCP tool approval statuses. #### Python SDK - [v2.69.0](https://github.com/elevenlabs/elevenlabs-python/releases/tag/v2.69.0) - Added `transcript_edit` to the realtime Speech to Text wrapper, with edited text delivered through `edited_transcript` events. Fixed Speech Engine JWT verification for API keys with data residency suffixes, and made `play` raise an error when `ffplay` fails. Added `phone_numbers.list_v2` and Flows template methods to list and get templates and list, create and get runs. Regenerated clients and types for GPT Image 2.5, Slack agent alerting, parallel tool calls, `gpt-6-astra`, service account API key concurrency limits, Music zero retention, conversation filters and MCP tool approval statuses. #### ElevenLabs CLI - [v1.3.2](https://github.com/elevenlabs/cli/releases/tag/v1.3.2) - Added optional `--intent` metadata to collect feedback on CLI usage. Added `elevenlabs feedback missing-capability` to report workflows that the CLI does not support. ### API ## New endpoints ### ElevenAgents - [List phone numbers page](/docs/api-reference/phone-numbers/list-v-2) - `GET /v1/convai/v2/phone-numbers` - Added optional `page_size` (integer, 1–1,000, default `100`) and `cursor` (nullable string) pagination parameters. - Added optional `search`, `label`, `phone_number`, `provider`, `supports_outbound`, `agent_id`, `branch_id`, `sort_by` and `sort_direction` filters. `sort_by` accepts `label` or `phone_number`; `sort_direction` defaults to `asc`. - The response contains required `phone_numbers` (array), optional nullable `next_cursor` (string) and `has_more` (boolean, default `false`). ## Updated endpoints ### ElevenAgents - [Create agent](/docs/api-reference/agents/create), [Get agent](/docs/api-reference/agents/get) and [Update agent](/docs/api-reference/agents/update) - Prompt configuration adds `enable_parallel_tool_calls` (boolean, default `true`). Workflow overrides accept a nullable boolean. - The `LLM` enum adds `gpt-6-astra`, including conversation initiation overrides. - Alerting integration notifiers now use `integration_type` to select `pagerduty` or `slack`. Slack notifiers require `connection_id` and `channel_id` (strings); `channel_id` accepts 1–64 characters. - [List conversations](/docs/api-reference/conversations/list) and [Resolve conversation reference](/docs/api-reference/conversations/resolve) - `data_collection_params` no longer accepts the `missing` operator. Use an empty value to match conversations where the field was not collected. - An empty value in `dynamic_variable_params` matches conversations where the variable was not set. - [Create Speech Engine](/docs/api-reference/speech-engine/create), [Get Speech Engine](/docs/api-reference/speech-engine/get) and [Update Speech Engine](/docs/api-reference/speech-engine/update) - Added `cascade_timeout_seconds` (number, 2–15). Create requests default to `4`, update requests accept a nullable value and responses require the field. ### Image and video - [Create image generation](/docs/api-reference/flows/image/create) - `POST /v1/flows/image` - Added request variants for `gpt-image-2.5-flare` and `gpt-image-2.5-sunburst`. - Both variants require `prompt` and `model_id`, accept up to 10 `images`, and add `resolution` (`1K`, `2K` or `4K`, default `1K`). - `quality` accepts `low`, `medium`, `high`, `xhigh` or `max` and defaults to `high`. `aspect_ratio` accepts `auto` and 14 fixed ratios and defaults to `16:9`. ### Dubbing - [Create dubbing project](/docs/api-reference/dubbing/create-project) - `POST /v1/dubbing/project` - Multipart `keyterms` accepts repeated fields or a single JSON array. - Multipart `webhook_ids` accepts repeated fields, a single JSON array or a comma-separated string. - [Get workspace resource](/docs/api-reference/workspace/resources/get), [Share workspace resource](/docs/api-reference/workspace/resources/share) and [Unshare workspace resource](/docs/api-reference/workspace/resources/unshare) - `WorkspaceResourceType` adds `dubbing_project`. ### Knowledge base - [Create crawl job](/docs/api-reference/knowledge-base/create-crawl-job) - `POST /v1/convai/knowledge-base/crawl` - Deprecated `max_depth` (integer, default `3`). The field is now a no-op and no longer has minimum or maximum constraints. - Crawl job metadata no longer requires `max_depth`. ### User - [Get user](/docs/api-reference/user/get) and [Get subscription](/docs/api-reference/user/subscription/get) - Currency enums add `gbp`. ## Schema changes ### Text to Speech - Multi-context WebSocket `audio` and `final` messages now define `is_final_audio_for_turn` as occurring after all buffered bytes for the turn have been delivered.
