pipecat-ai/pipecat v1.10.0

on GitHub

Added

• SmallestTTSService now uses Smallest AI's continuation API: text fragments within the same LLM turn share a context_id so the server joins them into one continuous generation instead of resetting prosody on each request. Added an optional max_buffer_delay_ms setting to control the server-side buffering window.
  (PR #5626)

• Added LiveKitParams.audio_out_queue_size_ms to configure the outgoing rtc.AudioSource buffer size. Defaults to LiveKit's 1000 ms, so existing behaviour is unchanged.
  (PR #5699)

• Added enable_turn_detection to GradiumSTTService. With it on, Gradium's server-side end-pointing signal decides when user turns start and end instead of the pipeline's VAD, and the service recommends ExternalUserTurnStrategies to the user aggregator. The new eot_horizon_s, eot_threshold and post_flush_cooldown_frames settings tune it.
  (PR #5706)

Changed

• ⚠️ Behavior change: Pipecat now supports the openai 3 SDK, and the openai dependency is widened to >=1.74.0,<4, so a fresh resolve picks openai 3. It builds its HTTP clients on httpx2 instead of httpx, and TLS certificates then verify against the operating system trust store rather than certifi. Minimal container images without system CA certificates, and environments behind a TLS-inspecting proxy, may need SSL_CERT_FILE or SSL_CERT_DIR pointed at a CA bundle. Pin openai<3 to stay on the previous HTTP stack.

  A `Timeout` passed to a service's `http_client` — `OpenAITTSService` and
  

  the Whisper-based STT services — must come from the HTTP client family the
  installed SDK uses: httpx2 on openai 3, httpx before it.
  (PR #5620)

• Widened the anthropic dependency to >=0.49.0,<2 to support the anthropic 1 SDK. AnthropicLLMService sends temperature, top_k and top_p through the request's extra_body, since the Messages API methods dropped them as parameters in anthropic 1. Requests reach the API unchanged, and the settings keep their names and meaning.

  If you pass your own Bedrock client, anthropic 1 requires an explicit
  

  region — AsyncAnthropicBedrock(aws_region=...), or AWS_REGION in the
  environment — where it previously fell back to us-east-1.
  (PR #5623)

• Widened the mcp dependency to mcp[cli]>=1.24.0,<3 so MCPClient works with the MCP SDK's 2.x line as well as 1.x. The floor moves to 1.24.0, the first release carrying the streamable_http_client transport that both lines share.
  (PR #5624)

• SpeechmaticsSTTService reconnects with exponential backoff after a dropped connection or a recoverable server error, buffering audio meanwhile. A rejected credential, rejected session, request-rejecting server error, or exhausted reconnect attempts are reported as a permanent error, leaving the service unusable for the PipelineWorker's ProcessorUnusablePolicy to act on. A settings update that requires a reconnect gives a rejected session another chance.
  (PR #5631)

• ⚠️ Breaking change: SpeechmaticsSTTService now targets Speechmatics Agent STT (/v2/agent) through the speechmatics-agent-stt SDK, which replaces speechmatics-voice[smart] in the speechmatics extra. The service cannot connect to the legacy real-time endpoint. The default turn_detection_mode is now TurnDetectionMode.VAD, so Speechmatics closes turns server-side and the service recommends ExternalUserTurnStrategies; pass turn_detection_mode=TurnDetectionMode.EXTERNAL to keep driving turns from Pipecat's own VAD. The default model is linden-1, selected by the new model setting. Settings.include_partials is renamed enable_partials.
  (PR #5631)

• The pipecat eval suite live dashboard now shows a repeated (bot, scenario) row's pass rate while its attempts are still running, beside how many are left, instead of only once every attempt is in. A pass rate, on the dashboard and in the piped summary, is green while every finished attempt passed and red once one has failed; the yellow middle band is gone.
  (PR #5704)

• The recording line in pipecat eval suite's settings now says which of the selected runs will actually record. Only an audio-mode run produces audio, so with recording on it reads on (3 of 6 runs; text mode skipped) when the selection is mixed and off (all runs text mode) when nothing will be recorded. pipecat eval run -a prints the same line.
  (PR #5707)

• DeepSeekLLMService now defaults thinking to disabled. DeepSeek's V4 models otherwise reason before every answer, which delays the first spoken token. Pass thinking=DeepSeekLLMService.ThinkingConfig(type="enabled") to turn it on, or thinking=None to use DeepSeek's own default.
  (PR #5710)

Deprecated

• Deprecated SpeechmaticsSTTService operating_point on Settings and InputParams; use model instead. Passing it still selects the model and emits a DeprecationWarning. It will be removed in 2.0.0.
  (PR #5631)

Removed

• ⚠️ Breaking change: Agent STT has no speaker focus, so SpeechmaticsSTTService no longer exports SpeakerFocusMode or SpeakerFocusConfig, and UpdateParams and update_params() are removed. The Settings and InputParams fields focus_speakers, ignore_speakers, focus_mode, speaker_passive_format, max_delay, end_of_utterance_silence_trigger, end_of_utterance_max_delay, split_sentences, include_results, and extra_params are removed, as are TurnDetectionMode.FIXED, ADAPTIVE, and SMART_TURN. OperatingPoint is replaced by Model.
  (PR #5631)

• ⚠️ Removed LmntTTSService. LMNT has shut down and is no longer available.
  (PR #5698)

Fixed

• Fixed the WebSocket transports treating an audio frame as unsent whenever the serializer emitted no payload for it. A serializer that resamples through a stream resampler buffers audio across calls and emits it in a later one, so on a pipeline whose output sample rate differs from the wire rate most frames took that path. Those frames are now paced and pushed downstream like any other, so the output queue drains at playback speed again and BotStoppedSpeakingFrame and the EndFrame behind it are no longer reached early, which matters most where the serializer hangs up the call on the EndFrame.
  (PR #5593)

• Fixed PIPECAT_SETUP_FILES parsing on platforms whose path separator is not a colon.
  (PR #5638)

• Fixed the pipecat eval suite live dashboard showing a repeated (bot, scenario) row as idle while a finished attempt's bot was still being stopped. The row now keeps spinning until its concurrency slot is released. EvalRun gains a stopping flag for that window.
  (PR #5704)

• Async function calls (cancel_on_interruption=False) whose result arrives before the conversation moves on are now recorded as ordinary tool results, without the deferred-result message that asks the LLM to convey them. The deferred delivery still applies when the LLM has responded, a new message has landed, or the call sent an intermediate update in the meantime.
  (PR #5705)

• Fixed DeepSeekLLMService failing every request after a tool call in thinking mode with a 400 (The reasoning_content in the thinking mode must be passed back to the API). DeepSeek requires reasoning_content on each assistant message of the current turn once a tool call is involved; the new DeepSeekLLMAdapter supplies an empty one on assistant messages that have none.
