Expose a public method for retrieving all stored memories outside the
pipeline, avoiding the need for callers to reimplement client branching,
OR filter construction, and asyncio.to_thread wrapping. Simplify the
example get_initial_greeting() to use it.
Move blocking Mem0 API calls off the event loop using asyncio.to_thread().
Store messages as a fire-and-forget background task via create_task() since
the result is not needed. Insert memory messages at the configured position
in the context instead of always appending.
Closes#1741
When an InterruptionFrame arrives, the Python-side audio task is
cancelled but frames already submitted to rtc.AudioSource continue
playing from its internal buffer. This causes the bot to keep speaking
for several seconds after being interrupted.
Fix by overriding process_frame in LiveKitOutputTransport to call
audio_source.clear_queue() on InterruptionFrame, immediately flushing
the buffered audio.
Set GRPC_VERBOSITY=ERROR by default so users do not see noisy fork
handler and abseil warnings from the gRPC C library. Users can still
override by setting GRPC_VERBOSITY themselves.
nvidia-riva-client 2.25.1 ships with gencode compiled against protobuf
6.31.1, which requires a runtime >= 6.31.1. Update protobuf from 5.29.6
to >=6.31.1,<7 and grpcio-tools from 1.67.1 to 1.78.0 to match.
Regenerate frames_pb2.py with the new compiler.
Both GrokLLMService and XAIHttpTTSService use the same xAI API (api.x.ai),
so move Grok source files into the xai module. Leave deprecation shims in
the old grok/ paths for backward compatibility.
- Rename XAITTSService → XAIHttpTTSService and XAITTSSettings → XAIHttpTTSSettings
- Add language_to_xai_language() with explicit LANGUAGE_MAP using resolve_language()
- Remove deprecated InputParams, params, voice, language init params
- Remove XAI_DEFAULT_SAMPLE_RATE and XAI_PCM_CODEC constants; add encoding param
- Set sample_rate=None default (picked up from PipelineParams or user)
- Use Language.EN enum instead of string "en" for default language
- Add changelog/4031.added.md
- Add 07e-interruptible-xai.py foundational example
- Update 14g-function-calling-grok.py to use XAIHttpTTSService
- Register 07e in run-release-evals.py
Test that OpenAI Realtime, Grok Realtime, and Nova Sonic adapters
prefer init-provided system_instruction over context-provided, warn
on conflicts, and don't warn for developer messages.
Add system_instruction parameter to the Grok Realtime adapter's
get_llm_invocation_params() and call _resolve_system_instruction() to
prefer init-provided over context-provided system instructions and
warn on conflicts. Previously context-provided took precedence.
Update the Grok Realtime example to use settings.system_instruction
instead of session_properties.instructions.
Add system_instruction parameter to the OpenAI Realtime adapter's
get_llm_invocation_params() and call _resolve_system_instruction() to
prefer init-provided over context-provided system instructions and
warn on conflicts. Previously context-provided took precedence.
Add system_instruction parameter to the Nova Sonic adapter's
get_llm_invocation_params() and call _resolve_system_instruction() to
prefer init-provided over context-provided system instructions and
warn on conflicts. Previously context-provided took precedence.
Remove the service-side fallback logic, as the adapter now handles
resolution.
Pass self._system_instruction_from_init to the adapter's
get_llm_invocation_params(), which calls _resolve_system_instruction()
to prefer init-provided over context-provided system instructions and
warn on conflicts. Previously context-provided took precedence.
Also fix the reconnect check to only reconnect when the resolved
system instruction actually differs from what the initial connection
used, avoiding unnecessary reconnects.
The previous default (meta-llama/Meta-Llama-3.1-8B-Instruct-Turbo) is
no longer available as a serverless Together.ai model and now requires a
custom deployment. The new default is openai/gpt-oss-20b, one of
Together's recommended models for small & fast use-cases.
OpenAI-compatible services that don't support the "developer" message
role can now set supports_developer_role = False on the service class.
BaseOpenAILLMService passes this as convert_developer_to_user to the
adapter, which converts developer messages to user messages before
sending them to the API. Applied to Cerebras and Perplexity.
Also removes the now-redundant developer→user conversion step from
PerplexityLLMAdapter (handled by the parent adapter via the flag).
_system_instruction_from_init was being set from the deprecated
`system_instruction` constructor parameter instead of
`self._settings.system_instruction`, so system instructions provided
via settings were silently ignored.
OpenAI Realtime, Grok Realtime, and AWS Nova Sonic adapters now convert
"developer" role messages to "user" (consistent with all other non-OpenAI
adapters). Previously these messages were silently dropped. Adds starter
unit tests for all three realtime adapters.
These messages are developer instructions to the assistant (e.g. "Please
introduce yourself to the user"), not simulated user input. The
"developer" role is semantically correct for this purpose.
