VoiceRun Completions

voicerun_completions

A comprehensive, unified SDK for interacting with multiple LLM providers (OpenAI, Anthropic, Google, and Vertex Anthropic) through a single, consistent API. This library simplifies working with different providers by normalizing their APIs and providing powerful features like automatic fallbacks, retry logic, and advanced streaming options.

Quick Start

from primfunctions.events import Event, StartEvent, TextEvent, TextToSpeechEvent
from primfunctions.context import Context
from voicerun_completions import generate_chat_completion

async def handler(event: Event, context: Context):
    if isinstance(event, StartEvent):
        yield TextToSpeechEvent(
            text="Hello! Ask me anything and I'll answer your question.",
            voice="nova"
        )

    if isinstance(event, TextEvent):
        user_message = event.data.get("text", "")
        
        response = await generate_chat_completion({
            "provider": "openai",
            "api_key": context.variables.get("OPENAI_API_KEY"),
            "model": "gpt-5-mini",
            "messages": [
                {"role": "user", "content": user_message}
            ]
        })
        
        if response.message.content:
            yield TextToSpeechEvent(
                text=response.message.content,
                voice="nova"
            )

Testing

Install dev dependencies:

uv pip install -e ".[dev]"

Run unit tests (no API keys required):

uv run pytest -m "not integration" -v

Run all tests including integration (requires API keys in environment):

uv run pytest -v

Run a specific test file:

uv run pytest tests/test_google_schema_sanitization.py -v

Integration tests require one or more of these environment variables:

• OPENAI_API_KEY
• ANTHROPIC_API_KEY
• GEMINI_API_KEY
• GCP_SERVICE_ACCOUNT_JSON / GCP_PROJECT_ID (for Vertex tests)

Tests missing the required key will be skipped automatically.

Features

• Unified API - Single interface for OpenAI, Anthropic, Google, and Vertex Anthropic
• Automatic Fallbacks - Seamlessly fallback to alternative providers on failure
• Retry Logic - Built-in exponential backoff retry mechanism
• Advanced Streaming - Token-based and sentence-based streaming for real-time applications
• Tool Calling - Unified tool/function calling across all providers
• Type Safety - Full type hints and support for both dict and object formats
