ai-infra 0.1.112

Infrastructure for efficient and scalable AI applications.

ai-infra

Production-ready Python SDK for building AI applications with LLMs, agents, and multimodal capabilities.

ai-infra provides clean interfaces for chat, agents, embeddings, voice, and image generation across 10+ providers—all with zero-config defaults.

✨ Features

• LLM: Chat, structured output, streaming, retries, multi-turn conversations
• Agents: Tool calling, human-in-the-loop, provider fallbacks, autonomous deep mode
• Graph: LangGraph workflows with typed state and conditional branching
• Embeddings & RAG: Vector storage, document retrieval, multiple backends
• Multimodal: Text-to-speech, speech-to-text, vision, realtime voice
• Image Generation: DALL-E, Imagen, Stability AI, Replicate
• MCP: Model Context Protocol client/server, OpenAPI→MCP conversion

🚀 Quick Start

5 lines to your first chat:

from ai_infra import LLM

llm = LLM()  # Auto-detects configured provider
response = llm.chat("What is the capital of France?")
print(response)

With tools (agent):

from ai_infra import Agent

def get_weather(city: str) -> str:
    """Get weather for a city."""
    return f"Weather in {city}: 72°F, sunny"

agent = Agent(tools=[get_weather])
result = agent.run("What's the weather in Tokyo?")
print(result)

📦 Installation

Python: 3.11 – 3.13

# Using pip
pip install ai-infra

# Using Poetry (development)
poetry install
poetry shell
