## Description

This is a Python SDK for interacting with large language models via API. It serves as a client library to generate text, process messages, and manage conversational states, while providing a specialized interface for connecting to models hosted across different cloud infrastructure providers.

The SDK includes a tool-calling framework that maps Python functions to JSON schemas, allowing models to execute external tools. It also features a built-in token counting utility to estimate input size before transmission and a server-sent events client for receiving model tokens in real time.

The library covers a broad range of capabilities, including asynchronous batch processing for large-scale prompt handling, automated pagination of API results, and file upload management. It also implements traffic management through automatic request retries with exponential backoff to handle transient network errors and rate limits.
