LLMLib

LLMLib is a simple Python library for making requests to Language Learning Models (LLMs) such as OpenAI's GPT and Anthropic's Claude.

Installation

You can install LLMLib using pip:

pip install llmlib-amq

Usage

Here's a quick example of how to use LLMLib:

from PIL import Image
from pathlib import Path
from llmlib import LLMClient, Provider, AnthropicModel, OpenAIModel, Role, \
    LLMResponse, TextMessage, ImageMessage, print_stream, encode_image_webp
import os


client = LLMClient(
    provider=Provider.ANTHROPIC,
    model=AnthropicModel.CLAUDE_3_5_SONNET_20241022,
    # provider=Provider.OPENAI,
    # model=OpenAIModel.GPT_4O,
    openai_key=os.environ["OPENAI_API_KEY"],
    anthropic_key=os.environ["ANTHROPIC_API_KEY"],
)
