A Unified Interface for Diverse LLMs

MODIHUB: A Unified Interface for Diverse LLMs

MODIHUB simplifies the way you interact with multiple Large Language Models (LLMs) by offering a streamlined, consistent interface. It abstracts the complexities of provider-specific APIs and configurations, making it easy to switch between models across different platforms.

🔑 Key Features

• Unified API: Seamlessly interact with models from OpenAI, Gemini, Anthropic, Ollama, Groq, and more using a consistent interface.
• Model Discovery: Effortlessly list and explore available models from each provider.
• Multimodal Support: Work with text, image, and mixed-modality prompts where supported.
• Built-in Evaluation Tools: Evaluate model performance with utilities for perplexity, lexical diversity, and more.

Installation

pip install -U modihub

Usage Examples

1. Listing Available Models

from modihub.llm import LLM

available_models = LLM.available_models()
for client, models in available_models.group_by("client"):
    print(f"{client}:")
    for model in models:
        print(f"  - {model.name}")

2. Text Generation

from modihub.llm import LLM
from dotenv import find_dotenv, load_dotenv

load_dotenv(find_dotenv()) # Loads API keys from .env file

# Replace with your desired model
llm = LLM.create("gpt-4o-mini")
# Generate text
response = llm("Tell me a joke about AI.")
print(response)

3. Multimodal Input (Image Description)

from PIL import Image
from modihub.llm import LLM
from dotenv import find_dotenv, load_dotenv

load_dotenv(find_dotenv())
# Replace with your desired model
llm = LLM.create("models/gemini-1.5-flash-8b")
# Load image
image = Image.open("image.png")  # Replace with the path to your image
text = "Describe the following image"
# create multimodal prompt
prompt = [text, image]
response = llm(prompt)
print(response)

4. Model Evaluation (Pointwise Metrics)

from dotenv import find_dotenv, load_dotenv
from modihub.metrics import Perplexity, LexicalDiversity
from modihub.eval import Evaluator

load_dotenv(find_dotenv())

prompts = [
    "What are LLMs?",
    "Explain AI", "What is the meaning of life?"]
models = [
    "gpt-4o-mini",
    "llama3.1:latest",
    "models/gemini-1.5-flash-latest"
]
metrics = [Perplexity(), LexicalDiversity()]

evaluator = Evaluator(models, metrics)
results = {prompt: evaluator.evaluate(prompt) for prompt in prompts}
for prompt, result in results.items():
    print(f"Prompt: {prompt}")
    for model, metrics in zip(models, result):
        print(f"{model}: {metrics}")
    print()

Configuration

• API Keys: Set your API keys for each LLM provider as environment variables (e.g., OPENAI_API_KEY, GEMINI_API_KEY, ANTHROPIC_API_KEY, or GROQ_API_KEY). A .env file in your project directory is a good place to store these.
• Support Clients: MODI currently supports OpenAI, Gemini, Anthropic, Ollama, and Groq models. You can add support for additional clients by implementing the LLMClient interface.
• System Instructions: Use the system_instruction parameter when creating an LLM instance to provide context or instructions to the model. This is supported by all clients.
