Adapters as API gateways to Different LLM Models

Adapters Package Documentation

Overview

The Adapters package facilitates communication between different language model APIs by providing a unified interface for interaction. This ensures ease of use and flexibility in integrating multiple models from various providers.

The package can be installed an used via pip:

pip install martian-adapters

Getting Started

Prerequisites

• Python version: 3.11.6
• Poetry

Installation

poetry install
poetry run pre-commit install

Setting Up Pre-commit

Pre-commit hooks help maintain code quality and standards. Install them with the following command:

poetry run pre-commit install

To run pre-commit manually:

poetry run pre-commit run --all-files

Semantic Versioning

For versioning we follow Semantic Versioning

Environment Configuration

The package requires certain environment variables to be set by the users:

• Copy .env-example to .env and populate it with appropriate values.

Running Tests

Ensure Python 3.11 is used:

poetry run pytest

Quickstart

from adapters import AdapterFactory, Prompt

adapter = AdapterFactory.get_adapter_by_path("openai/openai/gpt-4o-mini")

prompt = Prompt("Who is your favorite Martian?")
conversation = adapter.convert_to_input(prompt)

adapter.execute_sync(conversation)

Adapter paths follows the format provider/vendor/model_name. Use AdapterFactory.get_supported_models() to retrieve all supported models. For a given model, model.get_path() returns the adapter path.

Contributing

Adding New Models

1. Existing Providers: Add new models to the SUPPORTED_MODELS array if the provider is already supported.

2. New Providers:

   • If the provider follows the OpenAI format, model integration is straightforward. See the "Together" provider class as an example.
   • For providers with different schemas, see the "Anthropic" provider class for guidance.

Development Steps

1. Add the Provider and Model: Update provider_adapters/__init__.py and test files accordingly.

2. Write Tests: Add tests in the relevant directories. Use @pytest.mark.vcr for tests making network requests.

3. Run Tests:

   poetry run pytest
   

4. Check-in Cassette Files: Include any new cassette YAML files in your commit.

5. Send a Pull Request: Ensure all tests pass before requesting a review.

Re-creating Cassette Files

Use the --record-mode=rewrite option with pytest to update cassette files.

Additional Notes

Some models may only be accessible from specific locations (e.g., the U.S.). In such cases, running tests might require access to a U.S.-based server.

This documentation provides a streamlined approach to using and contributing to the Adapters package, emphasizing practical steps and clear examples.
