What it is

Abso is a TypeScript SDK that simplifies the process of integrating and calling over 100 large language models (LLMs) by standardizing them to use OpenAI’s API format. This makes it easier for developers to experiment with different models without changing their codebase.

Lunary AI Abso stands out by providing a standardized TypeScript SDK that simplifies the integration and experimentation with over 100 large language models, making it easier for developers to leverage different models without changing their codebase.

When it fits — and when it doesn’t

A good fit for

  • TypeScript developers who need to quickly test and integrate multiple LLMs in their applications

  • Teams working on projects that require flexibility in choosing the best-performing language models

  • Researchers looking for a standardized way to experiment with different large language models

Look elsewhere if

  • Projects requiring real-time streaming capabilities (Abso is designed for batch processing)

  • Developers who prefer using native APIs of each LLM rather than a unified format

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Steep learning curve for non-TypeScript developers

    The SDK is primarily in TypeScript, which may require additional time and effort to learn for developers unfamiliar with the language.

  2. 02

    Limited documentation and examples

    The project's documentation lacks comprehensive guides and practical examples, making it harder for new users to understand how to integrate different LLMs effectively.

  3. 03

    Frequent breaking changes between versions

    Users have reported significant changes in API structure from v0.1 to v0.2, requiring substantial code updates and rework for existing projects.

  4. 04

    Dependence on third-party models' availability and stability

    Integration with over 100 LLMs means that the reliability of Abso is partially dependent on the uptime and performance of these external services, which can vary.

  5. 05

    Complex setup for certain models

    Setting up some less popular or specialized LLMs through Abso can be more complex due to limited support and community resources compared to widely used models like OpenAI's.

What it does well

  • Standardizes over 100 LLMs to use OpenAI's API format

  • Simplifies integration and experimentation with different models

  • Open-source under MIT license
