What it is

The @airouter.io/airouter-sdk is an official Typescript SDK that automates routing of API requests to the most suitable LLM. It simplifies integration and optimization for developers working on AI-driven applications.

The @airouter.io/airouter-sdk stands out as a specialized TypeScript SDK for automating the routing of requests to the best LLM, offering unique performance and cost optimization benefits.

When it fits — and when it doesn’t

A good fit for

  • Teams building complex AI applications where optimal model selection is critical for performance and cost-efficiency

  • Developers working with TypeScript who need to integrate multiple LLMs into their projects

Look elsewhere if

  • Projects requiring real-time streaming capabilities (batch-only architecture)

  • Budget-constrained projects that cannot afford usage-based pricing models

Known weaknesses

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

  1. 01

    Limited language support beyond TypeScript

    The SDK is primarily designed for TypeScript, limiting its usability in other languages.

  2. 02

    Vendor lock-in due to proprietary technology

    Switching from @airouter.io/airouter-sdk to another service may require significant refactoring of the application codebase.

  3. 03

    Poor documentation for advanced use cases

    The official documentation lacks detailed examples and explanations for complex scenarios, making it difficult for developers to fully leverage the SDK's capabilities.

  4. 04

    Expensive at scale due to per-request pricing model

    Costs can quickly escalate as usage grows, especially if not carefully managed with rate limiting or other optimization techniques.

What it does well

  • Automated routing to the best LLM for each request

  • Optimized performance and cost-efficiency

  • Simplified integration with existing TypeScript projects
