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 and JavaScript

   The library is primarily designed for use with TypeScript and JavaScript, which can be a limitation for developers working in other languages.

2. 02

   Dependence on third-party LLM APIs can lead to vendor lock-in

   Integration heavily relies on specific hosted API providers, making it difficult to switch or diversify LLM services without significant changes.

3. 03

   Poor documentation for advanced use cases and troubleshooting

   The official documentation lacks detailed examples and explanations for complex scenarios, leading to a steep learning curve for new users.

4. 04

   Performance issues with large-scale deployments

   Users have reported increased latency and resource consumption when scaling the application beyond a certain number of concurrent requests.

What it does well

• OpenAI-compatible API for calling any hosted LLMs.

• Supports TypeScript and JavaScript.
