Show HN: Abso – TypeScript LLM Client

Hi HN,

I made a TypeScript library that unifies queries with different LLM providers like Anthropic and Gemini into the OpenAI format.

When playing around with new models like the new Gemini 2.0, it's frustrating to adapt to the differences in things like streaming, tool calling, json formatting, output formats, etc.

This library aims to make it easy to switch between providers, while keeping the OpenAI format, which seems to have become the de-facto standard. Maybe this can be helpful to others.
