I’ve been building GoModel since December with a couple of contributors. It's an open-source AI gateway that sits between your app and model providers like OpenAI, Anthropic or others.

I built it for my startup to solve a few problems:

  - track AI usage and cost per client or team
  - switch models without changing app code
  - debug request flows more easily
  - reduce AI spendings with exact and semantic caching

  - ~17MB docker image
    - LiteLLM's image is more than 44x bigger ("docker.litellm.ai/berriai/litellm:latest" ~ 746 MB on amd64)
  - request workflow is visible and easy to inspect    
  - config is environment-variable-first by default

Any feedback is appreciated.
