This is a fork of github/mostlygeek/llama-swap for the project github/LM4eu/goinfer.

Back in 2023, Goinfer was an early local LLM proxy swapping models and supporting Ollama, Llamacpp, and KoboldCpp. To simplify the maintenance, we decided in August 2025 to replace our process management with another well-maintained project.

As we do not use Ollama / KoboldCpp any more, we integrated llama-swap into Goinfer to handle communication with llama-server.

1. The command go get github.com/mostlygeek/llama-swap@v123 fails because the version numbering v123 does not conform the Go standard v1.2.3. The workaround is to use go get github.com/mostlygeek/llama-swap@main that sets v0.0.0-20250925224418-bab7d1f3968a in go.mod.

2. Importing llama-swap using this workaround is not enough because the compilation requires the folder proxy/ui_dist that does not exist within the source code.

   //go:embed ui_dist
   var reactStaticFS embed.FS

   The second workaround is to clone llama-swap and use a go.work file.

3. At LM4eu, we want to use the web UI of the underlying inference engine (e.g. llama.cpp). But the current llama-swap always require the model name within the client request (JSON). This is not possible to access a web page.

1. Use version v0.0.123 compatible with Go expectations.
2. Add a minimalist proxy/ui_dist/index.html.
3. When no model is specified in the request, llama-swap defaults to the running model (first found).

We will adapt to the upstream project evolutions, while minimizing our patches.

But we may need to add more patches that may pollute the upstream project.

So we prefer to see if the project github/LM4eu/goinfer is successful. In that case we will discuss how to integrate our changes into the upstream project.

Special thanks to Benson Wong for maintaining llama-swap with clean and well-documented code.

Compared to some alternatives, we enjoy the readable source code of llama-swap. We also appreciate its author, Benson Wong, regularly improves the code.
