Re: gpt-oss tool calls support, I don't think that's true, I've been using it for days. Then again, I did write my own harmony parser...(Noting for audience as you imply, neither does Ollama. Thing here is you either gotta hope all your users have nicely formed templates in their ggufs (they do not) or sometimes step in to ex. here, note the OpenAI chat completions-alike API llama.cpp provides will output a text response that you'll need to parse into a tool call yourself, until they implement a harmony parser)
