"LLM is created so engineer don’t have to write a report", anyway found out ONLYOFFICE can connect to OpenAI compatible, using Qwen 3.6 to do elaboration.

It is pluggin made for ONLYOFFICE, much simpler than copy-paste from webui.

PS. Switch to non thinking/reasoning when using this, and the best model for this is Gemma line up. even E2B is strong enough to do language modelling.

I dont use libre or Microsoft Office so i dont know whether it is supported or not
