Problem Description

Right now it can handle only basic tool calls that seem to be executed perhaps on side by some other LLM / tool and then just presents the results back to the model.

Desired Solution you'd like

I would like to see approach more similar to "thinking" process of ChatGPT - where the model is able to recursively run multiple tools (like web search), evaluate results, open more links as needed, and recursively run more tools, thinks and evaluates before presenting user with comprehensive and factually correct verified output.

Basically make it so that model can execute some tool, evaluate its outputs and decide if it wants to run another tool or if it's already ready to get back to the user, right now it's always at best single tool call.

It does in Native Function Calling Mode (model manage the calls to tools), most of the actual models manage its (smaller ones it it have it also is problematic) in Default Mode it doesn't (multitool calls), I made a PR (#17898 ) that do it, sequential tool calls in default mode.
An alternative approach until a more robust one is officialy deployed.

oh wow that simple stupid toggle to enable "native" tool usage is a MASSIVE improvement (I use gpt-oss:20b), such a simple toggle, so easily overlooked and it turns Open WebUI into ENTIRELY different thing that is uncomparably better.

Why is this feature not more visible? Right now that toggle is so much buried somewhere inside that panel with many other toggles, it should be one of primary preferences options. Out of all possible config options I have tried, this one has definitely biggest impact on quality of Open WebUI.

@benapetr sounds like you've seen lots of difference. would you mind share a bit more what tools you managed to intergreate with the models?
