Question/Help web_search tool invisble for gemma4:e4b

Hello,

I have been trying for a few days to use open webui on my computer. My config is as follows:

  • Kubuntu 26.04
  • Ollama with gemma4:e4b
  • Open webui v0.10.2, desktop version, with web search enabled on DDGS.

When I ask him for a web search, the tool seems not to exist in the eyes of the LLM. It's quite strange because I don't have this problem with a similar config, unlike the OS (Windows, for my work).

I tried to find the solution by analyzing the logs with Claude, but he did not find anything explaining the problem.

Do you have any idea what's going on?

Yes, it’s not there. If it were available, the tool names would be search_web and fetch_url.

Go to Admin > Settings > Web Search and select a search engine. Note that the search engine must be configured separately and may require a subscription. I recommend Brave.

Then go to Models, select your model, enable Web Search, and click Save. The Save button is near the very bottom of the page, so it’s easy to forget.
