That's what i have together with open webui and gpt-oss-120b. it works reasonably well. But sometimes the searches are slow.
You can try removing search engines that fail or reducing their timeout setting to something faster than the default of a few seconds.
SearXNG is fast, its mostly the code that triggers the searches. Because, my daily is chatgpt, i still did not try to tweak it.
I haven't needed to tweak mine for similar reasons, but I'm surprised to hear that the "code that triggers the searches" is slow. Are you referring to something in Open WebUI?
I haven't tried SearXNG personally. How does it compare to Ollama's web search in terms of the search content returned?
I have no idea how well Ollama's works, but I haven't ran into any issues with SearXNG. The alternatives aren't worth paying for in any use case I've encountered.
