This information is very useful to the open source community. Whats the rationale in not "building in the public"? Is Ollama turning its back on the open source community? Also why should we believe ollama web search is better than my locally run searxng server?

Oh yes! that is why I want to provide the names of the providers we use. I do believe in building in the open. The web search functionality has a very generous free tier (it is behind Ollama's free account to prevent abuse) that allows you to give it a try comparing to running a searxng server locally.

On making the search functionality locally -- we made considerations and gave it a try but had trouble around result quality and websites blocking Ollama for making a crawler. Using a hosted API, we can get results for users much faster. I'd want us to revisit this at some point. I believe in having the power of local.
