Feature Request: Integrate Models' Native Web Search

The Gemini API has a new feature where you can ground results with Google search which reduces hallucinations and provides references to content.

https://developers.googleblog.com/en/gemini-api-and-ai-studio-now-offer-grounding-with-google-search/

Here's the important description of the feature "the model returns grounding sources (in-line supporting links) and Search Suggestions that point users to the search results corresponding to the grounded response."

Would be great to have a button similar to the “Thinking Mode” to toggle the use of server-side web search tools already available for all major LLM providers. See:

openai: https://platform.openai.com/docs/guides/tools-web-search?api-mode=responses

gemini: https://ai.google.dev/gemini-api/docs/google-search

anthropic: https://platform.claude.com/docs/en/agents-and-tools/tool-use/web-search-tool

Right now to use this feature we have to duplicate each model and add a custom body parameter. It’s much cleaner to toggle web search on demand than have every model duplicated.

Moreover, there are other providers which also offer server-side web search: xAI, Open Router, Groq and probably many others. Given how common web search has become, we could even have a couple of special input fields when adding a custom model to fill the name and value of the web search tool, and in that way be able to use the same toggle button.
