== Comparison ==
{{Gd}} OpenAI [https://platform.openai.com/docs/guides/tools-web-search?api-mode=responses Web search - OpenAI API]
* Filter domains: ✅ Available
* Filter date: Not supported {{exclaim}} However, prompt-based date filtering works effectively. Testing with GPT-5.1, GPT-5.2 and GPT-5.4 successfully returned news results matching the specified date criteria.
* Localize search results: ✅ Available "To refine search results based on geography, you can specify an approximate user location using country, city, region, and/or timezone."

* Filter domains: ✅ Available
* Filter date: Not supported {{exclaim}} Date filtering is not available as an API parameter. Attempting to filter by date through prompting (tested on claude-sonnet-4-5-20250929 and claude-sonnet-4.6) was unreliable, often yielding no results or out-of-range articles.
* Localize search results: ✅ Available
