This comparison examines the search capabilities and filtering options available across major AI language model search APIs.
Comparison[edit]
OpenAI Web search - OpenAI API
- Filter domains: ✅ Available
- Filter date: Not supported
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."
Claude AI Search Web search tool - Anthropic
- Filter domains: ✅ Available
- Filter date: Not supported 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
Gemini + Enable Grounding with Google Search
- Filter domains: Not supported
- Filter date: Not supported
- Localize search results:
Gemini + Enable URL context feature
- Filter domains: ✅ Available. Can analyze up to 20 URLs per request as defined in prompt content[1]
- Filter date: Not supported
- Localize search results:
- Comment: I tested AIStudio by restricting company news searches to 20 specified news websites. Despite this constraint, the results still included content from unrelated domains.
Perplexity Sonar [Last visited: 2026-01-21]
- Filter domains: ✅ Available. Supports maximum of 10 domains[2]
- Filter date: ✅ Available[3] While a time range can be specified via parameters (last_updated_after_filter, after_date, search_recency_filter), testing on sonar-pro model showed significant inconsistencies—publication dates of results frequently fell outside the specified range.
- Localize search results: ✅ Available[4]
- Filter domains: ✅ Available with three parameters
- Parameter: allowed_websites
- Parameter: excluded_websites
- Parameter: sources. You also can customize data sources including web, X search, news, and RSS feeds.
- Filter date: ✅ Available with from_date and to_date parameters. Testing on grok-4-1-fast showed minor inconsistencies—1 out of 4 news results had a date outside the specified range.
- Localize search results: ✅ Available with country parameter.
