GPT-4o Search Preview
OpenAI · 2025-03-11
GPT-4o Search Preview is OpenAI's fine-tuned, non-reasoning web-search model for Chat Completions; it is a generative model artifact that always searches before responding, not the optional `web_search` or legacy `web_search_preview` tool used with other models in the Responses API. The stable Atlas slug preserves OpenAI's alias, which maps to the sole documented snapshot `gpt-4o-search-preview-2025-03-11`; OpenAI deprecated the preview search model and shut it down on July 23, 2026.
