OpenAI has officially launched a new search-focused model based on GPT-5, available through the Chat Completions API under the identifiers gpt-5-search-api and gpt-5-search-api-2025-10-14. The model is now live on the OpenAI platform and can be directly accessed by developers. Priced at $10 per 1,000 API calls, the new model offers a 60% reduction in cost compared to previous search solutions, significantly improving its cost efficiency. It supports domain-specific filtering of search results, allowing users to narrow down outputs to specific websites or domains—just like the web search functionality in the Responses API. This feature enhances precision and control, making the model particularly useful for applications requiring targeted, reliable information retrieval. The launch marks a key step in OpenAI’s effort to strengthen its AI-powered search capabilities, enabling more accurate and context-aware responses by integrating real-time web data with advanced language understanding.
