GPT-4o Search Preview
GPT-4o Search Preview brings real-time web grounding to the GPT-4o multimodal model, allowing it to retrieve current information before generating a response. Unlike the static knowledge cutoff of standard GPT-4o, this variant queries the web at inference time, then synthesizes retrieved content into a coherent, cited answer.
OpenAI targets it at applications where recency is critical — news summaries, stock and market data, live event results, or any domain where the model's training data would be stale. Responses include citations linking back to source pages, enabling users to verify claims. It is currently a preview, meaning behavior and retrieval quality are subject to ongoing refinement.
