VerifiedPreview model for enhanced search and information synthesis.
About GPT-4o Search Preview
Built on the GPT-4o architecture, this preview version emphasizes handling of complex queries that require pulling and organizing external information. Its large context window supports processing lengthy documents or multi-turn research sessions without losing coherence. The closed nature allows OpenAI to iterate quickly on search-specific refinements before wider release.
Strengths include reliable text generation combined with preview access to real-time data integration features. Users benefit from more accurate summarization of current events or technical topics compared to standard models. It avoids open-weight distribution to maintain controlled testing of these new capabilities.
Typical usage involves research assistance, fact-checking workflows, and exploratory question answering where up-to-date context matters. Developers and power users test it for applications needing precise information retrieval within extended conversations.

Quick start
OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. Only the model slug changes between models.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://openrouter.ai/api/v1",
apiKey: process.env.OPENROUTER_API_KEY,
});
const completion = await client.chat.completions.create({
model: "openai/gpt-4o-search-preview",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: openai/gpt-4o-search-preview
