GPT-5.2
VerifiedOpenAI's multimodal model for large-scale file, image, and text tasks.
About GPT-5.2
GPT-5.2 combines text, image, and file processing in a single system developed by OpenAI. Its 400,000-token context window allows handling of extended documents and conversations. The model remains proprietary with parameters not publicly disclosed.
It supports complex workflows that involve analyzing mixed media inputs simultaneously. This design enables coherent responses across different data types without requiring separate specialized tools. Users benefit from its unified architecture for tasks that span multiple modalities.
Typical applications include document analysis, visual question answering, and content generation from combined sources. Developers integrate it into platforms needing reliable multimodal capabilities. Its closed nature means access occurs through official OpenAI channels.

Best for
Long Document Reasoning
GPT-5.2 processes and reasons across its full 400,000-token context, enabling coherent analysis of entire books, codebases, or multi-chapter reports in a single session.
Multimodal Report Generation
It combines image understanding with file content analysis to produce integrated text outputs from mixed inputs such as charts, diagrams, and accompanying documents.
Cross-Modal Data Integration
The model links visual elements to textual data for tasks like extracting insights from image-embedded PDFs or generating summaries that reference both modalities.

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-5.2",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: openai/gpt-5.2
