About Sonar Pro
Sonar Pro combines large-scale language processing with multimodal capabilities. Its 200k token context enables handling of lengthy documents alongside visual data. Perplexity designed it as a proprietary system rather than an open-weight release.
Strengths center on accurate, search-augmented responses for complex queries. The model integrates current web information with image understanding to reduce hallucinations. Users benefit from its focus on factual depth over creative generation.
Typical usage includes research assistance, image-based analysis, and multi-turn conversations. Professionals rely on it for summarizing reports, verifying facts, and exploring topics that mix textual and visual sources.

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