Sonar Pro example: reading an image into JSON

The example is picked from this model's own capabilities. Drop in your key and it runs as is.

What is Sonar Pro good for?

Sonar Pro is one of Perplexity's models. Put "perplexity/sonar-pro" in the model field and the rest of your code stays as it is. Sonar Pro keeps 200,000 tokens in view at once, and that number is what caps the conversation history in your product. A single response can run to 8,000 tokens. On price it sits in the "expensive" band — cheaper than 31 and dearer than 360 of the other paid models in the catalogue.

What you get on top of text in, text out: it reads images directly, which makes it a real option for invoices, forms and screenshots. All of it works through the standard parameters of the official OpenAI SDK — no custom client, no wrapper.

Input runs at 1,038,658 toman per 1M tokens and output at 5,193,290 — output costs 5× input, so trimming the answer saves more than trimming the prompt. You are always charged for the usage the request actually reported, never for the estimate, and a failed request costs nothing.

The closest alternative with the same capabilities from a different provider is GPT-5.4 Image 2: Sonar Pro works out about 23% cheaper, and its context window is smaller. Both run on the same key and the same code, so trying the other one is a single string change.

To make the figure concrete: 100,000 toman of credit buys roughly 12 thousand-word requests on Sonar Pro, and every 1,000 toman is about 123 words of round trip. A job with one million input tokens and one million output tokens comes to 6,231,948 toman in total. Filling this model's 200,000-token window costs 207,732 toman on the input side alone, which is the real reason to keep conversation history short.

Its nearest relative in the catalogue is "perplexity/sonar", and choosing between those two is where most people hesitate. On a thousand-word request this variant works out about 9× more expensive (8,102 against 900 toman). The context windows differ too: 200,000 against 127,072 tokens. Maximum answer length differs as well: 8,000 against 114,364 tokens.

Perplexity has 5 models in our catalogue; the cheapest is Sonar at 900 toman per thousand words and the dearest Sonar Pro Search at 8,102. Among the less common parameters it accepts presence_penalty, top_k, web_search_options — all through the standard request body. It does not support include_reasoning, reasoning, response_format, tool_choice, which most models here do, so test before switching if your code relies on them. By context size the nearest option from another provider is Claude Haiku 4.5 at 200,000 tokens.

Where it makes sense: work where the quality of the answer matters more than its cost, pulling text and fields out of images, analysing a long document or codebase in one request.
