Grok 4.6 (batch) 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 Grok 4.6 (batch) good for?

Grok 4.6 (batch) is one of xAI's models. Put "x-ai/grok-4.6:batch" in the model field and the rest of your code stays as it is. Grok 4.6 (batch) keeps 500,000 tokens in view at once, and that number is what caps the conversation history in your product. A single response can run to 450,000 tokens. On price it sits in the "mid-range" band — cheaper than 119 and dearer than 278 of the other paid models in the catalogue.

What it can do beyond plain text: it reads images directly, which makes it a real option for invoices, forms and screenshots; it takes files such as PDFs as input; it supports tool calling, so it can invoke your own functions with valid arguments; it returns schema-valid JSON through response_format, ready to hand to your code; it has a reasoning mode that pays off on multi-step problems, maths and debugging. All of it works through the standard parameters of the official OpenAI SDK — no custom client, no wrapper. Keep in mind that reasoning tokens are output tokens and do appear on the bill.

Pricing is 553,951 toman per 1M input tokens and 1,661,853 per 1M output tokens. A 1,000-word round trip on Grok 4.6 (batch) lands near 2,881 toman. It supports cached input: repeated context is billed at 138,488 toman per 1M, which matters a lot if your system prompt is long. 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 Claude Haiku 4.5: Grok 4.6 (batch) works out about 10% more expensive, and its context window is larger. 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 35 thousand-word requests on Grok 4.6 (batch), and every 1,000 toman is about 347 words of round trip. A job with one million input tokens and one million output tokens comes to 2,215,804 toman in total. Filling this model's 500,000-token window costs 276,975 toman on the input side alone, which is the real reason to keep conversation history short.

This id gets confused with "x-ai/grok-4.6", because the underlying model is the same. The difference is the suffix: "batch" against the standard variant. On a thousand-word request this variant works out about 17% cheaper (2,881 against 3,601 toman).

xAI has 11 models in our catalogue; the cheapest is Grok 4.3 (batch) at 1,350 toman per thousand words and the dearest Grok Latest at 3,601. Among the less common parameters it accepts logprobs, reasoning_effort, top_logprobs — all through the standard request body. By context size the nearest option from another provider is Dots3-Note Preview (free) at 512,000 tokens.

Good fits: product chatbots and internal assistants, where cost and quality have to balance, logic puzzles and code review, pulling text and fields out of images, agents that reach out to APIs and databases, extracting data against a fixed schema, analysing a long document or codebase in one request.
