xAI Lists Grok 4.6: $2 Input, $6 Output, 500k Context Window

What's new

xAI quietly listed Grok 4.6 on 2026-08-12. It accepts text, images, and files as input and returns text — a practical multimodal setup for document-heavy or mixed-media workflows.

Pricing at a glance

• Input: $2.00 per 1M tokens
• Output: $6.00 per 1M tokens
• Context: 500k tokens

The input rate is competitive for a frontier-class model. The output rate at $6.00 per 1M tokens is where costs accumulate on verbose workloads — think long-form generation, detailed code output, or multi-step reasoning chains. If your app is read-heavy (retrieval, classification, summarisation), the $2.00 input price looks reasonable. If you're generating a lot, run the numbers against alternatives before committing.

The 500k context window: who actually needs it

500k tokens covers roughly 375,000 words — enough for large codebases, lengthy legal documents, or multi-document research tasks in a single pass. That's a genuine differentiator for enterprise or research use cases. For typical chatbot or single-document tasks, you're paying for headroom you won't use, so context size alone shouldn't drive the decision.

Worth switching?

Grok 4.6 slots into a crowded mid-to-upper tier. The file+image input support broadens its utility beyond text-only pipelines. Whether the pricing beats your current setup depends on your input/output ratio and volume — use our comparison tools to stress-test it.
