Grok 4.6 API Pricing
Grok 4.6 is SpaceXAI's previous frontier model for coding, agentic tasks, and knowledge work, released August 12, 2026 and followed on September 21, 2026 by Grok 4.7, which launched on the same rate card. The pricing page lists $2.00/M input, $0.50/M cached input, and $6.00/M output for prompts under 200K tokens. At or above 200K every rate doubles — $4.00 / $1.00 / $12.00 — and the higher rate applies to the whole request, not just the tokens past the line.

Live calculator pre-loaded with Grok 4.6's sub-200K rates from SpaceXAI's pricing page. Reasoning effort is configurable across low, medium, high (default) and xhigh, and reasoning tokens bill at the output rate. Note the threshold: send a prompt of 200K tokens or more and every rate in this calculator doubles.

This is a chars-per-token approximation, not a real tokenizer. Actual tokens vary by language, code density, and tool-call overhead — counts are typically ±10–20% off for English prose, more for code or non-Latin scripts. For exact billing, use the vendor's official tokenizer.

Frequently asked.
Grok 4.6 pricing questions, with SpaceXAI's token rates separated from the long-context threshold and cache assumptions.
Q · 01 What is Grok 4.6's API price? +
grok-4.6 at $2.00/M input, $0.50/M cached input, and $6.00/M output for prompts below 200K tokens. These are USD prices per 1M tokens.Q · 02 Why does Grok 4.6 have two sets of prices? +
$4.00/M input, $1.00/M cached input, and $12.00/M output. The trigger is the prompt reaching 200K tokens, and the higher rate then applies to every token in that request — not only the tokens beyond 200K. A 199K-token prompt and a 201K-token prompt therefore differ in cost by roughly 2x, not by 1%.Q · 03 Is Grok 4.6 more expensive than Grok 4.5? +
$2/M input and $6/M output. The difference is cache. Grok 4.5's cached input was cut to $0.30/M on the day Grok 4.6 launched, while Grok 4.6 reads cache at $0.50/M. Under our standard blend (92% input, 82% cache hits) that puts Grok 4.6 at $1.19/M effective against Grok 4.5's $1.04/M — so on cache-heavy agent loops the older model is currently the cheaper one.Q · 04 What context window does Grok 4.6 have? +
500,000 tokens, the same window as Grok 4.5. Grok 4.3 and the Grok 4.20 variants are listed at 1M, so Grok 4.6 is not the longest-context Grok. Grok 4.7 keeps the same 500K window.Q · 05 Does Grok 4.6 support batch pricing? +
Q · 06 Where can I call Grok 4.6? +
us-east-1, us-west-2 and us-central-1, with rate limits of 150 requests per second and 50M tokens per minute. It supports function calling, structured outputs, and reasoning at low, medium, high (default), and xhigh effort. Grok 4.6 is also served on SpaceXAI's US regional endpoint, us.api.x.ai, which keeps inference in the United States and bills every rate at 1.1x.
