xAI (Grok) Pricing
xAI (Grok) charges from $0.500 per 1 million output tokens, depending on the model. Grok 3 Mini is the cheapest at $0.500/1M output and $0.300/1M input; its current flagship Grok 4.7 costs $6.00/1M output. The largest context window is 2.0M tokens (Grok 4 Fast). Prices are USD, current as of October 12, 2026.
xAI prices Grok per million tokens, with the fast and mini variants sitting well below the flagship. Context windows are large across the lineup, which makes prompt size less of a cost lever here than output length.

A dash in the batch column means our catalog carries no published batch rate for that model — not that the model has no batch tier. Batch coverage in the upstream pricing data is uneven.
Frequently asked questions
How much does xAI (Grok) cost per 1M tokens?
xAI (Grok) pricing starts at $0.500 per 1 million output tokens (Grok 3 Mini) across 43 models, with its current flagship Grok 4.7 at $6.00. Older premium models in the catalog list higher. Rates current as of October 12, 2026.
What is the cheapest xAI (Grok) model?
Grok 3 Mini is the cheapest xAI (Grok) model on output tokens at $0.500 per 1M, while Grok 4 Fast is cheapest on input at $0.200 per 1M. Which wins for you depends on your input-to-output ratio.
What is the largest xAI (Grok) context window?
Grok 4 Fast has the largest context window in the xAI (Grok) catalog at 2.0M input tokens, with up to 16K output tokens per response.
Does xAI (Grok) support prompt caching?
Yes. Grok 4.20 (Non-Reasoning) reads cached input at $0.200 per 1M tokens, against $1.25 per 1M uncached. Caching pays off when a long system prompt or document is reused across many requests.
Does xAI (Grok) offer batch pricing?
Yes — 10 xAI (Grok) models in this catalog publish a discounted rate for asynchronous batch jobs, at 20% off output tokens. Grok 4.3 bills $2.00 per 1M output in batch against $2.50 synchronously. Batch trades real-time responses for the lower rate, so it suits backfills, evaluations and bulk enrichment rather than user-facing calls.
Which xAI (Grok) models support reasoning or vision?
The xAI (Grok) catalog includes 7 reasoning models, 8 vision models, 7 with tool calling. Reasoning models bill their internal thinking as output tokens, so they cost more per visible response than the headline rate suggests.
How do I calculate my actual xAI (Grok) bill?
Multiply your input tokens by the input rate and your output tokens by the output rate, both per million, then add retries and any conversation history resent on each turn. Calcaas does this against your real usage pattern and shows the margin left at your price point.

What will this actually cost you?
Per-token rates only tell you half the story. Calcaas multiplies them by your real usage — prompt size, response length, retries and conversation history — then shows the margin left at your price point.
