xAI pricing — frequently asked questions

What is xAI's pricing model?

xAI bills the Grok developer API per million tokens across a good-better-best model ladder — the grok-4.5 flagship at $2 input / $6 output and the still-live grok-4.3 at $1.25 / $2.50 (cached $0.20) — with agentic tools (web search, X search, code execution) metered separately at $5 per 1,000 calls. A separate consumer Grok app is freemium ($0 Free, $30/mo SuperGrok on Grok 4.5).

How much does the Grok API cost per million tokens?

Short-context rates: grok-4.5 (500k context) is $2.00 per 1M input and $6.00 per 1M output, cached input $0.30; grok-4.3 (1M context) is $1.25 / $2.50 (cached $0.20); grok-build-0.1 is $1.00 in / $2.00 out. Once a request's prompt reaches 200k tokens the whole request bills at the long-context column — $4.00 / $12.00 for grok-4.5 and $2.50 / $5.00 for grok-4.3. Media and voice are priced separately (e.g. images from $0.02, TTS $15.00 per 1M characters).

Does xAI offer a free tier?

Yes, on two surfaces. The consumer Grok app has a Free plan at $0/month with real-time web and X search, voice mode, and connectors. On the API side, xAI ran $25/month in free credits during the 2024 public beta and continues to offer promotional credits.

How does Grok API pricing compare to OpenAI and Anthropic?

At $1.25 in / $2.50 out, grok-4.3 undercuts most frontier flagships on output tokens, while the July 2026 grok-4.5 flagship ($2 / $6) adds a premium intelligence rung above it. Grok 4 launched in July 2025 at $3 / $15 per 1M tokens; xAI then cut per-token rates dramatically before grok-4.5 became its first flagship priced above its predecessor — positioning Grok as price-aggressive at the value rung and competitive at the frontier.

Is this xAI pricing calculator free and accurate?

Yes — it's completely free with no signup. It uses the latest publicly available xAI pricing (verified July 2026). Actual costs may vary with volume discounts or enterprise terms — always confirm on xAI's official pricing page.
