Usage/token API pricing (no subscription tiers). All prices in USD. IMPORTANT: the requested page itself (https://docs.x.ai/docs/models) currently contains NO price table — it only carries model-selection guidance, model aliases, image-input limits, and knowledge-cutoff notes (page last updated May 29, 2026). The verified prices above were extracted from the companion canonical pricing page https://docs.x.ai/docs/pricing (last updated May 27, 2026), which explicitly states "for per-model details, see the models page" — they are the same xAI docs set. Note: an automated WebFetch summary of the /docs/models URL fabricated a pricing table that did not exist on that page, so figures were re-verified against the raw /docs/pricing scrape. Batch API: text/language models billed at 20%-50% off standard rates (image/video generation billed at standard rates in Batch). Image Understanding, X Video Understanding, and Remote MCP tools are token-based (no flat invocation fee). Prices subject to change.

Rate & usage limits ● livestructure only

This provider doesn't publish numeric request/token limits on its docs — only the usage-tier structure below. Your actual limits appear in your account dashboard.

Tier Notes
Tier 0 Default tier at $0 spend. Per-model limits vary (e.g., grok-4.7: 150 RPS / 50M TPM; grok-4.5: 150 RPS / 50M TPM; grok-imagine-image: 6 RPS). RPS derived from RPM/48 with minimum 2. Per-second (RPS) and tokens-per-minute (TPM) limits shown per model.
Tier 1 $50+ cumulative spend. Per-model limits vary (e.g., grok-4.7: 172 RPS / 53M TPM; grok-imagine-image: 12 RPS).
Tier 2 $250+ cumulative spend. Per-model limits vary (e.g., grok-4.7: 208 RPS / 60M TPM; grok-imagine-image: 25 RPS).
Tier 3 $1,000+ cumulative spend. Per-model limits vary (e.g., grok-4.7: 312 RPS / 74M TPM; grok-imagine-image: 50 RPS).
Tier 4 $5,000+ cumulative spend. Per-model limits vary (e.g., grok-4.7: 500 RPS / 100M TPM; grok-imagine-image: 100 RPS).
Enterprise Available on request. Contact sales@x.ai for enterprise-grade capacity and limits beyond Tier 4.

Limits are per-model and specified as RPS (requests per second) and TPM (tokens per minute). No daily limits (RPD) published. Voice/Audio endpoints use concurrent sessions (CST) instead of TPM for some models. Personalized limits viewable in xAI Console dashboard only.
