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-4.6: 150 RPS / 50M TPM). View personalized limits in console. |
| Tier 1 | $50 cumulative spend. Per-model limits scale exponentially (e.g., grok-4.6: 172 RPS / 53M TPM). |
| Tier 2 | $250 cumulative spend. Per-model limits increase further (e.g., grok-4.6: 208 RPS / 60M TPM). |
| Tier 3 | $1,000 cumulative spend. Per-model limits continue to scale (e.g., grok-4.6: 312 RPS / 74M TPM). |
| Tier 4 | $5,000 cumulative spend. Highest published tier (e.g., grok-4.6: 500 RPS / 100M TPM). |
| Enterprise | Available on request via sales@x.ai. Custom limits negotiated. |
Limits are per-model and expressed as RPS (requests per second) and TPM (tokens per minute). Exact limits vary by model. All limits are viewable only in xAI Console dashboard; numeric limits not published here except in per-model table. RPS is derived from RPM/60 to prevent burst spending.
