Grok API FAQ
Answers to critical questions regarding context caching, thinking token calculations, and platform rate-limiting.
The Grok API (developed by xAI) provides developers with programmatic access to state-of-the-art language and vision models, including the flagship Grok 2, Grok 2 Vision, and high-speed Grok 2 Mini models, known for advanced real-time reasoning capabilities.
Pricing is calculated on a Cost-Per-Million (CPM) tokens model. Fees are divided into input tokens (with 50% discounts for cached prompts) and generated output tokens. Prices start as low as $0.60/M input tokens and $2.40/M output tokens for Grok 2 Mini.
Yes. xAI supports context/prompt caching for Grok API calls. When matching preambles, system instructions, or long document contexts are reused across consecutive requests, cached input tokens receive a 50% discount on standard rates.
X Search Grounding integrates xAI’s real-time information engine to query real-time facts and conversations before generating responses. In the API, enabling search grounding adds an additional surcharge of $0.50 per million input tokens.
At $2.00 per million input tokens and $10.00 per million output tokens, Grok 2 is highly competitive with major Western frontier models while offering state-of-the-art performance on code generation and multi-step reasoning tasks.
