xAI: Grok 3
🇺🇸 xAI · Grok 3
Overview
xAI: Grok 3 is a large language model API from xAI, part of its Grok 3 model family. With $3.00 per million input tokens and $15.00 per million output tokens, it is a premium-tier model where output volume is the main cost to watch. Output tokens cost about 5× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. The 131K-token context window — around 197 pages of text — comfortably handles long documents, multi-file code, or extended conversations. All prices on this page reflect OpenRouter's routed rates and are re-synced automatically every day; confirm against the provider's official pricing before committing to production.
