Proprietary(API-only)

Grok is proprietary and served only through the xAI API, grok.com and X, with no downloadable weights. This entry covers the model line only; the consumer chat app, grok-app, is a separate entry.

  xAI's model reference says "Grok 4.7. It is the most capable model we’ve built." and documents context, pricing and API model names only. Searched the body for self-host, download, open source and weights: none.

  xAI release notes announce "Grok 4.7, SpaceXAI's frontier model for coding, agentic tasks, and knowledge work, is now available on the xAI API as" grok-4.7, and still list "Grok 4.20 and Grok 4.20 Multi-agent are live". Searched the body for open weights, weights, download and open source: none, so no weight, code or license release accompanies either entry.

Grok is offered through the xAI API, grok.com and X. xAI publishes no per-model usage or user figure, so this reading is a judgment about those surfaces' reach rather than a measured count. The consumer chat app, grok-app, is a separate product.

  xAI's model reference headlines "Meet grok-4.6 ... Our flagship model for code and everything else - agentic tool calling", and lists grok-4.3, grok-4.5 and grok-4.6 alongside the older grok-4.20. No user, usage or per-model traffic figure appears anywhere on it. The URL now redirects to /developers/models.

  "Grok 3 Beta - The Age of Reasoning Agents"; the superseded release the earlier reading was based on. No usage or user figure published.

This score reads Grok 4.7, xAI's current flagship. It is well above the median on the Artificial Analysis index but behind the leading group of Claude, GPT-6, Gemini 4 and Muse Spark models, about eleven points under Claude Opus 5.5, which puts it a step below Claude Opus rather than among the frontier leaders.

  The leaderboard's embedded model records, ranked by intelligenceIndex, put Claude Opus 5.5 (Max) first at 57.62, then Claude Sonnet 5.5 (Max) 56.0, Claude Fable 5.1 (Max) 53.35, GPT-6 Astra (Max) 52.67, Gemini 4 Argon (High) 52.56, GPT-6.1 Sol (Max) 51.83 and Muse Spark 1.3 (Max) 48.09 among models not marked deprecated; Grok 4.7 (Xhigh) follows at 46.45, Gemini 3.8 Flash (High) at 40.93, K2 Horizon 375B A23B at 30.5 and Gemini 3.1 Pro Preview at 29.72.
