Products, models and their relationships
The kind labels distinguish an application or service from a model family. Availability and entitlements differ across these surfaces.
model family
Grok models
The models developed by SpaceXAI. They are separate from the assistant, coding and media applications through which people use them.
Product relationship sourceapplication
Grok assistant
The conversational application, including distribution linked to X. An X account by itself does not establish that its owner uses Grok.
Product relationship sourcedeveloper api
Grok API
Programmatic model access for developers. The September 21, 2026 Grok 4.7 announcement included the API among its launch routes.
Product relationship sourcecoding agent
Grok Build
The coding-agent product named as a Grok 4.7 launch route. It is a way to work with the model on coding tasks, rather than the model's name.
Product relationship sourceongoing agent product
Grok Bot
The ongoing-agent product listed in the official product navigation, separate from the conversational assistant.
Product relationship sourceimage and video tool
Imagine
Image and video tooling in the Grok lineup. It serves media work, separate from the underlying Grok model family.
Product relationship sourcespeech tool
Voice
Speech tooling in the product lineup, separate from the assistant and image/video products.

Who uses it, and what the numbers mean
- Developers and coding teams evaluating the Grok API or Grok Build, with launch route, model access and integration permissions checked for their workflow.
- Consumers evaluating conversational or X-linked Grok workflows, without treating X membership as Grok adoption or assuming every agent product has the same access.
These are dated vendor-reported figures. Populations and units differ; this is not a market-share ranking.
Approximately 600 million Monthly active users across X and Grok apps combined
· Combined X and Grok-app audience reported by xAI.
Not Grok-only MAU; no separately deduplicated Grok population established. Grok-only MAU is unavailable in this research.
