LLM Platform
Grok
Also known as: xAI Grok, Grok-2, Grok-3
xAI's assistant, surfaced primarily inside X (formerly Twitter) and via the standalone Grok app. Distinctive for real-time access to the X firehose, which makes it the fastest LLM surface for current-events and live-trend queries, a different discovery shape from retrieval-grounded competitors.
What it is
xAI's assistant, surfaced inside X and as a standalone Grok app. It is distinctive for real-time access to the X firehose, which makes it fastest for current-events and live-trend queries.
Why it matters
It matters because its live connection to X makes it the surface where breaking, trending, and time-sensitive discovery happens, rewarding brands that are active and visible in real-time conversation.
How it works
You earn presence by maintaining an active, credible presence on X and by being part of the live conversation around trending topics, so your brand is in the firehose Grok draws on.
When it applies
Prioritise it for time-sensitive, current-events, or trend-driven queries, and when your audience is active on X.
Examples
- Grok answers a question about a breaking industry development and references your brand's post.
- A trending-topic query surfaces your company as part of the live conversation.
- A user asks Grok for real-time reaction and your account is among the cited voices.
How it is measured
- Frequency of mention in answers to trending and current-events queries.
- Reach and engagement of your brand's activity on X.
- Recency: how quickly your content enters Grok's real-time answers.
- Share of voice within live conversation on your category topics.
