Grok 4

xAI's flagship model. Released July 9, 2025; grok-4.3 is a subsequent deployment version of the same generation. Differentiated primarily by X (Twitter) data access via tool use and strong current-events accuracy — no other frontier model has comparable integration with a live social/news feed.

Key Differentiator

Best current-events accuracy of any frontier model, by a meaningful margin. If the task requires knowing what happened last week, what people are saying about a topic right now, or synthesizing information from recent public discourse, Grok has a structural advantage. This comes from access to X data through an explicit search tool, not passive always-on real-time awareness.

X Search: How It Actually Works

Grok does not have always-on real-time awareness of X. X Search is a tool that must be explicitly activated — either by the user or by the model when it determines a query benefits from live data. When active, it can retrieve live posts, trending topics, and public sentiment from X. Tasks that don't invoke the tool use standard model knowledge up to the training cutoff.

Capabilities

  • X Search tool — live posts, trending topics, public sentiment (requires activation)
  • Competitive coding and reasoning benchmarks
  • 1M token context window
  • Image understanding

API Pricing (grok-4.3)

  • Input: $1.25 per million tokens
  • Output: $2.50 per million tokens
  • Context window: 1M tokens

Strengths

  • Real-time information via X Search: Unmatched when the tool is active. The X integration is a genuine moat.
  • Current events synthesis: Good for monitoring, trend analysis, and tasks that benefit from social signal
  • No censorship constraints: More willing to engage with edgy or controversial prompts than Anthropic/OpenAI models
  • Competitive on standard reasoning benchmarks

Weaknesses

  • Smaller developer ecosystem than OpenAI/Anthropic — fewer third-party integrations
  • API access has had reliability and availability issues
  • X data integration creates bias toward X-heavy discourse (tech/crypto/politics skewed)
  • Less hardened for agentic tool-use compared to claude-sonnet-4-6
  • Pricing and availability changes frequently

Use Cases

Best for: market monitoring, social listening, current events summarization, crypto/finance tasks where recency matters, research on rapidly developing topics.

Not the default for: pure coding tasks (Claude or Gemini lead there), math-heavy work (deepseek-r1), long-document analysis (gemini-2-5-pro), or production agentic pipelines (ecosystem immaturity).

Access

Available via xAI API and Grok.com. API access requires xAI developer account. X Premium subscription provides Grok access within the X interface.
