About Grok

Grok is the AI assistant from xAI, now part of SpaceX. It spans conversational chat (grok.com and Grok on X), agentic coding through Grok Build and Cursor, image generation via Grok Imagine, and voice. Its flagship Grok 4.6 (August 2026) followed Grok 4.5, and the family is positioned as an efficient, low-cost alternative to the frontier models from Anthropic, OpenAI and Google, tuned for coding, agentic tasks and knowledge work.

Grok 4.5 Review: Opus-Class Coding, Far Cheaper

4.4

SpaceXAI's Grok 4.5 isn't the smartest model on the board — Fable 5 and GPT-5.5 still edge it — but it delivers roughly Opus-class coding at ~4.2× fewer tokens and a third of the price, and leads on long agentic runs. The best value in frontier coding today.

Pros:
  • +Opus-class quality at far lower cost
  • +~4.2× fewer output tokens than Opus 4.8
  • +Leads SWE Marathon on long agentic runs
Cons:
  • -Not the top model — Fable 5 and GPT-5.5 edge it
  • -Heavy lock-in to Grok Build and Cursor
  • -Data-governance questions under Musk's xAI
