Compare Grok 4.5 with others

Grok 4.5 (July 2026) is xAI's smartest model, built for coding, agentic tasks and knowledge work and trained alongside Cursor. It's fast (~80 tokens/sec), roughly 2× more token-efficient than comparable leading models, and priced aggressively at $2/$6 per 1M tokens.

Best for

  • End-to-end app building from a single prompt
  • Agentic coding in editors (free in Cursor, all plans)
  • Knowledge work — Excel models, slides, docs (Grok Build)
  • Budget-conscious teams wanting frontier-ish quality

How it compares — and the India angle

  • Best value among the July-2026 frontier models: $2/$6 per 1M with ~2× token efficiency means big savings for Indian devs.
  • Free for a limited time in Cursor and Grok Build — great way to try it before paying.
  • Note: not yet available in the EU (India is fine); available via Grok Build, Cursor and the xAI console.

How to access

API $2 / 1M input, $6 / 1M output. ~80 tokens/sec, ~2× token efficiency. Via Grok Build, Cursor (all plans, free for now) and the xAI console. Not yet in the EU.
