These two models do not currently report scores on any of the same benchmark suites, so there is no like-for-like capability comparison to show. Rather than pad the page with one-sided numbers, the benchmark leaderboards list every score we do hold.

What each model is for

Gemini 3.6 Flash

Google · Balanced

Google's current workhorse model, released July 2026 as the practical successor to 3.5 Flash rather than the long-delayed 3.5 Pro. It improves on coding, knowledge work and multimodal handling while reducing token usage by up to 17%, which makes it cheaper to run than its predecessor on the same task even before the headline rate is compared.

  • Up to 17% fewer tokens per task than 3.5 Flash
  • Coding and knowledge work
  • Multimodal input including audio and video
  • 1M-token context

Grok 3

xAI · Frontier

xAI's flagship Grok. Real-time access to the X firehose makes it strong on current events and live commentary.

  • Real-time X data
  • Less filtered tone
  • Strong general reasoning
