This page compares Gemini 3 Pro (Google) and Grok 4 (xAI) using the latest snapshots we have as of Aug 1, 2026. On preference Elo, Gemini 3 Pro is ahead by 64 points (1,552 vs 1,488; seed-bootstrap (Aug 1, 2026)). On SWE-bench coding, Gemini 3 Pro resolves 72.4% versus 58.6% (seed-bootstrap (Aug 1, 2026)). Grok 4 streams faster (98 tok/s) while Gemini 3 Pro is the cheaper output token ($5/1M). Gemini 3 Pro has the larger context window (2M tokens). Every cell below is a dated snapshot from a named public source — we do not invent missing scores, and we do not run SWE-bench ourselves.

Frequently Asked Questions

Which is better overall, Gemini 3 Pro or Grok 4?: Gemini 3 Pro has the higher preference Elo in our latest snapshot (1,552). “Better” still depends on coding, price, and latency — see the table.
Which is better at coding, Gemini 3 Pro or Grok 4?: Gemini 3 Pro leads SWE-bench at 72.4% vs 58.6%. SWE-bench is one harness, not your repo.
Which is cheaper to run in production?: Gemini 3 Pro output tokens are $5/1M versus $15/1M. Input prices and retry rates still move the real bill.
Which is faster, Gemini 3 Pro or Grok 4?: Gemini 3 Pro has the lower time-to-first-token (220 ms vs 230 ms). Tokens/sec is a separate column if you care about long completions.
Which has the larger context window?: Gemini 3 Pro accepts 2M tokens versus 256k.
Can I self-host either model?: Neither model is marked open-weights here. You are comparing hosted APIs.
Are these scores from CompareLLM’s own evals?: No. V1 aggregates public leaderboards (and optional first-party latency pings). Each cell names its source and date. Read /methodology.
What does preference Elo mean on this page?: Preference Elo is a crowd vote from LMArena / Arena. People see two hidden answers and pick the one they like more. The model that wins more often gets a higher Elo. That means people preferred it — not that it passed a school test. It is not SWE-bench, not accuracy, and not a number we invent. Gemini 3 Pro and Grok 4 Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
