Verdict

When to choose each

Gemini 4 Carbon

Where it leads

  • Higher Arena Text score, 1526 Elo vs 1442 Elo
  • Higher Arena WebDev score, 1768 Elo vs 1641 Elo
  • Higher GPQA Diamond score, 96.5% vs 92.7%
  • Higher FrontierMath Tiers 1-3 (v2) score, 90.5% vs 53%
  • Higher SimpleQA Verified score, 77.7% vs 56%
  • Larger context window 1,048,576 vs 500,000 tokens
  • Accepts image, audio and video input
  • Cheaper cached input, $0.10 vs $0.50 per 1M tokens

Best for

  • Finding, validating and patching vulnerabilities
  • Long-horizon engineering and research over very long inputs

Watch out for

  • Generally available in the Gemini API since November 10, 2026, on the paid tier only (there is no free tier), after two weeks open only to cyber defenders in its Fairwind Program
  • The $2 and $10 rates are introductory and end on November 30, 2026: from December 1, input, output and cached input double, to $4, $20 and $0.20 per 1M tokens (Batch from $1 and $5 to $2 and $10)
  • In Google's own table it trails GPT-6 Astra on FrontierSWE 2 (61.2% against 65.5%) and Claude Opus 5.5 on OSWorld-2.1 (81.5% against 87.2%)
  • A request returns at most 65,536 output tokens by default; longer outputs, up to 1,048,576 tokens, need Google long-decode mode
Full Gemini 4 Carbon profile

Grok 4.7

Where it leads

  • Lower price per 1M output tokens, $6 vs $10

Best for

  • Output-heavy generation under the 200,000-token prompt line
  • A cheaper alternative to the frontier tiers where 500k of context is enough

Watch out for

  • The long-prompt threshold is 200,000 tokens, the lowest of any model here, and reaching it doubles input and output for the entire request
  • xAI's model page does not state a maximum output for Grok 4.7, so it is recorded as unknown rather than inferred
  • That page does not explicitly list image input for this model either, so it is catalogued as text-only
