Verdict

When to choose each

Gemini 4 Carbon

Where it leads

  • Higher Arena Text score, 1528 Elo vs 1415 Elo
  • Cheaper cached input, $0.10 vs $0.50 per 1M tokens

Best for

  • Finding, validating and patching vulnerabilities, for teams in Google's Fairwind Program
  • Long-horizon engineering over very long inputs, once access opens

Watch out for

  • Limited access: Google gives it first to a small group of cyber defenders, then to more trusted partners through its Fairwind Program, which governments, healthcare providers and telecoms apply to; there is no public API or app access yet
  • The $2 and $10 rates are introductory, with cached input 95% off; after an introductory period Google has not dated, $4 input and $20 output per 1M tokens apply
  • 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%)
  • Google publishes no context window or output limit for Carbon yet

GPT-4.1

Where it leads

  • Lower price per 1M output tokens, $8 vs $10

Best for

  • Long-context API trials using text and image inputs

Watch out for

  • Not in the pinned LiveBench snapshot; its independent scores here come from Epoch AI's own GPQA Diamond, FrontierMath and SimpleQA Verified runs
