Google reported 71.0% for Gemini 4 Carbon on CWE-bench in its October 28, 2026 announcement. These external-benchmark evaluations were without guardrails; exact methods and samples remain unqualified.
Limits: Provider-reported result from Google’s public narrative, not an independently verified benchmark-owner result or a reproduced run. The selected model label is Gemini 4 Carbon; exact evaluated checkpoint, API identifier, version/build and configuration are not disclosed in the inspected narrative. Benchmark revision, task subset, sample size, execution date, harness, prompt/sampling protocol, tool/reasoning/token budgets, aggregation, pass-k and uncertainty remain unknown. The reported result concerns vulnerability patching; no broader capability rank, matched head-to-head, guarded-deployment equivalence or operational success is established. Carbon remains a restricted announced rollout in the selected model record. This percentage does not establish public API availability, general availability or account access.
