| Claude Fable 5.1Anthropic | 67.4%Reported settings & sourceAnthropic reported configuration; adaptive thinking at max effort, default sampling, five-trial mean unless section specifies otherwise; context at most 1M. Comparator configuration follows cited prior card or board. 113 tasks; original hidden-test grading. Fable is the safeguarded deployed configuration; selected tasks may use disclosed Opus fallback, except evaluations explicitly counting safety blocks as failures.

| Claude Opus 5.5Anthropic | 74.2%Reported settings & source113 long-horizon tasks; five-trial mean. Section 8.3 does not state reasoning effort. Provider-published lab self-report from the Claude Opus 5.5 system card (SHA256 7311c9c6bbb16d012f1c12c7418b05949fcf7ae3e30d2c40f22050074b2a7378). Not an independent board. Effort is not stated in this section, so it is not copied from the Table 8.1.A max-effort default. Comparison limit: Provider-published lab self-report. Shown as a labeled claim and not admitted as a matched board comparison. Claude Opus 5.5 System Card · section 8.3 · reviewed 2026-09-22 | Claude Opus 5.5 System Card | lab self-report | 2026-09-22 |
