Capability & preference

General capability · ECI

A cross-benchmark capability estimate. Index points, not a percentage; intervals show uncertainty.

Claude Opus 5.5 168.4* Claude Opus 5.5 · 95% interval 165.5–171.5

Human preference · Arena

Overall text preferences from head-to-head votes. Not factual accuracy or a task-success rate.

Claude Opus 5.5 1515.8 Claude Opus 5.5 (High) · 95% interval 1509.2–1522.4 · 11,415 votes · 2026-10-28

Model performance

Radar task score: four tests, equal weight. An experimental summary of these tasks, not a universal intelligence rating.

Claude Opus 5.5

Radar task score

81.3* / 100

4/4 core tests · experimental v1

8 benchmark results for this configuration

Scientific reasoning

GPQA Diamond · 25%

Expert-written science questions; strict multiple-choice scoring. Chance accuracy is 25%.

Claude Opus 5.5 90.6*% Approx. 95% interval: 86.8–94.4%

Novel problem solving

Mystery Game Puzzles · 25%

Best-next-move puzzles in an undisclosed game variant. A narrow reasoning test, not general intelligence.

Claude Opus 5.5 71.0*% Approx. 95% interval: 62.1–79.9%

Advanced mathematics

FrontierMath Tiers 1-3 · 25%

Private v2 mathematics problems with Python tools. Earlier versions and Tier 4 are excluded.

Claude Opus 5.5 91.2*% Approx. 95% interval: 87.9–94.5%

Factual answers

SimpleQA Verified · 25%

Correct factual answers under a guessing prompt, graded by a model. Not a hallucination or abstention score.

Claude Opus 5.5 72.2*% Approx. 95% interval: 69.4–75.0%

Competition mathematics

OTIS Mock AIME 2024-2025 · Separate result

Competition problems with model-extracted answers checked against an exact key. Earlier grading procedures are excluded.

Claude Opus 5.5 100.0*% Uncertainty not available

Research mathematics

FrontierMath Tier 4 v2 · Separate result

The hardest private FrontierMath problems, corrected v2 set, with Python tools. Separate from Tiers 1-3 in the core score.

Claude Opus 5.5 95.0*% Approx. 95% interval: 86.9–100.0%

Visual spatial reasoning

Furniture Assembly · Separate result

Assembly-error detection from photos and manuals, with zoom and Python tools. Uses model-assisted grading; not a general vision score.

Claude Opus 5.5 83.3*% Approx. 95% interval: 74.1–92.6%

Long-horizon computer use

SpireClimb · Separate result

Equally weighted win rates in two Slay the Spire games via screenshots and controls. Fixed game versions; not a general desktop success rate.

Claude Opus 5.5 3.3*% Approx. 95% interval: 0.5–6.2%

Bars show reported task scores. Whiskers are approximate 95% intervals where standard errors are available. Different reasoning budgets are not equal-cost tests. Missing results are never zero.

Recorded results

Only the same benchmark, version, workload, scenario and unit share a row. Missing results are not zero. System results include the full submitted hardware and software configuration.
