【AI Compute Leaderboard】Where does the world champion from six months ago rank today? Claude Opus 5.5 remains at the top

This week's two chart-toppers: Intelligence chart – Claude Opus 5.5 (Max, Default Fallback) (57.6 points), Coding chart – Claude Fable 5.1 (Max, Default Fallback) (81.6 points). See table for up/down arrows.

Full score is 100, but don't be fooled by the number: the test suite includes hellish benchmarks like Humanity’s Last Exam, and 57.6 points is already the highest in human history.

Each lab's strongest: Current status + two yardsticks

3/6 months ago is the baseline; this week + 1 month ago is the current status, telling you who's stagnating and who's parachuting in.

Can't beat the 6-month-ago champion = falling behind the times; beating the 3-month-ago champion counts as catching up to the era.

Passing list: Who caught up to the era? Who's free to use?

★ = passed the 3-month strong line as well; ✅ = this version free; ◐ = free version in same series; — = none. Free access mostly limited-time, as of publication date.

Cost-performance: 6-month version vs 3-month version

6-month version entry > adequate line, pass strong line ×1.5; 3-month version entry > strong line, same tier comparison without multiplier.

Compute timeline: What chips were the models scoring now trained on?

Chip/ArchitectureAnnouncedShipping status
B200 (Blackwell)March 2024 GTCMature large-scale commercial use, mainstay of major clouds
B300 (Blackwell Ultra)Late 2024/early 2025 spec freezeShipping ramping up, DGX B300 available for purchase, clouds rentable by the hour
Vera Rubin (R100+HBM4)2025/2026 GTC finalizedMass production mid-2026, partner deliveries H2, not yet widely commercial

Pattern: 9–12 months from start of shipping is the next AI compute upgrade peak. B300 only rolling out at scale this year, earliest year-end to see next-gen models trained on it; Rubin-trained stuff, 2027 before we see it.

Other quick updates

・Most expensive: The most expensive input on the whole chart, expensive and weak – named as not recommended; current flagship price US$10.
・Specialist king: Those that never passed Intelligence line but are world-class in Coding, code-writing specialists.
