GPT-6 Astra vs Opus 5.5: 5x Reasoning Tokens for 5 Points, Is Opus Actually Smarter?
VraserX · x · 2026-10-06
An X debate is raging over whether Claude Opus 5.5 is objectively smarter than GPT-6 Astra. Critics argue the claim cherry-picks benchmarks: Astra leads on FrontierMath Tiers 1–3 (93.7 vs 91.2) and Tier 4 (97.6 vs 95.0), and wins AutomationBench, Terminal-Bench Science, and tops EyeBench — all while being far more token-efficient.
The key counterpoint: Opus 5.5 Max scores 58 vs Astra's 53, but burns roughly 5x the reasoning tokens. At comparable inference budgets, that edge largely collapses — "more compute leasing to slightly higher scores isn't proof of a smarter model."
