Anthropic shipped Claude Opus 5 today, and the headline number is the one they refused to raise.
Same $5 in, $25 out as Opus 4.8. Half of what Fable 5 charges. And the performance sits close enough to the frontier that the tier below it just became the default for almost everyone: ▫️ Frontier-Bench v0.1: 43.3%, against Opus 4.8’s 18.7% and Fable 5’s 33.7% ▫️ CursorBench 3.2: within 0.5% of Fable 5’s peak, at half the cost per task ▫️ ARC-AGI 3: three times the next-best model, on a test built so memorization fails ▫️ OSWorld 2.0: past Fable 5’s best result at a third of the cost The customer numbers hit harder than the benchmarks. Harvey matched Opus 4.8’s max-reasoning quality using 26% fewer tokens. Zapier’s churn workflow went from failing every prior model to 100%. A trading firm hit its best Opus score on a seventh of the reasoning tokens. Here is the free insight: this is a price-per-outcome launch wearing a model launch costume. Anthropic held the sticker price flat and moved everything underneath it. Intelligence up, tokens down, safety blocks down 85%, speed up 2.5x in Fast mode. Your bill for the same work drops even though the price page stayed identical. That only happens if you drive it correctly. Most people will run it on defaults and leave the upside sitting there.
