Anthropic Just Killed Their Own Flagship. Opus 5 Is Half The Price. #Shorts

On July 24, 2026, Anthropic released Claude Opus 5 — the successor to Opus 4.8 — at HALF the price of their own flagship Fable 5. Same $5 in / $25 out per M tokens.

THE NUMBERS:
• Frontier-Bench v0.1: 43.3% (Fable 5: 33.7%, Opus 4.8: 21.1%)
• ARC-AGI-3: 30.2% (3x next-best)
• OSWorld 2.0: 70.6%
• GDPval-AA Elo: 1861
• AutomationBench: 26.0%
• 1M token context standard · Thinking on by default

Cursor co-founder Sualeh Asif called it 'near Fable 5 intelligence at Opus speed and cost.'

Migration is one line: model="claude-opus-5". Same API surface as Opus 4.8. Available on Claude API, Claude.ai, Claude Code, Claude Cowork, Bedrock, Google Cloud, and Microsoft Foundry.

THE GOTCHA: Mythos 5 still owns cybersecurity + biology. GPT-5.6 Sol still wins DeepSWE v1.1. And thinking:{'type':'disabled'} + effort=xhigh now returns HTTP 400.
