Claude Opus 5 matches Fable 5 coding at half the cost

If you gated agents on cost or on Fable 5's 30-day data retention, both objections just dropped.

JULY 26TH, 2026 · BY JONATHAN HILDEBRANDT

Anthropic shipped Claude Opus 5 on July 24 at $5 per million input tokens and $25 per million output, the same price as Opus 4.8. On OSWorld 2.0 computer use it beats Fable 5 at one-third the per-task cost, and on CursorBench 3.2 it lands within 0.5 percent of Fable 5's coding score at half the cost, per Anthropic's announcement.

Opus 5 keeps no retention window, which reopens healthcare, finance, and legal pipelines.

Quick Hits
• The open-weight AI letter doubled to 50 signatories. Fifty companies signed a July 24 letter urging Washington not to restrict downloadable models; Nvidia's Jensen Huang backed it with his first-ever X post, but Amazon and Anthropic did not sign. Read our take →
• A bipartisan bill would hand DHS an AI kill switch. The AI Kill Switch Act lets DHS order a slowdown or shutdown of any model trained on more than $100M of compute, with civil penalties up to $20M per day for defiance. Read our take →
• Cognition bought Poke, the first agent cleared for Apple Messages. Poke has moved more than 100 million messages since March; Cognition paid low nine figures, betting that personality is the moat in consumer agents. Read our take →
• Grok 4.5 is now a free Google Workspace add-on. A one-click install puts Grok inside Docs, Sheets, and Slides with Drive and Gmail context, following xAI's Microsoft 365 rollout the week before. Read our take →
• One downed line knocked 3 gigawatts of AI data centers off the grid. A July 22 transmission failure near Washington DC triggered a simultaneous 3-gigawatt disconnect in Northern Virginia; recovery took more than 10 minutes instead of seconds. TechCrunch →
