Anthropic launches Claude Opus 5, saying it nears Fable 5 on many tasks
The Verge AI · rss · 2026-07-25
Anthropic has released Claude Opus 5, saying it comes “close” to Claude Fable 5 in many domains and is significantly better at complex coding tasks.
- The launch comes weeks after Anthropic’s run-in with the U.S. government and days after an OpenAI security incident that had the industry talking.
- The company is positioning Opus 5 as a major upgrade, especially for harder software engineering work.
- The announcement also lands in the shadow of Fable 5, the public-facing Mythos-class model that was briefly taken offline and later returned with tighter cyber safeguards.
