Anthropic released Opus 5, a mid-tier AI model positioned at half the cost of its flagship Fable 5 while approaching similar capabilities for office work and programming tasks. The model shows faster iteration cycles and improved safety profiles against exploitation and misuse compared to prior versions.

◆ ◆ The Wire takeaway
If you're selling AI-powered tools to office workers or developers, your unit economics just shifted: the cost-per-inference for capable models halved. You can now afford to embed Opus 5 into products that wouldn't work at Fable 5 pricing, and your customers can afford higher query volumes without hitting budgets.
