Anthropic launched Opus 5, achieving near-parity with its flagship Fable 5 model at half the cost, positioning it for everyday office and programming tasks. The efficiency upgrade reflects rapid model iteration and addresses the cost-performance tradeoff as Fable 5 faces export restrictions due to security concerns.

◆ ◆ The Wire takeaway
If you've been waiting for a Claude model cheap enough to replace GPT-4o in production, Opus 5 is live now and half Fable 5's price. Fable 5's export freeze just became your sales cycle — call every customer running restricted deployments and offer them the performance at cost.
