Opus 4.5

Opus 5 lands at the same price as Opus 4.8 — and the price is the point

Anthropic has released Opus 5, its latest AI model, maintaining the same pricing structure as its predecessor at $5 per million input tokens and $25 per million output tokens. While Opus 5 shows modest performance gains over Opus 4.8 and competes closely with models like Fable on coding tasks, it was deliberately trained with less emphasis on cybersecurity exploitation. The company faces increasing competition from open-weight models like Kimi K3 and the rise of model routing systems that optimize costs for users.
