Introducing Claude Opus 5

Claude Opus 5 is a new AI model released by Anthropic that performs at a high level on benchmark tests while costing the same as the previous Opus 4.8 model. The model is notably proactive and can solve complex tasks like writing code to analyze images, and it has improved at finding cybersecurity vulnerabilities (weaknesses in systems) without being trained to exploit them, meaning it can identify security problems but not weaponize them into actual attacks.
