Claude Opus 5 is Anthropic’s newest flagship model, offering major performance gains at the same price as Opus 4.8. It delivers state‑of‑the‑art results in coding, knowledge work, scientific research, and problem‑solving while also showing stronger alignment, safer behavior, and more consistent judgment.
