“It’s intelligent, efficient, and the best model in the world for coding, agents, and computer use.”
“Opus 4.5 is a step forward in what AI systems can do, and a preview of larger changes to how work gets done.”
“Pricing is now $5/$25 per million tokens—making Opus-level capabilities accessible to even more users, teams, and enterprises.”
“Testers noted that Claude Opus 4.5 handles ambiguity and reasons about tradeoffs without hand-holding.”
“Early testing shows it surpasses internal coding benchmarks while cutting token usage in half , and is especially well-suited for tasks like code migration and code refactoring.”
