Claude Opus 4.5: Cheaper AI, Infinite Chats, Human-Beating Coding

What if an AI could outperform every human applicant for a top engineering job? Anthropic's new Claude Opus 4.5 model does just that, offering state-of-the-art AI power. Scoring higher than any human candidate on Anthropic's toughest engineering exam, the model also sets a new record on a key coding benchmark (80.9%) while slashing costs by nearly two-thirds. Its breakthrough efficiency allows it to match or exceed previous models' performance using up to 76% fewer tokens, making it faster and more accessible for everyone. This leap in performance and accessibility signals a major shift in how AI will reshape complex professional jobs, intensifying the race between tech giants. Practical uses already include autonomous code migration, self-improving agents that refine office tasks, and even "infinite chats" that never lose context.
