Anthropic Launches Claude Opus 5 AI Model for Affordable Workplace Tasks

My take: The launch of Claude Opus 5 confirms something many already suspected: competition between AI labs is driving down the price of access to frontier-level models. Opus 5 matches or beats Fable 5 on 8 of 13 benchmarks, at half the price, with input pricing of $5 per million tokens and output at $25 per million. For any organization or professional already on Opus 4.8, this is a direct upgrade at no additional cost.

It is worth reading the benchmarks with some scrutiny: the comparisons between Opus 5 and Fable 5 were run by Anthropic on their own models, which always creates the possibility that the test design favors the new product. The ARC-AGI-3 result, managed independently by the ARC Institute, is harder to question: Opus 5 scored 30.2%, three times better than the next model on the list.

What does feel conclusive is the pattern: week after week, the price of frontier AI keeps falling. If cost was the reason your team or business was not adopting more capable AI tools, does that argument still hold?
