Claude Opus 5: change AI with Unmatched Efficiency and Affordability

Anthropic shipped Claude Opus 5 on Friday, and the headline isn't the benchmark — it's the math. Half the price of Claude Fable 5, near-frontier intelligence, and available on Claude Max, Claude Pro's premium tier, and GitHub Copilot on day one. For teams running agents at scale, that's a real tailwind, not a marketing one.

Opus 5 doesn't just undercut Fable 5. It posts new state-of-the-art on the Frontier-Bench benchmark for software engineering and the GDPval-AA benchmark for knowledge work, and it does so at half the per-token cost. If you were holding off on routing real workloads through an LLM because the bill was ugly, the bill just got cut in half.
