Anthropic Launches Claude Opus 5 with Frontier-Class Intelligence at Half the Price of Fable 5

My take: On July 24, Anthropic launched Claude Opus 5 with three changes that directly affect the decision of which tool to use: a one-million-token context window, an adjustable effort control (low, medium, and high) to manage cost versus capability, and pricing identical to Opus 4.8, meaning $5 and $25 per million input and output tokens respectively, half of what Fable 5 charges.

On SWE-bench Verified, an external and widely accepted benchmark for measuring real programming task resolution, Opus 5 reaches 96%. That is a number hard to ignore for any team or freelancer using AI for code. For those paying for Fable 5 today, the practical question is whether Opus 5 delivers the same results at half the cost.

What AI tool are you using for coding or content creation, and when did you last check whether it still gives you the best return on what you pay?
