So it’s 1/3 the price of Opus 4.1…

…and potentially uses a lot less tokens?
Excited to stress test this in Claude Code, looks like a great model on paper!

For anyone else confused, it's input/output tokens
$5 for 1million tokens in $25 for 1million tokens out

This is the biggest news of the announcement. Prior Opus models were strong, but the cost was a big limiter of usage. This price point still makes it a "premium" option, but isn't prohibitive.
Also increasingly it's becoming important to look at token usage rather than just token cost. They say Opus 4.5 (with high reasoning) used 50% fewer tokens than Sonnet 4.5. So you get a higher score on SWE-bench verified, you pay more per token, but you use fewer tokens and overall pay less!
