“Claude Opus 4.5 Is The Best Model Available” by Zvi

Claude Opus 4.5 is the best model currently available.

No model since GPT-4 has come close to the level of universal praise that I have seen for Claude Opus 4.5.

It is the most intelligent and capable, most aligned and thoughtful model. It is a joy.

There are some auxiliary deficits, and areas where other models have specialized, and even with the price cut Opus remains expensive, so it should not be your exclusive model. I do think it should absolutely be your daily driver.
