Also the biggest models are not always the best depending on what you're doing. 4.6 Sonnet is a decent model that can handle most coding tasks, and even 4.5 Haiku is fine for simple, well-defined tasks.

Using 4.6 Opus for simple things is not only wasting tokens, it's also slower. Sonnet will get a lot of tasks done in half the time for less than half the money
