If anything, Anthropic has the product lineup that makes the most sense. Higher numbers mean better model. Haiku < Sonnet < Opus which translates to length/size. Free < Pro < Max. Contrast to something like OpenAI. They've got gpt4.1, 4o, and o4. Which of these are newer than one another? How do people remember which of o4 and 4o are which?
