Claude AI models compared: prices run from $4 down to $0.10

A new comparison of Claude, the AI assistant from Anthropic, puts three price points side by side: $4 for Opus, $2 for Sonnet 5.5 and $0.10 for Haiku. The gap between the top and bottom is large. For a business that pays for AI tools, the model it picks could move the monthly bill a lot.

What the comparison shows

Claude comes in three different models. According to the comparison, Opus is listed at $4, Sonnet 5.5 at $2 and Haiku at $0.10. That makes Opus twice the listed price of Sonnet 5.5, and Haiku far cheaper than both.

What is not known yet

The material does not say what the prices cover. The unit is not stated. It could be a price per use, per amount of text or per month, but that is not confirmed. The material also does not explain what each model does best, how they differ in quality, or when the prices were set.

• What each price actually measures
• How the models differ in ability
• Whether the prices apply to all kinds of use

Who it affects

Business owners who pay for AI tools or are thinking about starting are the most affected. Everyday users may care too, since the same models can sit behind the apps they use. The cheapest option is not automatically the best fit, and the most expensive is not automatically needed.

What to do

Before comparing the three numbers, check what each one covers on Anthropic's own pricing information. Then compare like with like.
