Hey, yes, Claude 4 Sonnet and Claude 4 Opus are available with a Pro subscription. Claude 4 Sonnet can be used in normal mode, while Claude 4 Opus works only in Max mode. In this mode, you can still use your fast requests from your subscription, and pricing is calculated based on tokens.
It’s important to note that both Claude 4 models are not yet part of the slow request pool. This means that after exhausting the monthly limit of 500 fast requests, further use of these models is only possible with usage-based pricing enabled.
