It hasn’t been a good few days for Pro subscribers to Claude. First, we saw evidence that Anthropic was moving to remove Claude Code from the Pro tier, which didn’t affect current subscribers, but meant that some new subscribers weren’t allowed to use it. Now, an update to Anthropic’s documentation gives us another insight into what the company wants to achieve with the Pro tier, and it’s even more bad news. As per the documents, it seems that Anthropic is locking Claude Pro subscribers out of its powerful Opus models…unless they pay extra, of course.
