Claude Opus 4.7

Claude Opus 4.7 is a version of Claude, the AI model made by Anthropic. Claude is an AI that converses with people in writing, answers questions, and writes text or code, and it comes in a few different tiers. Opus is the name of the line focused on handling complex, difficult tasks, and the number 4.7 refers to a specific revision within that line.

To put it another way, the Claude brand has several lineups, Opus is one of those lines, and 4.7 is the model number attached to it. The name alone doesn't tell you exactly what has changed, so you'd need to check the information Anthropic releases to find out what's actually different.
