Anthropic's Opus 5 is about token efficiency, not a capability leap
Models are improving quickly, but the cheaper options are often good enough.

Today, Anthropic rolled out Opus 5, the newest update for the model that has recently become a popular choice for coding and other software development tasks, among other things.
While this is a noteworthy bump for Opus, it doesn't seem to be an Opus 4.5-level breakthrough in agentic coding performance.
