Claude Sonnet 5

Anthropic updated its mainstream model for coding, agent workflows and everyday knowledge work.

Sonnet 5 shows the other side of agentic progress: long-running workflows must not only be possible on a flagship but fast and affordable enough for routine use. The event therefore belongs on the autonomy line even though the model remains general-purpose rather than a standalone agent.
