Claude Sonnet 4.5 is Anthropic's best model for agents that use computers
Anthropic released Claude Sonnet 4.5 as their strongest model for coding, long-running agents, and computer use. It can operate autonomously for 30+ hours on complex tasks, uses tools more reliably, and shows large gains on real software engineering benchmarks (SWE-bench Verified) — meaning agents can now realistically own multi-step back-office work rather than single-turn Q&A.
The threshold where an AI agent can reliably do a full ops workflow end-to-end (open the TMS, read the email, draft the reply, update the shipment) just moved much closer.
For forwarders and 3PLs, this is the model class that makes "an agent handles the routine spot quote from inbox → TMS → reply" go from demo to something worth piloting. Start listing the 3–5 repetitive workflows in your ops inbox that eat the most junior hours — those are the first candidates.
