Anthropic’s Claude Sonnet 4.5, released September 2025, can sustain continuous autonomous work for over 30 hours on realistic engineering tasks — a massive leap from earlier models that managed just hours.
The Benchmarks That Matter:
- SWE-bench Verified: 77.2% — State-of-the-art for real-world software coding
- OSWorld: 61.4% — Real-world computer tasks, up from 42.2% just four months earlier
- 30+ hours — Sustained autonomous work on complex engineering tasks
Why This Matters for Enterprise:
Previous AI models required constant human supervision. Claude 4.5 can:
- Take a complex coding task and work through the night
- Handle multi-step workflows without losing context
- Navigate real computer interfaces autonomously
- Maintain quality over extended sessions
Strategic Implication:
Claude 4.5 is best for sustained reasoning, complex autonomous tasks, and compliance-heavy interactions where you need an AI that can think deeply and work independently.
