Anthropic has just released Claude Sonnet 4.5, and it’s a big step towards AI that doesn’t just answer questions – it gets real work done. The model can now run tasks continuously for over 30 hours without losing the thread, which is a huge leap for businesses looking to automate complex workflows.
Why this matters
Until now, most AI models were great at short bursts of help – think answering questions, generating text, or writing snippets of code. But real business tasks are rarely one-and-done. They involve research, planning, multi-step execution, and often juggling multiple tools at once. That’s where Sonnet 4.5 changes the game.
In a demo, the model built a fully functional chat application – 11,000 lines of code – working autonomously over days. That’s closer to the type of digital teammate companies have been waiting for.
What companies can do with Sonnet 4.5
- Software Development at Scale
- Automate boilerplate coding, integrations, and debugging.
- Use Sonnet as a junior developer that never tires, freeing your team for higher-level design and problem-solving.
- Research & Analysis
- Run deep market research that requires pulling information from multiple sources.
- Produce structured outputs like spreadsheets, reports, or competitor comparisons without constant prompting.
- Operations & Admin
- Schedule meetings by cross-checking calendars.
- Read dashboards, generate summaries, and draft status updates.
- Keep track of tasks across tools like Slack, Teams, Notion, or your CRM.
- Customer-Facing Support
- Build custom agents that can troubleshoot issues, navigate your knowledge base, and even take action in customer systems.
- Scale up service without scaling headcount.
- Specialist Domains (Finance, Cybersecurity, Science)
- Handle long-context, detail-heavy work such as scanning security logs, modelling financial scenarios, or digesting long technical papers.
Why now
Every week, AI providers are rolling out new features but Sonnet 4.5 shows that extended autonomy and reliable tool use are finally here. The building blocks Anthropic is shipping (virtual machines, memory, multi-agent orchestration) give companies the chance to build their own advanced AI systems rather than relying on generic assistants.
The bottom line
Claude Sonnet 4.5 marks a turning point: from AI as a chatbot to AI as a dependable digital co-worker. The companies who start experimenting now will be the ones who gain the biggest efficiency and innovation edge.
At Dragon AI, we can help you integrate Sonnet 4.5 into your workflows – whether that’s coding support, research automation, or building custom agents for your teams.
