- Leverage “Computer Use”: Direct Claude to interact with UIs—click, type, navigate—more reliably than earlier versions.
- Hybrid Reasoning Architecture: Single model that toggles between fast replies and deep reasoning dynamically.
- Extended Thinking Transparency: Step-by-step logic is visible to users—users decide when depth is needed.
- Superior Coding & Agentic Workflows: Improved SWE-bench and TAU-bench scores, strong CLI and codebase handling.
- Large 200K Context Window: Ideal for extensive content, codebases, documents, or multi-step workflows.
- Multimodal & Vision Support: Understands charts, diagrams, visuals; extract and analyze data easily.
- Hybrid agility: Quick answers plus transparent reasoning.
- Developer-grade coding: Ideal for large codebases and CI workflows.
- Automation power: Computer interaction enables operational tasks.
- Huge context: Excellent for analyzing long docs or corpora.
- Multi-platform access: Via Claude UI, API, cloud tools, and data platforms.
- Extended thinking mode may slow down responses.
- UI‑based automation is still experimental and can misfire
- Deep thinking noticeably raises token usage and cost.
