- Large software migrations and complex repository-scale engineering
- Difficult coding, debugging, implementation, and prototyping tasks
- Deep research and multi-stage professional analysis
- Enterprise workflows that can be delegated with relatively little supervision
- Complex document analysis involving charts, tables, diagrams, and PDFs
- Scientific and other difficult reasoning-intensive workloads
- Tasks where maximum model capability matters more than minimizing inference cost
