1. Deep Research & Analysis
For knowledge workers who need synthesis across hundreds of pages of documentation or scientific literature, specialized models with large context windows have replaced traditional web search. Tools combining live verification with semantic retrieval drastically cut initial research time.
2. Coding & Automation Workflows
Modern AI developer tooling no longer just provides autocomplete; autonomous coding agents can refactor multi-file repositories, diagnose errors in production containers, and run end-to-end testing suites autonomously.
