Real-World Scenarios: When to Choose Which
The question that matters: “In what situation will I regret choosing A over B after 3 months?”
Advanced math steps through each operation in chain-of-thought, catching sign errors and boundary conditions. Manual proof validation drops from 6 hours per model release.
The 128K context pastes full infrastructure configs alongside logs and network traces for root cause analysis. Race conditions across 50+ microservices identified in under 90.
Function calling chains analysis, test generation, and PR submission in automated sequence. Hands-off migration from procedural to OOP patterns runs over weeks, not months.
