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.
Entire contract libraries load into one 200K context call, extracting obligations, payment terms, and renewal dates from hundreds of documents at once.
Code generation paired with nuanced reasoning flags edge cases and memory leaks linters miss, returning test cases and refactor suggestions in one prompt chain.
