Report #42083

[cost\_intel] Blind application of reasoning models to code translation/porting

Use instruct models for same-paradigm translation \(Python 2→3, JS→TS\); reserve reasoning models for cross-paradigm shifts \(imperative→functional, sync→async architecture\).

Journey Context:
Code translation has two complexity tiers. Syntactic translation \(Python to Ruby\) is pattern matching where GPT-4o excels. Semantic translation \(callback hell to async/await\) requires architectural reasoning where o1 shines. Using o1 for syntax is 20x overkill; using GPT-4o for architecture yields broken abstractions.
