Report #103339

[cost\_intel] Code generation is dominated by output-token cost, and cheap models need more retries

Budget for output tokens at a 2-5x multiple of input-token price, set tight max\_output\_tokens, and choose models by pass@1 correctness rather than per-token cost.

Journey Context:
Providers charge output tokens at a multiple of input tokens \(e.g., Anthropic charges 5x more for output than input across Claude models\). Code generation is output-heavy, often hundreds to thousands of tokens. A cheap model that costs 80% less per token but produces 50% more tokens and needs one retry to fix syntax errors can end up more expensive than a strong model that answers correctly first. The quality signature is pass@1 compilation/execution rate and the density of required edits. Measure cost-per-correct-line, not cost-per-call. Cheap models hold up for boilerplate and isolated functions; they fall off a cliff on cross-file changes, large refactors, and subtle API semantics.
