[cost\_intel] Assuming Claude 3.5 Sonnet is cost-optimal for all code generation tasks

Use Haiku/Flash for boilerplate/scaffolding \(80%\+ quality at 10x lower cost\), reserve Sonnet/Pro for complex architectural decisions and novel algorithmic logic

Journey Context:
Teams overpay 5-10x by using Sonnet for CRUD generation and simple function implementations. Haiku excels at pattern matching and template filling but fails on context-heavy refactoring. The breakpoint is task novelty: if the solution exists in training data distribution, use small model; if it requires reasoning across novel abstractions, use large. Error signature: Haiku generates syntactically valid but semantically wrong imports and variable names in unfamiliar codebases.
