[cost\_intel] Using GPT-4o for security vulnerability detection in C\+\+, Rust, or complex taint analysis

Use o3-mini or o1 for static analysis of memory safety, concurrency bugs, and complex taint flows; use 4o only for linting and style checks

Journey Context:
Reasoning models simulate symbolic execution, tracing taint flows across 5\+ hops \(user input -> parser -> transformation -> sink\) with 70% recall vs 20% for instruct models. They identify TOCTOU races and UAF patterns that require 'thinking' about execution order. Instruct models spot SQLi in obvious concatenations but miss 'parse-then-decode' vulnerabilities.
