Report #90628

[cost\_intel] SWE-bench shows o1 costs 50x more than GPT-4o but only improves 15% on simple bugs, creating negative ROI on easy tickets

Route to GPT-4o for bugs affecting <20 lines or single files; reserve o1 for architectural changes >200 lines or complex concurrency bugs

Journey Context:
On SWE-bench Verified, o1 solves 48% vs GPT-4o's 33% $15-point gap$. However, on 'easy' subset $single file, <20 line changes$, o1 achieves 55% vs 4o's 48% $7% gain$ at 50x cost $$50 vs $1 per task$. Break-even analysis: Use complexity heuristics $lines changed \+ file count \+ cyclomatic complexity$. Threshold: >0.7 complexity score justifies o1.
