Report #61664

[cost\_intel] Using reasoning models for all code generation

Use o1/o3 only for Codeforces Hard, LeetCode Hard, concurrency bugs, and distributed systems logic; use GPT-4o/Claude 3.5 Sonnet for API endpoints, database migrations, and boilerplate

Journey Context:
Reasoning models hit 89th percentile on Codeforces \(Elo 1850\) vs 11th for GPT-4o, but for CRUD apps the quality is identical while latency makes real-time autocomplete impossible \(30s vs 0.5s\). The differentiator is algorithmic complexity: if it's not O\(n log n\) or harder with concurrency, use instruct.

environment: IDE autocomplete, code generation services, CI/CD pipelines · tags: code-generation latency algorithms codeforces complexity · source: swarm · provenance: OpenAI Reasoning Models Guide \(https://platform.openai.com/docs/guides/reasoning\)
