This is the first model that unifies frontier coding performance with broader reasoning capabilities — you're no longer choosing between a specialized code model and a general-purpose reasoning model. The numbers matter: 25% faster execution according to OpenAI, with midtask steerability that lets you redirect the model during long-running operations without losing context. That last part is crucial for anyone building agentic DevOps workflows — you can now col
