OpenAI introduces the GPT-5.6 three-tier model family: Sol for frontier coding and reasoning (scoring 91.9% on TerminalBench), Terra as the balanced daily driver, and Luna for ultra-fast, cost-effective high-volume tasks.
Act as a principal software engineer. Analyze the following full-stack architecture for performance bottlenecks, concurrency race conditions, and memory leaks. Provide refactored code with strict TypeScript types, unit tests, and asymptotic complexity analysis.
