DeepSeek-V4 Flash 0731 vs GPT-5.6 Luna on DeepSWE: Cost and Coding

За 30 секунд

Что произошло

DeepSeek-V4 Flash costs six times less than GPT-5.6 Luna on coding tasks but solves fewer problems alone. A cascade using DeepSeek first beats both models individually.

Почему это важно

Engineering teams evaluating cost-effective AI coding assistance should consider this when balancing accuracy requirements against budget constraints and task complexity.

На что обратить внимание

DeepSeek performs poorly on JavaScript and reasoning-heavy tasks. The cascade strategy requires a test suite to validate solutions before escalating to Luna.
