Both GPT 5.6 Luna and Nova Micro are capable AI models. The best choice depends on your specific use case: consider pricing, context window, speed, and which capabilities (vision, reasoning, audio) you need.
Nova Micro has a lower blended cost. GPT 5.6 Luna: $1.00 input / $6.00 output. Nova Micro: $0.04 input / $0.14 output.
GPT 5.6 Luna has a larger context window: GPT 5.6 Luna supports 1.1M tokens vs Nova Micro at 128K tokens.
GPT 5.6 Luna supports vision/image input, but Nova Micro does not.
Key differences: Nova Micro is significantly cheaper; only GPT 5.6 Luna supports vision input; only GPT 5.6 Luna offers extended reasoning mode. Compare full specs on this page.
If cost is your priority, choose the cheaper option. If you need the highest intelligence for complex tasks, pick the higher-scoring model. For long documents or codebases, choose the larger context window. You can try both GPT 5.6 Luna and Nova Micro for free on idapt.app to see which performs better for your specific needs.
