Both GPT 5.6 Luna and Hermes 3 70B 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.
Hermes 3 70B has a lower blended cost. GPT 5.6 Luna: $1.00 input / $6.00 output. Hermes 3 70B: $0.70 input / $0.70 output.
GPT 5.6 Luna has a larger context window: GPT 5.6 Luna supports 1.1M tokens vs Hermes 3 70B at 131K tokens.
GPT 5.6 Luna supports vision/image input, but Hermes 3 70B does not.
Key differences: 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 Hermes 3 70B for free on idapt.app to see which performs better for your specific needs.
