Based on the Capability Index, DeepSeek V4 Pro scores higher (81.6 vs 60.8). However, "better" depends on your use case — pricing, speed, context window, and specific capability needs all matter.
GPT 4o Mini has a lower blended cost. GPT 4o Mini: $0.15 input / $0.60 output. DeepSeek V4 Pro: $0.43 input / $0.87 output.
DeepSeek V4 Pro has a larger context window: GPT 4o Mini supports 128K tokens vs DeepSeek V4 Pro at 1M tokens.
GPT 4o Mini supports vision/image input, but DeepSeek V4 Pro does not.
Key differences: DeepSeek V4 Pro has a notably higher capability index (20.8 point gap); GPT 4o Mini is significantly cheaper; only GPT 4o Mini supports vision input; only DeepSeek V4 Pro 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 4o Mini and DeepSeek V4 Pro for free on idapt.app to see which performs better for your specific needs.
