DeepSeek V4 wins on performance AND price. It scores higher on coding and math benchmarks while costing 89-96% less than GPT-4o. The only area where GPT-4o has a slight edge is general English knowledge (MMLU), but the difference is negligible for most applications.
For Chinese language tasks, DeepSeek V4 dominates with a 14-point advantage. For coding tasks, it's consistently 2-10 points ahead.
