A comparative analysis of Kimi k3 and DeepSeek V4-Pro on October 15, 2026, revealed identical hit rates across nine tasks, but DeepSeek V4-Pro was approximately three times faster. However, this speed advantage reversed for coding tasks, where DeepSeek V4-Pro used significantly more tokens for reasoning. The study also highlighted that stricter output constraints, such as requesting only a number or a single word, resulted in a higher proportion of billed reasoning tokens compared to the visible output.
