Testing 1.6T Param DeepSeek V4 Pro: Average Coding, Outpriced by GPT-5.6
curiousily_ · reddit · 2026-08-13
A developer tested the newly released DeepSeek V4 Pro (0813) via OpenRouter. In OpenCode and agentic workflows, the model's performance was underwhelming, especially compared to the V4 Flash version. While inference speed is decent (65 tok/s), its API pricing is no longer highly competitive (compared to GPT-5.6 Luna).
