Hi! There is a major naming confusion here.

While fixing this, please rename the existing “Deepseek V3.1” to its correct name, “DeepSeek V3 0324”, this model was released on March 2024, and it has been incorrectly referred to as “V3.1“.

Also could you add the real “DeepSeek V3.1” (released in Aug 2025 with 128K tokens) to the model selction?
