DeepSeek V4 Pro now runs on updated weights on AI Gateway. They are used by default when you call `deepseek/deepseek-v4-pro`

, so existing requests pick them up with no change to the model ID or your code.

To use the updated DeepSeek V4 Pro, set model to `deepseek/deepseek-v4-pro-0813`

in the [AI SDK](https://ai-sdk.dev/). AI Gateway will route to providers with the new weights:

To run V4 Pro in a coding agent, use `vercel ai-gateway coding-agents setup`

to connect your agents to AI Gateway, then select `deepseek/deepseek-v4-pro-0813`

in the agent's model configuration. See the [coding agents guide](https://vercel.com/docs/ai-gateway/coding-agents).

AI Gateway reflects provider pricing with no markup and does not charge a platform fee on inference, including on [Bring Your Own Key](https://vercel.com/docs/ai-gateway/authentication-and-byok/byok) (BYOK) requests.
