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. AI Gateway will route to providers with the new weights:
import { streamText } from 'ai';
const result = streamText({ model: 'deepseek/deepseek-v4-pro-0831', prompt: 'Fix the failing tests in this repo and open a PR.',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.
AI Gateway reflects provider pricing with no markup and does not charge a platform fee on inference, including on Bring Your Own Key (BYOK) requests. Learn more about AI Gateway, view the AI Gateway model leaderboard or try it in our model playground.
