DeepSeek V4 Pro 0813 rolls out, updating flagship model in API
DeepSeek quietly updated its flagship V4 Pro model to version 0813, as shown in the official API documentation. The change keeps the model name (deepseek-v4-pro) but delivers the newest Mixture‑of‑Experts engine and a 1 M‑token context window, so existing integrations get a performance boost without code changes.
