DeepSeek is quietly rolling out V4-Pro-0813 on the API right now

Ran this a few minutes ago (Aug 12, 15:40 UTC). The deepseek-v4-pro endpoint is now returning system_fingerprint: fp_v4pro_20260812_... — a build stamped │ today — while deepseek-v4-flash still returns its stable July 31 fingerprint. The official pricing docs already list the model version as │ DeepSeek-V4-Pro-0813, but the changelog, homepage and HF weights haven't been updated yet.
