DeepSeek Releases V4 Pro 0813 Model via API

DeepSeek released its new V4 Pro 0813 model, now accessible through API via OpenRouter. The model launched without a formal announcement on DeepSeek's website but is available for use. Based on previous releases (April's V4-Pro and July's V4-Flash), open weights are expected to be released. The model exhibits distinct visual differences across different reasoning levels (low, medium, and high), a behavior not observed in other models. Performance benchmarks were initially shared in private groups before appearing in public forums.
