DeepSeek introduced V4 Preview as an open source release with a 1M token context window, setting a new standard for long context efficiency. The lineup includes DeepSeek V4 Pro, a high performance model with 1.6 trillion total parameters, and V4 Flash, a smaller and faster model designed for cost efficient use.
Both models deliver strong reasoning, coding, and agent capabilities, with V4 Pro competing with leading closed source systems. The release also features structural innovations like sparse attention and token compression, reducing compute costs while maintaining performance.
APIs are updated, and models are available for direct use and integration.
