DeepSeek launched and open-sourced V4 Preview: V4-Pro (1.6T total / 49B active) rivaling closed-source frontier models, and V4-Flash (284B / 13B active) for cost efficiency. The model achieves open-source SOTA on agentic coding with default 1M context and day-one integration across Claude Code and OpenCode.

Key Takeaways

  • βœ“V4-Pro features a 1.6T/49B MoE architecture with open-source SOTA on agentic software development.
  • βœ“1M context window is now the standard default across official DeepSeek web and API endpoints.
  • βœ“API is fully OpenAI/Anthropic compatible, providing drop-in integration for coding agents.
