DeepSeek团队正式推出并开源了DeepSeek-V4预览版模型,标志着高性价比的百万上下文长度时代到来。该系列包含两个模型:DeepSeek-V4-Pro拥有1.6万亿总参数和490亿活跃参数,性能媲美顶级闭源模型;DeepSeek-V4-Flash则拥有2840亿总参数和130亿活跃参数,主打快速、高效与经济。模型现已在官方平台通过专家模式和即时模式开放试用,API也已同步更新。完整的技术报告和模型权重已在Hugging Face平台发布,供社区研究和应用。
推荐理由
DeepSeek-V4 把 MoE 推到 1.6T 总参、49B 活跃,百万上下文 + 开源权重,这是开源阵营第一次在旗舰级闭源模型面前不落下风,做长上下文应用的团队该认真测一下了。
