Step 5 PreviewAA榜单MoE架构开源大模型Agentic任务

阶跃发布旗舰模型Step 5 Preview,以600B参数量跻身AA榜单全球开源模型前三,10月15日开源,支持复杂开发任务与多模态输入。

Jieyu launches Step 5 Preview, a 600B-parameter model ranking top three in global open-source AI benchmarks, with open-source release on October 15.

Key points

  • 采用稀疏MoE架构,参数量600B但激活参数仅27B Uses sparse MoE architecture with 600B parameters and 27B active parameters
  • AA榜单综合智能指数得分44分,位列全球开源模型前三 Scores 44 on AA benchmark, ranking top three globally
  • 单任务成本仅为Claude Opus 5的1/8,性价比突出 1/8 cost of Claude Opus 5 per task, excellent cost-efficiency
  • 能自主完成ESP32开发板改造及连续3小时代码调试 Autonomously transforms ESP32 boards and debugs code for 3 hours
  • 在软件工程、金融等多领域基准测试表现均衡 Balanced performance across software engineering and finance benchmarks

Takeaway: Step 5 Preview以高参数量和低成本优势,推动开源大模型在复杂任务中的实际应用。 / Step 5 Preview's high parameter efficiency enables practical applications in complex tasks with lower costs.

Why it matters 展示开源大模型在工程实践中的突破,为AI工具性价比提供新标杆。
