Arca 如何用 AI 智能体处理跨天金融工作
Using Agents for Long-Horizon Financial Work — Aman Singh, Arca
Arca 正在构建 AI 原生财富管理公司，其 AI 负责人 Aman Singh 在 AI Engineer New York 介绍了支撑该业务的架构：自研 harness 与持久记忆，让智能体工作流可以跨越数天而非数小时。系统在涉及 10 万美元税单等场景时引入人工审批，并默认内置合规与可审计性、安全护栏和提示词注入防御。Arca 选择自建智能体基础设施，交易执行仍由人类专家负责。
Arca head of AI Aman Singh joins Latent Space head of editorial Richard MacManus at AI Engineer New York, to discuss how Arca is building an AI-native wealth management firm.
Singh explains Arca's architecture, which includes a custom harness and persistent memory. He also digs into how Arca runs agentic workflows that span days, not hours.
