Vellum is a personal AI assistant that you own and customize. It runs locally on your machine or in Vellum Cloud, remembers your context over time, connects to your tools and takes real actions like email, calendar, research and file work, with model choice across OpenAI, Anthropic, Gemini or local open weights via Ollama.
面向生产级 AI 的智能体可观测性、评估与持续改进平台
基于 OpenTelemetry 之上的 OpenInference 规范，采集智能体与 LLM 调用的 span、trace 和会话，埋点可跨工具复用。
在 span、trace 与会话三个层级运行评估，对海量生产数据衡量检索质量、工具调用与最终回答的优劣。
内置于产品中的智能体，可检查链路、推断根因，并给出供工程师上线前审阅的修复建议。
当需要让轨迹数据留在自有基础设施内时，可自行部署这一领先的开源追踪与评估工具。

A custom-built memory system that retains you, your people, preferences and work across every conversation, rather than resetting each session.
Connect Google Workspace, Slack, Notion, your filesystem and community plugins so the assistant can send emails, manage calendars, browse, create slides and run research.
Set permissions so sensitive actions like emailing new contacts or modifying key files require approval until you mark them trusted.
Switch between OpenAI, Anthropic, Gemini or open-weight models via Ollama at any time, keeping you free of a single vendor lock-in.
