Scale is an enterprise AI company that supplies the data, evaluation and deployment layers behind production AI. Its Data Engine sources and labels training data for frontier models, its evaluation work benchmarks model capability, and its platform teams help enterprises and governments move AI systems from pilot into real operations.
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。

Its Data Engine sources and labels training data for frontier models, its evaluation work benchmarks model capability, and its platform teams help enterprises and governments move AI systems from pilot into real operations.
Human-sourced and expert-annotated training data, including specialist contributors with advanced degrees, at the quality bar frontier labs require.
Public leaderboards plus private benchmarks that test model capability and safety for the most ambitious AI developers.
Platform and services teams that pick the right use case, build the system and take ownership of the outcome.
Agentic systems designed around measurable business outcomes across private equity portfolios, energy and healthcare operations.
专项更强简化计算机视觉数据集标注与模型训练，但不太适合通用的 LLM 文本任务。
专注于企业级数据标注和训练数据整理，类似于 Scale 的核心标注业务。
提供企业级多模态标注和数据管理工具，但对托管式标注人力的强调较少。
专项更强在互联环境中跟踪、评估并交付 AI 模型与智能体。
免费 / 开源提供灵活的开源替代方案，适用于自定义数据标注和人机回环（Human-in-the-loop）标注管道。
专项更强构建、模拟、评估并监控可自我改进的 AI 智能体
专项更强Provides LLM evaluation and testing workflows, but lacks Scale's massive human-in-the-loop data labeling services.

高度专注提示词管理与版本控制，而 Arize 则优先考虑端到端追踪与机器学习可观测性。
通过 DeepEval 提供全面的大模型评估和单元测试，但缺乏 Arize 深入的生产监控基础设施。
