Silicon Valley has spent much of the past week on red alert, digesting the arrival of Moonshot AI's Kimi K3, a Chinese AI model that can allegedly beat some of the best systems built by US companies at a fraction of the cost. Its performance alone would have been enough to intensify the rivalry between […]

Traditional RAG hits a ceiling on analytical tasks that span hundreds of documents. This post shows how to use task-aware knowledge compression (TAKC) on AWS to pre-compress entire knowledge bases into task-specific representations, cache them at multiple fidelity tiers, and route each query to the right tier, with an open-source implementation you can deploy.
In this post, we cover why Deepgram built on IAM temporary delegation, how the integration works end-to-end, and what it unlocks for customers running Deepgram speech models on SageMaker AI. With this integration, Deepgram has reduced the time for initial investigation on a SageMaker AI support ticket from days to minutes.

## 文档签名的“Let's Encrypt”来了：免费、开源、自托管 在数字签名领域，Adobe 的 Approved Trust List（AATL）和 DocuSign 等商业服务长期占据主导地位，用户往往需要为每份文档支付费用，且验证流程受限于特定商业生态。现在，一个名为 **Let's Seal** 的开源项目试图打破这一格局，其口号是“做文档证明领域的 Let's Encrypt”——让文档签名像 HTTPS 证书一样免费、开放、可自托管。 ### 核心标准：SEAL Let's Seal 的核心是 **SEAL（Sealed Evidence Anchored to a Ledger）** 标准，它定义了一种证明文件真实性的方法：一份文件被密封后，任何人都可以使用任意符合标准的工具验证其完整性、签发时间和签发者身份。项目提供了参考实现、免费网络服务以及自托管方案，所有组件均开源（Apache-2.0 许可证）。 ### 三种使用方式，全部免费 1. **Web 应用**：访问 app.letsseal.org 即可在浏览器中免费密封文件，支持远程或当面签名请求，甚至无需电子邮件即可完成签署。 2. **命令行与 API**：`sealbot` 终端工具、REST API 和 SDK 允许开发者将密封功能集成到自有系统中。 3. **自托管**：用户可以运行完整的密封引擎，使用自己的证书颁发机构（CA）签发密封，完全掌控数据。 验证功能始终免费且无需账户，可通过 verify.letsseal.org 或离线工具完成。 ### 密封证明的三重保证 一份 SEAL 证明从三个维度提供加密保证： - **完整性**：文件自密封后未被修改一个字节，任何改动都会导致签名失效。 - **时间锚定**：通过 **OpenTimestamps** 将时间戳锚定到比特币区块链，无需信任 Let's Seal 自身。 - **签发者身份**：由特定证书签发，若组织已证明域名控制权，密封将携带该域名作为可机器验证的身份标识。 此外，每次密封都会被写入一个公开、仅可追加的透明度日志（遵循 RFC 6962），其根哈希同样锚定到比特币区块链，使得密封记录的本身也可防篡改，任何人都可审计。 ### 行业意义与挑战 Let's Seal 的理念与 Let's Encrypt 如出一辙：将数字签名从“付费服务”转变为“公共基础设施”。在 AI 生成内容泛滥、文档伪造风险上升的当下，免费且可验证的签名方案具有重要价值。然而，要挑战 Adobe 的 AATL 生态和 DocuSign 的便利性，Let's Seal 仍需解决用户习惯、商业集成和证书信任链的普及问题。目前，其自托管模式更适合对成本和数据主权敏感的企业与开发者，而普通用户可能更依赖其免费 Web 服务。 无论如何，Let's Seal 为文档真实性认证带来了一个真正的开源替代方案，其“永久免费、无每文档费用”的承诺，可能成为推动行业变革的起点。
