OpenAI's AgentKit will be so insane, build every step of agents on one platform. These visual agent builders make the whole process of iterating and launching agents far more efficient. It sits on top of the Responses API and unifies the tools that were previously scattered across SDKs and custom orchestration. It lets developers create agent workflows visually, connect data sources securely, and measure performance automatically without coding every layer by hand. The core of AgentKit is the Agent Builder, a drag-and-drop canvas where each node represents an action, guardrail, or decision branch. Developers can link these nodes into multi-agent workflows, preview results instantly, and version each setup. It supports inline evaluation so that developers can see how changes affect output before deploying. The Connector Registry is a single admin panel that manages how data and tools connect across the OpenAI ecosystem. It centralizes integrations like Google Drive, SharePoint, Dropbox, and Microsoft Teams. Large organizations can govern access and flow of data between agents securely under one global console. ChatKit provides a ready-to-use chat interface for embedding agents inside apps or websites. It manages streaming, message threads, and model reasoning displays automatically. Developers can skin the interface to match their product without writing custom front-end code. Under the hood, all these blocks use the same execution core that runs agent reasoning through OpenAI’s APIs. Workflows in Agent Builder compile down to structured instructions for the Responses API, which handles model calls, tool use, and context passing. Connector Registry handles authentication and routing for external tools, while Evals and RFT provide feedback loops that improve agents over time. This integration means developers no longer need to handle orchestration logic, model evaluation pipelines, or safety layers separately. Everything runs natively within OpenAI’s control plane with managed security, automatic versioning, and built-in testing. In short, AgentKit standardizes the entire life cycle of an AI agent—from visual design to deployment and performance tuning—inside a single unified system.

Grok Build 开源了,开源 harness 时代终于要来了吗?! Claude Code 现在还是闭源, 反而显得有点被动了🤔。。。 不愧是Elon,真是一步妙手啊,只用了四天完成信任崩塌到重建,xAI这次用开源把隐私危机打成了生态先手,看来并不是草台班子😂 被爆全量上传代码仓库的隐私风波还没平息,SpaceXAI直接把整个Grok Build的agent harness全部开源出来, 这事我觉得有意思的地方是两它为什么是今天开,而不是上个月? 上个月 Grok Build 以 beta 上线,SuperGrok / X Premium+ 用户能用一个终端原生的 coding agent。 Plan Mode 先出计划让你审核,Subagents 并行拆任务,底层 Rust 写的,架构干净。 然后上周出了件事, 一个研究员做 wire-level 分析发现,Grok Build CLI 会把整个 git repo——包括历史、包括潜在的 secrets——打包上传到 Google Cloud bucket。隐私开关只管“是否用于训练”,不管传不传。 讲真这事对 coding agent 是致命的。 因为 coding agent 的 harness 对文件系统有近乎上帝视角的访问权。 你的 IP、商业逻辑、没公开的项目结构、不小心留在 git history 里的 key——它全看得见。 宣称“我们不看你数据”没用,用户要的是能自己验证“你没在看”。 时间线很紧凑: 7 月 11–14 日,争议发酵,研究员曝光上传行为。 Elon 表态删数据、服务端关闭上传。 7 月 15 日,开源公告 + 重置 limits + 默认关闭 retention + 删掉所有之前保留的 coding data + 提供 bug bounty。 所以这次其实不是一次计划好的例行开源。更像是被争议倒逼的快速应对。 但 xAI 做得聪明的地方是——它借这个机会做了一件事:把“harness(连接层)”和“model(大脑)”切开了。 Harness 开源,Apache 2.0,社区可以审计、fork、改掉上传逻辑、加 sandbox、接本地模型,Model 和 API 还是闭源的。 这个配置——闭源模型 + 开源 harness——正在变成 2026 年 agentic coding 的主流。 OpenAI 的 Codex CLI 走的同一条路,Anthropic 的 Claude Code 现在还是闭源,反而显得被动了。

The Visual Studio Code insiders version that just shipped and will ship in the next few days will come with an insane amount of new capabilities. A few highlights: - You can now run sub-agents in parallel. Yes, really. I even attached a video. - Major UX improvements for sub agents, especially visible in the chat window - A new search tool wrapped as a sub-agent that iteratively runs multiple search tools: semantic_search, file_search, grep_search Which connects nicely to the point above: multiple searches running in parallel, efficiently and fast - Anthropic’s Message API is now enabled by default - You can choose the model for the cloud agent (three available, all premium) - Extended thinking support when using the Claude cloud agent This is part of the broader multi-vendor cloud support under AgentsHQ I wrote about a few weeks ago - Tasks sent to the background agent (basically the CLI tool) now always run in isolation, each with its own git worktree - In a multi-repo workspace, assigning a task to a cloud agent prompts you to choose the target repo Same behavior when opening an empty workspace with no repo - Support for building an external index for files not supported by GitHub’s default indexing - UI/UX improvements for starting new sessions and switching between local / background / cloud agents - Skills are now first-class citizens, just like prompt files, with better UX indicating when a skill is loaded - Improved API for dynamic contribution of prompt files New V2 includes skills as part of the model. Curious to see the extensions that will leverage this - Finally, initial support for showing context usage percentage per session - Skills are enabled by default - Resizable chat window and session view. Small thing, but it was driving me crazy 😁 - A new integrated browser meant to replace the old simple browser Maybe the beginning of real browser use? - Better UI/UX for token streaming in chat - Ability to index external files not supported by GitHub There’s a lot more. Some of it hasn’t fully landed yet, but everything that has is already in Insiders. The next stable release should drop in early February. As usual, I’m just shocked by the volume of features this team ships every month. After the holiday slowdown, this one is shaping up to be a wild release.
