Key Points

  • LangChain – Introduces Managed Deep Agents that retain the familiar project layout (AGENTS.md, skills/, subagents/, tools.json) and adds a Context Hub for persisting and updating agent context across sessions; a technical roundtable on June 17 in Munich will cover production‑grade agents, agent harnesses, and the Deep Agents SDK.
  • MiniMax – Launches MiniMax M3, an open‑weights model that merges a 1 million‑token context window, frontier coding, agentic abilities, and native multimodal (image/video) support, with benchmark scores highlighted and a 50 % discount for the first week; the model appears automatically in the Hermes Agent picker and credits the Teknium and Nous teams.
  • OpenRouter – Announces that MiniMax‑M3 is now available on its platform, offering the same 1 M‑token context, frontier coding, agentic performance, and multimodal capabilities.
  • Visual Studio Code – Promotes its new VS Code Learn Series episode “Extending Agents,” which teaches how to use tools, agent plugins, and third‑party agents within the editor.

LangChain (@LangChain)

Managed Deep Agents keeps the project shape you already know: ↳ AGENTS.md, skills/, subagents/, + tools.json

Context Hub gives your agent a managed place to retain and update this context across sessions, allowing agent definition to evolve over time. https://t.co/jx3E0Sn2XH

On June 17th, join LangChain’s Steffen Hausmann in Munich for a technical roundtable on production-grade agents, agent harnesses, and the open-source Deep Agents SDK.

OpenRouter now supports "apply_patch," a server tool that lets models propose file edits using V4A diffs through the Responses API. The model generates a patch, and OpenRouter validates the diff syntax server-side. This feature allows for more efficient and accurate file editing. xAI has released grok-build-0.1 in public beta via the xAI API. This model powers the Grok Build CLI and excels at agentic coding, priced at $1/m input and $2/m output. Google AI has released an episode of Release Notes featuring the architects of Gemini, including @JeffDean, @koraykv, @OriolVinyalsML, and @NoamShazeer. They discuss their journey and the people behind the model. LangChain has released LangSmith LLM Gateway, which enforces spend limits and redacts PII before requests reach the model. They also announced Deep Agents v0.6, which makes harness profiles a first-class abstraction, allowing for production-grade performance at lower costs. NVIDIA has announced a new era of PC, but the details are unclear. OpenAI has launched Rosalind Biodefense to help trusted builders develop new biodefense and pandemic preparedness capabilities. They are also expanding trusted access to GPT-Rosalind for select U.S. government and allied partners.
