Key Points

  • 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.

OpenRouter now supports "apply_patch," a server tool that lets any model propose file edits using V4A diffs through the Responses API.

The model generates a patch (create, update, or delete a file). OpenRouter validates the diff syntax server-side. https://t.co/JxTa2fXSP9

xAI (@xai)

grok-build-0.1 is now available via the xAI API in public beta.

This is the same model that powers the Grok Build CLI and excels at agentic coding.

Priced at $1/m input and $2/m output, it’s extremely cost effective, intelligent, and fast. https://t.co/2ZtqWM2QLU

Google AI (@GoogleAI)

Hear the architects of Gemini reflect on their journey to continue pushing the frontier of AI, on this episode of Release Notes.

@JeffDean, @koraykv, @OriolVinyalsML, and @NoamShazeer sit down on camera together to share a behind-the-scenes look at the people behind the model, https://t.co/wO1mD8Wwmc

LangChain (@LangChain)

What if you thought about your agent architecture like a nervous system?

Great insight from @cogent_security Co-Founder & CTO Geng Sng on the Max Agency Podcast.

Deep Agents v0.6 makes harness profiles a first-class abstraction.

Now, you can get production-grade performance from models like @Kimi_Moonshot, @Alibaba_Qwen, and @DeepSeek_ai at 20x+ lower cost than closed frontier APIs.
