Quick Summary

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

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

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

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.

LangSmith LLM Gateway lets you enforce spend limits and redacts PII before requests reach the model.

Not after the fact. https://t.co/8ApmVf0u5g

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.
