Google Launches Automated Review Feature in Gemini CLI Conductor
Google has enhanced its Gemini CLI extension, Conductor, by adding support for automated reviews. The company says this update allows Conductor “to go beyond just planning and execution into validation”, enabling it to check AI-generated code for quality and adherence to guidelines, strengthening confidence, safety, and control in AI-assisted development workflows.
Scaling Human Judgment: How Dropbox Uses LLMs to Improve Labeling for RAG Systems
To improve the relevance of responses produced by Dropbox Dash, Dropbox engineers began using LLMs to augment human labelling, which plays a crucial role in identifying the documents that should be used to generate the responses. Their approach offers useful insights for any system built on retrieval-augmented generation (RAG).
OpenAI Extends the Responses API to Serve as a Foundation for Autonomous Agents
OpenAI announced they are extending the Responses API to make it easier for developer to build agentic workflows, adding support for a shell tool, a built-in agent execution loop, a hosted container workspace, context compaction, and reusable agent skills.
