DeepMind’s RAG System with Animesh Chatterji and Ivan Solovyev

Retrieval-augmented generation, or RAG, has become a foundational approach to building production AI systems. However, deploying RAG in practice can be complex and costly. Developers typically have to manage vector databases, chunking strategies, embedding models, and indexing infrastructure. Designing effective RAG systems is also a moving target, as techniques and best practices evolve in step with rapidly advancing language models. Google DeepMind recently released the File Search Tool, a fully managed RAG system built directly into the Gemini API. File Search abstracts away the retrieval pipeline, allowing developers to upload documents, code, and other text data, automatically generate embeddings, and query their knowledge base. We wanted to understand how the DeepMind team designed a general-purpose RAG system that maintains high retrieval quality. Animesh Chatterji is a Software Engineer at Google DeepMind and Ivan Solovyev is a Product Manager at DeepMind, and they worked on File Search Tool. They joined the podcast with Sean Falconer to discuss the evolution of RAG, why simplicity and pricing transparency matter, how embedding models have improved retrieval quality, the tradeoffs between configurability and ease of use, and what’s next for multimodal retrieval across text, images, and beyond. Sean’s been an academic, startup founder, and Googler. He has published works covering a wide range of topics from AI to quantum computing. Currently, Sean is an AI Entrepreneur in Residence at Confluent where he works on AI strategy and thought leadership. You can connect with Sean on LinkedIn.

Reinventing the Python Notebook with Akshay Agrawal

Interactive notebooks were popularized by the Jupyter project and have since become a core tool for data science, research, and data exploration. However, traditional, imperative notebooks often break down as projects grow more complex. Hidden state, non-reproducible execution, poor version control ergonomics, and difficulty reusing notebook code in real software systems make it hard to move from exploration to production. At the same time, sharing results often requires collaborators to recreate entire environments, limiting interactivity and slowing feedback. Marimo is an open-source, next-generation Python notebook designed to address these problems directly. Akshay Agrawal is the creator of Marimo and he previously worked at Google Brain. He joins the show with Kevin Ball to discuss the limitations of traditional notebooks, the design of reactive notebooks in Python, how marimo bridges research and production, and where notebooks fit in an increasingly agentic, AI-assisted development world. Kevin Ball or KBall, is the vice president of engineering at Mento and an independent coach for engineers and engineering leaders. He co-founded and served as CTO for two companies, founded the San Diego JavaScript meetup, and organizes the AI inaction discussion group through Latent Space.

Organizational Context for AI Coding Agents with Dennis Pilarinos

AI agents have taken on a growing share of software development work, so much so that the hardest problems are shifting away from code generation towards something new, context. The challenge is now contextualizing why systems work the way they do, how architectural decisions were made, and the sources of truth that exist outside of the code base. As teams adopt agentic tools, gaps or inconsistencies in context have emerged as a primary reason why software fails to meet production standards. Unblocked is a startup focused on solving this context gap. Their context engine aggregates and reasons over organizational knowledge spread across source code, pull requests, documentation, chat systems, and production telemetry. By acting as a context engine for both developers and AI agents, Unblocked aims to improve AI code quality and review, reduce interruptions, accelerate onboarding, and enable safer, more effective agentic workflows. Dennis Pilarinos is the Founder and CEO of Unblocked. Previously, he helped build Azure at Microsoft, worked at AWS, and co-founded BuddyBuild, which is a mobile CI platform acquired by Apple. Dennis joins Kevin Ball to discuss context engineering, reconciling conflicting sources nof truth, permission to wear AI systems, the shifting bottlenecks in the software development lifecycle, and what it means to be a software engineer in an increasingly agentic world.

SED News: OpenClaw Goes Viral, Mistral’s Compute Play, and the Agent Arms Race

SED News is a monthly podcast from Software Engineering Daily where hosts Gregor Vand and Sean Falconer unpack the biggest stories shaping software engineering, Silicon Valley, and the broader tech industry. In this episode, they cover the viral rise of OpenClaw and its founder’s move to OpenAI, OpenAI’s exploration of ads inside ChatGPT, and Alibaba’s push into agent-powered commerce during Lunar New Year. They also discuss Mistral’s acquisition of Koyeb to deepen its compute stack, the growing competition between ChatGPT, Claude, and Gemini, and what these moves signal about monetization, infrastructure, and control in the AI arms race. Gregor and Sean then dive deep into the rapid acceleration of agentic engineering. They examine how tools like Claude Code and Codex are compressing the idea-to-production cycle, what multi-agent orchestration means for software teams, whether the era of the “10x engineer” is ending, and how organizational structures may need to evolve as coding shifts from manual craft to supervised automation. Finally, they highlight standout threads from Hacker News, including reverse engineering a 1990 DOS classic, a 3D reimagining of flight tracking data, old-school practical film effects using cloud tanks, and the privacy-focused GrapheneOS mobile operating system. Gregor Vand is a security-focused technologist, having previously been a CTO across cybersecurity, cyber insurance and general software engineering companies.

Amazon’s IDE for Spec-Driven Development with David Yanacek

AI-assisted coding tools have made it easier than ever to spin up prototypes, but turning those prototypes into reliable, production-grade systems remains a major challenge. Large language models are non-deterministic, prone to drift, and often lose track of intent over long development sessions. Kiro is an AI-powered IDE that’s built around a spec-driven development workflow. It’s focused on helping developers capture intent up front, translate it into concrete requirements and designs, and systematically validate implementations through tasks, testing, and guardrails. It aims to preserve the creativity of AI-assisted development while producing software that is ready for real-world use. David Yanacek is a Senior Principal Engineer and a lead advisor on the Agentic AI team at AWS. Today, his work focuses on Kiro, frontier agents, Amazon Bedrock AgentCore, and AWS’s operational agents. He joins the show with Kevin Ball to discuss the design of Kiro, how spec-driven development changes the way teams work with AI coding agents, and what the next generation of agentic software development might look like.
