Making LLM Agents Useful in Production
This curated newsletter edition surveys recent work showing how to move language-model agents from demos to production. Highlights include a Galileo field engineer who built a Claude Code-based system that queries 15 repositories to answer customer questions; OpenAI’s Codex team dogfooding their tooling; and Databricks’ analysis of orchestration and choreography patterns needed as agents scale. The edition also summarizes multiple technical papers and benchmarks (Video-MME-v2, Claw‑Eval, DataFlex), argues for focusing on the agent harness and runtime (Sebastian Raschka), and presents tools addressing agent memory and runtimes (mem0, goose in Rust). The newsletter covers architectural patterns (multi-source MCP), an approach called Recursive Language Models (RLMs) that reduces RAG reliance, and practical walkthroughs for using Claude Code as a personal operating system.
Advances in agent harnesses, memory, evaluation, and orchestration lower barriers to deploying LLM agents in production—relevant to marketing and support automation but not an industry-shifting platform announcement.

Key Takeaways & Evidence Grounding
- Al Chen, a field engineer at Galileo, built a Claude Code workflow that queries 15 internal repositories, Confluence docs, and deployment notes to answer customer questions, including a 16-line daily sync script authored by Claude Code.
- OpenAI’s Codex team publicly described dogfooding their own development tools in a candid interview with a Codex product lead and developer-experience lead.
- Databricks (Sandipan Bhaumik) warned that scaling agents requires distributed-system patterns (orchestrator and choreography) to avoid silent handoffs, stale state, and untraceable decisions.
- Multiple new research and tooling items were highlighted: Video-MME-v2 (video evaluation hierarchy), Claw‑Eval (trajectory-aware agent safety evaluation), DataFlex (trainer abstractions for data-centric techniques), mem0 (memory API claiming ~26% accuracy gain vs OpenAI Memory and ~90% lower token usage), and goose (Rust-native agent under the Agentic AI Foundation/Linux Foundation).
- Paul Iusztin promoted Recursive Language Models (RLMs) as an alternative to traditional RAG pipelines, reporting tests up to 10M tokens with GPT-5 and Qwen3-Coder.

MicroGPT, Agent Limits, and New LLM Research Roundup
This newsletter edition curates recent technical papers, tools, and talks across the LLM and agent research landscape. Highlights include Andrej Karpathy’s microGPT — a 243-line, dependency-free Python implementation of core GPT mechanics — and benchmark results showing Claude 4.5 Opus scoring 74.4% on a bug-fix SWE-bench but only 11.0% on FeatureBench, which measures end-to-end feature development. New research reframes delegation in multi-agent systems (distinguishing task handoff from authority transfer), introduces benchmarks that test video models’ physical reasoning, and proposes memory and control mechanisms (UMEM, GRU-Mem) that improve multi-turn learning and inference speed. Jeff Dean’s talk on the Pareto frontier in AI scaling and other educational resources (notably repositories and notebooks) are also highlighted.
AI Systems You Can Inspect: Research & Tools Roundup
A curated newsletter roundup (published 2026-05-09) highlights recent AI research, tooling, and demos that emphasize inspectability and robustness. Key items include UIUC’s AgentSPEX (a human-readable YAML agent spec achieving top benchmark scores), Allen AI’s MolmoAct2 robot foundation model running closed-loop at 12.7Hz on a sub-$6K arm, DeepMind’s Decoupled DiLoCo for failure-tolerant distributed training, and RationalRewards’ multi-dimensional critique model for image-generation rewards. The edition also covers Stripe’s internal Protodash prototyping studio, Microsoft Research’s “New Future of Work” findings on AI at work, the EvalEval coalition’s evaluation-cost analysis (a GAIA run costing $2,829), and several tooling releases (CLAUDE.md rules, RAG-Anything, graphify). The collection focuses on reproducible workflows, agent safety patterns, and infrastructure that reduces fragility in development and deployment.
RAG Systems and AI Agents for LLM Workflows
A developer journal detailing a week of work building Retrieval-Augmented Generation (RAG) systems and multi-phase AI agents that integrate LLMs with real data and tools. Implementations include an ArXiv RAG research assistant (ingest 30 recent papers, 300-word chunks, sentence-transformers embeddings, ChromaDB vector search, GPT-4o-mini for grounded answers) and a TaskAgent that orchestrates tool calling, phase management, and state persistence (examples: weather API, Caesar cipher decryption). The post describes engineering decisions (chunk size, semantic overlap), debugging (properly tagging tool results as role 'tool' to avoid repeated calls), operational challenges (token growth, tool failures, state persistence across restarts), and an MCP (Model Context Protocol) server to expose tools via REST as a standard protocol. Emphasis is on treating agent orchestration like distributed systems: caching tiers, transactions per turn, observability and testing practices.
