Understanding ChatGPT Work

Simon Willison’s Weblog 1 month ago 42

OpenAI announced ChatGPT Work and the author of this piece documents how it works after iterating since July 9. ChatGPT Work is available only to subscribers paying at least $20/month (free and $8/month tiers do not have access). The article claims Work adds cloud execution with internet-capable code, a headless Chrome browser, persistent shared filesystem access across sessions, and capabilities like publishing ChatGPT Sites and running sub-agent sessions.

AI agents are making retrieval engineering a core engineering discipline

The New Stack 1 month ago 15

AI agents are shifting retrieval needs so that evidence delivery must be correct and timely for systems that investigate, reason, and act on users’ behalf. The article highlights that when retrieval is commoditized, competitive advantage shifts to decisioning, i.e., deciding what an agent should see and in what order before it acts. Engineers will therefore focus on end-to-end retrieval engineering workflows (hybrid retrieval, real-time signals, ranking, inference, and experimentation) rather than only embeddings or vector search.

Your AI agent is only as good as the harness around it

Agent demos can look reliable until real inputs trigger missing records, tool errors, policy changes, or capability limits that reveal the system is not production-ready. The article’s example billing trace includes a 13.4s run that used 2,180 tokens and cost $0.04, illustrating how a harness logs and gates work around the model. Production deployments change by treating the model as only one component and adding tool contracts, permissions, deliberate context, traces, and failure-focused tests so wrong calls are contained and diagnosable.
