“Tara Seshan describes ChatGPT’s progression from chat to agents to persistent AI coworkers, with ChatGPT Work using Codex capabilities for knowledge-work tasks.”

#1 ▶️ AI’s third era: the rise of persistent AI coworkers | Tara Seshan (OpenAI’s product lead) Lennys Podcast Tara Seshan describes ChatGPT’s progression from chat to agents to persistent AI coworkers, with ChatGPT Work using Codex capabilities for knowledge-work tasks. OpenAI product teams build for model capabilities expected in two to three months; Tara Seshan says building for current models or for models expected a year ahead is “equally wrong.” ChatGPT Work and Codex use the same underlying capabilities; Work removes coding-oriented UI such as worktrees and exposes less technical detail, while Codex can perform the same tasks, including generating financial models and revenue predictions. Codex supports /visualize , which can turn a request such as “Visualize my ChatGPT usage until now” into a visualization using the user’s ChatGPT activity and charts.

“Peter Yang characterized Claude Cowork and ChatGPT Work as partial solutions, arguing that Grok Bot is the right end state for capable AI agents for non-technical users because it is easily understood as a computer running in the cloud.”

“Ian Silber uses ChatGPT Work, which runs in the cloud, and Codex to turn early ideas into prototypes or visual artifacts, including from a phone when he is away from a computer; he also uses AI to summarize Slack follow-ups and prepare context for meetings and recruiting.”

#5 ▶️ OpenAI’s Head of Design: This is the best time in history to be a designer | Ian Silber Lennys Podcast Ian Silber describes how OpenAI’s product-design team uses ChatGPT, Codex, and ChatGPT Work to prototype ideas, test durable interface decisions, and ship experimental product changes quickly. Ian Silber said engineers have sometimes increased productivity by 10x to 100x with AI, while design work still requires repeated feedback loops, including trying ideas, discarding them, and gathering user or internal feedback. For some ChatGPT features, OpenAI tries about 100 options, discards 99, and ships one; for other work, teams use a “building in public” approach, take large swings, and learn from rapid feedback. Ian Silber uses ChatGPT Work, which runs in the cloud, and Codex to turn early ideas into prototypes or visual artifacts, including from a phone when he is away from a computer; he also uses AI to summarize Slack follow-ups and prepare context for meetings and recruiting.

“On August 4, 2026 OpenAI launched three education plugins for ChatGPT Work and Codex—K–12 Educator, College Educator, and College Student—available through ChatGPT Edu and ChatGPT for Teachers, which connect to documents, calendars and approved apps to help teachers design differentiated lessons, syllabi, assessments and help students create personalized study guides, quizzes, flashcards and visual explanations.”

#2 📝 OpenAI News New ways to learn and teach with ChatGPT Work and Codex - On August 4, 2026 OpenAI launched three education plugins for ChatGPT Work and Codex—K–12 Educator, College Educator, and College Student—available through ChatGPT Edu and ChatGPT for Teachers, which connect to documents, calendars and approved apps to help teachers design differentiated lessons, syllabi, assessments and help students create personalized study guides, quizzes, flashcards and visual explanations. OpenAI says ChatGPT Edu (introduced 2024) and ChatGPT for Teachers (introduced 2025 and free for verified U.S. K–12 educators) provide institution-managed privacy and controls, the K–12 plugin integrates with Learning Commons, and OpenAI is the founding partner in the National Academy for AI Instruction aiming to equip 400,000 K–12 educators.

“How I AI Podcast Nick Baumann uses ChatGPT Work voice to delegate browser-based travel and expense tasks, ChatGPT Sites to build and privately share a searchable website, and a custom UGC Video plugin to turn raw clips into edited vertical videos.”

#9 ▶️ How this OpenAI engineer uses Codex + ChatGPT Work to automate everything How I AI Podcast Nick Baumann uses ChatGPT Work voice to delegate browser-based travel and expense tasks, ChatGPT Sites to build and privately share a searchable website, and a custom UGC Video plugin to turn raw clips into edited vertical videos. Using a hotkey-triggered voice orb that can read the current screen via an appshot, ChatGPT Work checked a Slack offsite message, checked calendar availability through plugins, created a travel task for SFO-to-Paris flights and a policy-compliant hotel in Navon, and created a separate task to find an Amazon microphone receipt and stage—without submitting—an expense report. ChatGPT Sites supports a SQL database, S3 file storage, and environment variables; the site built during the conversation used How I AI’s purple, black, and white branding, categorized video tips by AI tool and function, and could be shared publicly or restricted to individual email addresses through ChatGPT login. Nick Baumann’s UGC Video plugin processed roughly 20 clips in the live run by extracting transcripts, reviewing frames, selecting takes, and assembling an organic vertical video; for another workflow, he uploaded 50 or 60 clips for three videos, dictated the narratives, left it running overnight, and returned to completed outputs, including automated moving blurs over sensitive on-screen material.
