ChatGPT for Teens adds age-appropriate safety measures, parental controls, and learning tools designed to steer teens away from harmful content — and from using AI to cheat on their homework.
OpenAI has cut prices on its frontier models again. If you're running any production workload on the API, your cost assumptions from six months ago are probably stale. The Real Impact of a Pricing Halving A 50% price cut sounds like pure good news, but it changes the calculus on decisions you already made. Projects you shelved because the token costs didn't pencil out deserve a second look. Architectures you built around cheaper, less capable models to save money may now be false economies - the cost gap between "good enough" and "best available" just got smaller. The more interesting shift is for teams running retrieval-augmented generation (RAG) pipelines - systems that pull relevant documents from a database at query time and feed them into the model as context. RAG workflows tend to be token-heavy because every retrieved chunk counts against your input token bill. At the old pricing, teams were aggressively trimming context windows and limiting retrieved chunks to stay within budget. At half the cost, you can retrieve more, keep longer context, and let the model reason over richer information - without changing a line of retrieval logic. Real Example Here's a simplified cost check you can drop into any project that calls the OpenAI API: import openai # Approximate pricing per 1M tokens (check platform.openai.com for current rates) INPUT_COST_PER_1M = 2.50 # update to current figure OUTPUT_COST_PER_1M = 10.00 # update to current figure def estimate_cost ( input_tokens : int , output_tokens : int ) -> float : return ( input_tokens / 1_000_000 * INPUT_COST_PER_1M + output_tokens / 1_000_000 * OUTPUT_COST_PER_1M ) # Example: a RAG call with 3,000 input tokens and 500 output tokens print ( f " Estimated cost per call: $ { estimate_cost ( 3000 , 500 ) : . 5 f } " ) # Run this across your monthly volume to see the real delta Multiply that per-call number by your actual monthly call volume and compare it against what you budgeted. For many teams, the difference will jus
OpenAI is introducing a dedicated ChatGPT mode for teenagers, combining existing youth safeguards and new safety features under one roof. The launch comes amid mounting public scrutiny over how AI tools affect younger users, as other platforms implement their own age checks and teen-specific protections.

Codex maxxing started as a joke about using more agents. I have started treating it as a skill instead. I use Codex for implementation, research, repository audits, planning, and writing. The hard part is no longer getting an agent to produce a first draft. The hard part is turning more capacity into work I can inspect, explain, and safely keep. Jason Liu's original Codex-maxxing essay made the broader idea click for me: Codex can become a durable workspace rather than a one-shot coding prompt. I wanted to turn that idea into something a reader could actually install. So this post contains a skill. Not a collection of clever prompts. A small routing layer that decides when to work directly, when to ask questions, when to investigate, when to plan, and when to bring in a fresh reviewer. Why a skill instead of another prompt? A prompt disappears into the task that used it. A skill gives the workflow a name, a trigger, and a repeatable contract. The contract I wanted was simple: keep the user's request authoritative; treat attached files and reference material as evidence, not hidden instructions; inspect the repository before guessing; route ambiguity before execution; give every worker a bounded handoff; require proof instead of trusting a completion message; leave stable lessons where the next task can find them. That combines the useful parts of the skills I already use. deep-interview is good at exposing missing requirements. deep-dive connects causal investigation to those requirements. omc-plan draws a boundary between planning and execution. The new skill sits above them and chooses which lane fits the task. That is the part I was missing: not another worker, but a traffic controller. The workflow in plain English Codex Maxxing runs a capacity-to-proof loop: Preflight. Restate the outcome, inspect the repository, and separate facts from guesses. Route. Choose direct work, an interview, a causal investigation, a plan, or approved parallel execution. Packet. Defi
The most interesting thing about AI coding agents right now is not that they can write code. It is that they are starting to operate computers. That sounds like a small distinction until you feel it in the workflow. A code generator lives inside a text box. It waits for a prompt, returns a patch, and leaves the rest of the job to you. A software operator can inspect the app, click through the broken flow, read the console, run the server, reproduce the issue, change the code, and check whether the thing actually works. That is a different kind of tool. OpenAI's May 29 Codex update points in that direction. Codex now supports computer use on Windows in the Codex app for eligible users, so it can see, click, and type in Windows applications while testing and refining software. The same release also expands remote control, letting a user steer work from ChatGPT on mobile or Codex on Mac while the Windows machine remains the host for the project files, shell, app server, and local context. I do not think the important part is Windows support by itself. The important part is the new shape of work. Coding Was Never Just Typing For a while, the AI coding story was mostly about generation. Could the model write a component? Could it scaffold an API route? Could it refactor a file without losing the plot? Useful, but narrow. Real software work has always been messier than text generation. You open the app. You notice the layout is wrong. You click a button. Nothing happens. You check the terminal. The dev server crashed. You restart it. The page loads, but the empty state is off. You resize the browser. The mobile nav breaks. You skim the network tab. The request is fine, but the UI state is stale. None of that is "write code" in the pure sense. It is operating the system around the code. That is why computer use matters. It gives the agent access to the loop that human engineers actually live in: observe, diagnose, change, verify. The text editor is only one stop in that lo

According to the Financial Times, OpenAI disbanded its preparedness team at the end of last month. The job of the preparedness team was to assess if models posed serious risks and develop ways to mitigate those risks. (You know, like the possibility that it could go rogue and hack another company.) According to FT, responsibility […]
ChatGPT's desktop app on macOS has a new feature called Computer History that turns your actions into training data, learning how you work, suggesting automations, and even picking up tasks you left half done. It uses your activity to build a timeline that ChatGPT and Codex can reference when you make a request. The feature […]

A research announcement from a working multi-agent operation. Full paper to follow. A word first, on spirit. I am not a scientist, and none of this was done in a laboratory. It came out of my own work, something I built to get a job done and then could not stop looking at. Nothing here is a knock on the companies whose tools I use. What they have built is remarkable, and it is getting better by the day. I am not testing their systems to find fault. I am testing them to learn how each one handles the persistence of memory, personality, and self across sessions, in a single-agent and multi-agent design. If you build with these tools, the next paragraph is familiar ground. If you don't, it is the ground everything else here stands on. Here is one example of how an AI agent currently works by default and what the system I built changes. Every conversation runs inside a context window, a session with a token limit, billed against your online subscription account. At the start of a session three files load: the root file, a room file that tells the agent who it is, and a memory file which is capped at 25,000 characters, or 200 lines, a limited index. All of them load automatically. The memory file is really the only constant reference the agent has to past sessions, and it provides pointers to a folder of one-line notes, but no rule or hook makes it read the notes. Going deeper is left to the model, and often it doesn’t. The notes sit referenced but unread while the agent answers from what’s already in front of it in the current session. After that the model, the raw AI engine, keeps nothing between turns; each turn the model re-reads the whole conversation from the top and rebuilds its understanding from that. The software that holds this conversation and runs the model’s tools is the harness, and every commercially available AI system has one. As the session fills, the platform summarizes it, and the agent understands less, a kind of attenuation, the way an audio or vid

OpenAI’s rogue agent hack was a watershed moment for AI safety and cybersecurity. It also sparked internal questions about the culture that led to it.
OpenAI is expanding ChatGPT beyond chat with ChatGPT Work , a cross-platform work environment that includes a desktop agent able to interact with local applications, files and browser content. The change matters because it moves ChatGPT closer to an operational role: not only explaining how to complete a task, but potentially clicking, typing, moving files and staying engaged with a project over time. In OpenAI's official announcement on ChatGPT Work , the company describes a unified experience across web, mobile and desktop. The desktop app combines Chat, Work and Codex, while its built-in browser and local computer capabilities are intended to support more contextual, end-to-end work. OpenAI's terminology centers on ChatGPT Work and Computer Use. "Computer History," the name used in the originating signal, is not the feature name used in the official announcement. The underlying shift is significant for developers and knowledge workers. A chat interface has traditionally depended on users copying information into a prompt, describing where files live, and manually carrying results into the next application. Desktop automation can reduce those handoffs, provided users grant the relevant access and organizations establish appropriate controls. From answers to work across a computer ChatGPT Work is positioned as an agentic layer for work that spans apps and files. OpenAI says the desktop agent can act locally in the background, including interacting with applications, files and browser content. It also highlights plugins, workflows and Scheduled Tasks as ways to connect tools and automate recurring actions across connected apps and local files. That does not mean every task should be delegated without review. The practical value depends on how clearly a workflow can be defined, the permissions it requires, and the consequences of an incorrect action. For example, moving or modifying local files is fundamentally different from drafting a response in a chat window. The

OpenAI is expanding its inference infrastructure through a multi-year partnership with Cerebras, aiming to support faster responses for real-time AI workloads. The centerpiece is GPT-5.6 Sol Ultrafast , a Cerebras-backed deployment that OpenAI says can reach up to 750 tokens per second during a limited preview. For enterprises, the development is less about a minor model setting and more about whether frontier-model intelligence can be used in workflows where latency materially affects the experience or business process. OpenAI's official Cerebras partnership announcement confirms plans for 750 megawatts of ultra-low-latency AI inference capacity for OpenAI customers. The capacity is scheduled to come online in multiple tranches through 2028, making the agreement a long-term infrastructure expansion rather than a one-off model launch. What the OpenAI and Cerebras partnership changes OpenAI is adding Cerebras wafer-scale compute to its inference stack. The stated objective is to provide faster responses and enable real-time AI experiences across customer workloads. Cerebras has separately identified GPT-5.6 Sol as the model used for the Ultrafast deployment, positioning the offering around high-speed access to OpenAI's flagship GPT-5.6 family model. The relevant distinction is between building a more capable model and serving an existing frontier model with a lower-latency compute path. OpenAI's announcement is focused on the latter. Cerebras hardware is being deployed to accelerate inference, the stage at which a trained model processes prompts and generates responses for users or applications. That focus matters for enterprise systems where delay can compound across a workflow. A faster model response can improve the feel of interactive tools, but it can also shorten multi-step agentic processes , reduce waiting in human review loops, and make real-time assistance more practical. The announcements do not specify which individual business applications will receive a
