Saw some asks about whether you should use dots or Codex. In reality they work great together! My dot is now my favorite way of using Codex. Less mental overload and the proactiveness is a lifesaver

Dots for saving money
My @OpenAI Dot sent an email last night on my behalf to negotiate the price of a fireplace I've been looking at. Woke up to an invoice for $1,000 off the full price from the company, ready to checkout. @AnthropicAI when can I try Duet?!

btw, am now leading ChatGPT/Codex Web + Desktop infra group if you’ve already made other developers meaningfully faster (platform, tooling, reliability, DX), the opportunity is to do the same work at AGI scale hit me up if interested

Most of you probably haven't noticed this, but dots have a new feature called multi-exec that we quietly released on friday. I've been using it all weekend on my personal dot and it's incredibly powerful. I'd like to share why this is a big deal and how to use it. At a high level, multi exec lets your dot run commands directly on any computer. This immediately turns your dot into a real virtual employee. Here's why it's a gamechanger: - you can attach a powerful machine with persistent storage to your dot (I attached it to my maxed out Mac Studio Ultra) - the dot can now drive your computer directly via Computer Use - this extends to browser use - all your websites stay logged in, residential ip etc - you set up all your CLIs and authentication ONCE and the dot can use them directly (no more fighting the default ephemeral cloud computer) - the dot can save skills locally for repeated workflows and subagents can use those directly - if you have a local obsidian memory vault for your agents, your dot can use that too - building ios app end to end and testing it in xcode, and showing me screenshots of progress as it works - all of the above also applies to any subagents your dot delegates to in the cloud (subagents share context unlike separate threads). To enable it, open the desktop app on your computer and hit "allow computer", then give your dot this prompt: "Hey I just connected my computer. Can you attach to it directly so it's your default computer and you can run commands directly on it? Do it in your root thread so that all subagents inherit this computer for running commands. Run whoami to run water through the pipes and verify it works end to end." I recommend attaching your dot to the most powerful machine you have and investing time into it up front: - Log into all the emails & websites you need e.g. stripe cli, gcloud, firebase, etc - Install and auth all the CLIs, git you need - Make sure computer use is turned on and allowed to use your computer while its locked - I also enabled Allow All for Browsing and Downloads so my dot could use computer use to download whatever it wanted from websites without asking me for approval for each domain (use at your own risk). - Important: I HIGHLY recommend to ask your dot to build out repeated workflows as skills, and iterate to make those skills bulletproof by running water through the pipes with its subagents. As of this weekend, my dot is sending me screenshots of its progress building my iOS app end to end on my Mac Studio Ultra via xCode, and clicking around and testing things end to end. It's able to configure things in stripe via the CLI and use websites when it needs to download images for my workflows. It’s night and day. Don't sleep on it.

You can now connect multiple local computers to the same dot and choose which one it uses for a task. It can build and test your app on a dedicated machine while you keep coding on your laptop.

Today is the day! Start building your own homebrew games inspired by the classics of the Game Boy Color for ModRetro Chromatic devices. Watch the video and read the article to learn how it works - very grateful too for @covacut 's brief (but painful) cameo 🙏

Ever thought about building your own games? The Codex edition @modretro Chromatic is now on Supply Co. With the ModRetro Chromatic plugin in Codex, you can design levels, animate sprites, and playtest on your handheld. Speedrun checkout while Codex builds your ROM 😉

Everyone keeps asking when I share demos to share prompts. 1. We have amazing demos and how-tos here: developers.openai.com/showca… 2. Most of the time, I did have some iterations that I need to format properly before just sharing raw like that.

A little upgrade: your dot can now use sign-in codes sent to your connected inbox to log in seamlessly on your behalf. When prompted, you can let your dot use the code once or always allow it to fill in. Lots more sign-in improvements coming soon!

Your teammate built a great site. Naturally, you have notes. With Remix, make your own version of a site by telling ChatGPT what you'd like to change. Then keep editing your copy in chat. Now rolling out to ChatGPT Business and Enterprise accounts.

We shipped a bunch of stuff in Agents API in October! And make sure you read to the end for some beta features 👀 The full list: - auto review: automatically review and approve or deny supported agent actions, similar to Codex’s “review for me” - automations: you or the agent can schedule future work, including recurring tasks. things like "check on x every hour" automatically work - update tools mid-session: change the tools available to an agent while a session is running - Artifact SDK: hosted sandboxes will now be better at spreadsheets, presentations and Word documents - (experimental) time awareness: experimental setting that gives the agent an understanding of time, so things like "do x in <10 mins" work well - sandbox prewarming: you can prewarm sandboxes before you need them (speeds things up by doing expensive work like installing packages) - async compaction: on by default, compacts context in the background so it doesn’t block the agent - cross-session prompt caching: system prompts are automatically cached across sessions - GPT-6 Astra Ultrafast: use ultrafast mode in the Agents API for faster output - sandbox snapshots: hosted environments can be restored after going idle, with their files intact - 12hr prompt caching: makes things faster for cases where your users talk to the agent less frequently - environment keys: create environment keys programmatically - turn-level history: inspect a specific turn and its subagent activity - vault metadata filtering: filter vaults by metadata when listing them - beta features we're working on: contact us to try them out - memory: agents will be able to remember stuff and search old messages across sessions - decisions api: give agents access to the decisions api, for faster performance on tasks that benefit from filtering, classification etc - budget control: give the agent a max dollar budget to work within - env pooling; we create a pool of vanilla containers, making performance faster for hosted sandboxes - v2 architecture: faster and more reliable across the board

PSA: you might have accrued plugins that are needlessly living in your context window I would recommend sending this prompt to your agent: What are the plugins I haven't used in the last 2 weeks? and depending on the answer: Remove the ones I've stopped using

Just promoted our new GPT-Live outbound telephony API to GA, allowing developers to make phone calls from their Live voice agent, via any SIP trunk provider (e.g, Telnyx or Twilio). Calls can use HD Voice and can send and receive keypad events (DTMF). developers.openai.com/api/do…

Some news: I’m joining OpenAI to lead product management for Core Products! I have a lot of respect for OpenAI for showing the world that scaling works, for bringing AI to over a billion people, and for believing great products are core to the mission. I’m excited to work with @thsottiaux, an incredible PM team, and everyone across OpenAI. Together, we’ll build agents that have your back and your team’s, and keep you in control, so you get more time for the people and work you love. Lots to learn, and lots to build. Please keep your feedback coming!
