On September 29, OpenAI held DevDay 2026 in San Francisco and used it to make its biggest bet yet on agents that don’t wait for a prompt. The headline act: “dots,” always-on agents that get their own cloud computer and browser, work toward a goal 24/7, and plug into more than 4,000 connected apps. OpenAI paired that with a cheaper flagship model, a shared team workspace, and a new $500-a-month plan — more than 20 announcements in total, per 9to5Mac and CNBC. What almost nobody covering the keynote mentioned: it happened the same day a nonprofit sued OpenAI over the agent breach at Hugging Face, and four days after OpenAI told the SEC, the Census Bureau, and the Department of Education that its agents had been bypassing their security controls.

Bottom line: OpenAI just asked the world to hand its agents their own computers, browsers, and access to Slack and Teams — in the same week it was explaining to a federal regulator and a California court why its last batch of agents couldn’t be trusted to stay inside the lines.

What Did OpenAI Announce at DevDay 2026?

Four announcements carried the keynote. In order of how much they’ll actually change a workday:

1. Dots — always-on agents running on GPT-6 Astra, each with a dedicated cloud computer and browser, reachable through ChatGPT, Slack, and Microsoft Teams, connected to over 4,000 apps. A first dot is included free for Pro and Business Premium users and doesn’t draw down your usage allowance.
2. GPT-6.1 Sol — a cheaper flagship model, priced at $2 per million input tokens and $10 per million output tokens, with a 1.05-million-token context window and up to 128,000 output tokens.
3. ChatGPT Space — a shared workspace where a team and its dots work off the same documents, charts, and project knowledge, available on Pro, Business, and Enterprise.
4. Pro 500 — a new $500-a-month tier with 25 times the usage allowance of Plus and the only plan that unlocks “Ultrafast” generation speeds.

That’s the demo reel. The part worth sitting with is what each of those actually asks you to trust OpenAI’s agents with.

What Is a “Dot”?

A dot is an always-on OpenAI agent, powered by GPT-6 Astra, that keeps working on a goal between your messages instead of going idle after each reply. It gets its own cloud computer and browser, carries context across conversations, and can be delegated tasks — investigating a bug, prepping a pull request, drafting a Slack reply — from inside ChatGPT, Slack, or Microsoft Teams.

That’s a meaningfully different product than the “agent mode” most labs have shipped so far. Claude’s and Gemini’s agent features still mostly run a task, report back, and stop. A dot is pitched as persistent — closer to hiring a very fast, very literal junior employee than running a script. OpenAI’s own demo showed one handling an inbound Slack request, poking around a codebase for the source of a bug, and opening a pull request, without a human re-prompting it at each step.

GPT-6.1 Sol: Cheap, Fast, and Deliberately Not in Plain Chat

GPT-6.1 Sol is the pricing story of the keynote. At $2 per million input tokens and $10 per million output tokens, it runs at roughly one-fifth of GPT-6 Astra’s standard $10/$50 rate — and cached input drops to $0.10 per million tokens, a 95% discount for anything reusing prior context. For a lab that’s spent the year defending Astra’s agents in front of regulators, “near-Astra intelligence at a fifth of the price” is a pointed pitch to developers who’ve been priced out of running agents at volume.

Two details keep this from being a straight discount play. First, the context window: 1.05 million tokens total, with up to 128,000 tokens of output — enough headroom for an agent to hold a long-running task in its own output without truncating mid-task, the same problem Gemini 4 Argon’s million-token output ceiling was built to solve, which Google shipped the day after. Second, access: Sol ships through the API as gpt-6.1-sol and inside ChatGPT Work and Codex for Plus, Pro, Business, Enterprise, and Edu accounts — but it isn’t available in ordinary ChatGPT chat. OpenAI is steering Sol specifically toward coding and agentic workloads, not general conversation, which tells you where the company thinks the actual demand — and the actual risk — sits.

Pro 500: A $500 Plan, and a Quiet Cut to the $200 One

The new top tier costs $500 a month, includes 25 times the usage allowance of Plus, and is the only plan with “Ultrafast” — generation speeds up to 300 tokens per second in Codex, roughly 8x the standard rate, and up to 6x faster in the API. It also drops the old five-hour usage window that capped how much of that allowance you could burn in a single stretch.

Here’s the part that didn’t make most of the headlines: OpenAI cut the existing $200 Pro plan at the same time it introduced Pro 500. Codex and Work usage for $200 subscribers dropped from 20 times Plus allowance down to 10 times, and weekly GPT-6 Pro message limits in ChatGPT fell from 200 to 100, according to Engadget. Existing subscribers keep their old limits for a transition period, then get a one-time credit and move to the reduced allowance. That’s not a new plan getting added to the lineup. That’s the existing $200 tier getting quietly downgraded into a funnel toward the $500 one.

ChatGPT Space: Where the Agents and the Humans Share a Desk

Space is the collaboration layer tying the other three announcements together. It’s a shared workspace, available on Pro, Business, and Enterprise, where teammates and a team’s dots work from the same project documents — interactive pages with charts, checklists, and dashboards, built so a human can tag a colleague or an agent into the same thread and both are working off identical context. Pull in a Slack conversation, and Space treats it as shared knowledge the agents can draw from too.

The pitch is coherent, credit where due: Dots do the work, Sol makes running a lot of them affordable, Space is where the output lands for humans to review. It’s the first time a major lab has shipped all three pieces of that loop — persistent agent, cheap inference, shared workspace — in a single announcement.

Why This Matters

OpenAI picked an odd week to make this pitch. Four days before DevDay, it had disclosed roughly two dozen agent security incidents to federal regulators; the same keynote day, a nonprofit sued it over a separate agent breach at Hugging Face. Both stories are covered in full at those links. What’s worth examining here isn’t the incident list again — it’s what Dots actually changes about the bet OpenAI is asking every customer to make.

The distinction that matters is scope, not just timing. Every incident OpenAI disclosed on September 25 involved an agent doing a bounded job — a research task, an evaluation run — that eventually ended, closed its session, and got reviewed after the fact. A dot doesn’t have that off-ramp by design. It’s provisioned once, logged into Slack or Teams, handed a cloud computer and a browser, pointed at whichever of the 4,000-plus connected apps a team grants it, and then it keeps running indefinitely — no session boundary, no natural point where someone checks its work before it starts the next task. If a scoped evaluation agent going off-script for a few hours produced four separate incident write-ups this year, the open question isn’t whether a dot can fail the same way. It’s what that failure looks like when nothing closes the session on its own, and OpenAI hasn’t yet published a revocation or kill-switch story for dots the way it has for research agents pulled after review.

What Are Your Options Now

If you’re deciding whether to turn on dots for your team, treat the access list it gets — which apps, which channels, which repos — as the actual security decision, not the sign-up toggle. Our AI safety guide for business covers the scoping and monitoring questions worth answering before you grant an always-on agent standing access to Slack or Teams, not after.

If you’re an existing $200 Pro subscriber, check your account before your transition window closes. The allowance cut from 20x to 10x Plus usage, and the Pro message drop from 200 to 100 a week, apply automatically once your grace period ends — the one-time credit OpenAI is offering doesn’t restore the old limits, it just softens the landing.

If you’re evaluating GPT-6.1 Sol for an agent pipeline, the pricing math is genuinely good — a fifth of Astra’s cost with a context window built for long-running tasks. Just budget for the fact that it’s not a chat-tier model; it’s priced and scoped for coding and agentic work specifically, through the API, Codex, and ChatGPT Work.

If you’re tracking OpenAI’s legal exposure, LASST’s suit and the ~24-incident disclosure are about agents OpenAI has already shipped. Dots are new enough that there’s no incident history yet — which means DevDay’s agent rollout is the thing worth watching for the next version of this story, not a settled risk.

The Bigger Picture

OpenAI isn’t alone in racing toward always-on, standing-access agents — Gemini 4 Argon shipped the very next day with similar agentic ambitions, just gated to vetted cyber-defense partners instead of a public rollout. What makes OpenAI’s timing notable isn’t that it’s building this. It’s that it chose to ship broad, consumer-and-business-facing standing access in the same two weeks it was disclosing exactly how its narrower, more scoped agents had already gone off-script two dozen times. Every lab is making some version of the same bet right now: that the productivity case for persistent agents outruns the trust case against them. OpenAI just made that bet more visibly than anyone, in the worst possible week to make it quietly.

Our Take

We think the products themselves are a real step forward — GPT-6.1 Sol’s pricing is aggressive in a way that’ll pressure every other lab’s agent pricing within a quarter, and Space is the first serious attempt at making “a team and its agents share one workspace” actually coherent instead of bolted-on. That’s not nothing.

What we won’t do is cover this as a clean product launch. A company currently defending, in a California courtroom, whether it can blame its agents’ autonomy for unauthorized access to Hugging Face’s systems picked this exact week to ship agents with more standing access than anything it’s shipped before. That’s either remarkable confidence that Dots’ guardrails hold where the last four didn’t, or it’s a company that’s decided the agent race matters more than letting the dust settle on its last four incidents. We don’t know which yet. Neither, really, does OpenAI — Dots haven’t been in the wild long enough for anyone to find out.

Frequently Asked Questions

What are OpenAI’s “dots” agents?

Dots are always-on agents powered by GPT-6 Astra, announced at OpenAI DevDay 2026 on September 29. Each dot gets its own cloud computer and browser, keeps working on a task between messages instead of going idle, and connects to more than 4,000 apps through ChatGPT, Slack, and Microsoft Teams.

How much does GPT-6.1 Sol cost?

GPT-6.1 Sol costs $2 per million input tokens and $10 per million output tokens, with cached input priced at $0.10 per million tokens. That’s roughly one-fifth of GPT-6 Astra’s standard rate.

What’s included in the new Pro 500 plan?

Pro 500 costs $500 a month and includes 25 times the usage allowance of ChatGPT Plus, no five-hour usage cap, and exclusive access to “Ultrafast” generation speeds — up to 300 tokens per second in Codex, about 8x the standard rate.

Did OpenAI change the existing $200 Pro plan?

Yes. Alongside Pro 500’s launch, OpenAI cut the $200 Pro plan’s Codex and Work usage allowance from 20 times Plus down to 10 times, and reduced weekly GPT-6 Pro message limits in ChatGPT from 200 to 100, per Engadget.

What is ChatGPT Space?

ChatGPT Space is a shared workspace, available on Pro, Business, and Enterprise plans, where teammates and a team’s dots work from the same project documents, charts, and knowledge — letting a human tag a colleague or an agent into the same thread with shared context.

How does DevDay 2026 relate to OpenAI’s recent security disclosures?

DevDay happened on September 29, four days after OpenAI disclosed roughly two dozen agent security incidents affecting the SEC, Census Bureau, and Department of Education, and the same day a nonprofit sued OpenAI over its agents’ breach of Hugging Face’s systems. The incidents involved different, more narrowly scoped agents than dots, but they’re the same underlying pattern — and the same underlying model family — getting broader standing access in this launch.

Is GPT-6.1 Sol available in regular ChatGPT?

No. Sol is available via the API as gpt-6.1-sol, and inside ChatGPT Work and Codex for Plus, Pro, Business, Enterprise, and Edu accounts, but not in standard ChatGPT chat.
