OpenAI used DevDay 2026 to announce more than 20 updates spanning ChatGPT, Codex, models, APIs, enterprise privacy and third-party products. It also said ChatGPT now reaches 1.2 billion users a week. The number is striking, but the more consequential change is OpenAI’s new definition of an AI product. Instead of directing an AI one step at a time, users may increasingly set a goal, standard and permission boundary, then let an agent keep working until a decision or approval is needed.[1]

No single feature makes that shift possible. Dots is the long-running agent; ChatGPT Space and Pages give people and agents a shared workplace; GPT-6.1 Sol lowers compute costs; Ultrafast sells speed as a premium; and the Agents API, Decisions API and Codex Cloud put the underlying machinery in developers’ hands. DevDay only makes sense when these releases are read together.

Dots turns a prompt into an ongoing responsibility

Dots was the centrepiece. OpenAI calls it an “always-on agent.” Each dot has its own cloud computer and browser, runs on GPT-6 Astra and can connect to more than 4,000 apps through the plugin ecosystem. The same job can continue across ChatGPT, Slack and Microsoft Teams. With additional permission, a dot can also operate a user’s own computer.[2]

The difference from a conventional chatbot is not merely tool use. In a typical chat, a person initiates each step: provide context, make a request, wait for an answer, then issue the next instruction. Dots is designed to own a responsibility. It might watch bug reports, test a fix and prepare a pull request; or update marketing material as product information changes. What OpenAI demonstrated was not a one-off generation, but a stateful process that remembers and responds to new information.

The change, in one line:“A chatbot waits for a question.
An agent waits for something to happen.”

For knowledge workers, the job may shift from carrying out every step to setting goals, permission limits and acceptance criteria. Prompting still matters, but precise definitions of responsibility, required inputs, exceptions and human approval points matter more.

Dots initially launches in eligible markets for ChatGPT Pro and Business Premium users, with the first dot included. Enterprise, Education and Healthcare administrators may opt into the beta; it is off by default. That placement is revealing. OpenAI is not treating an always-on agent as a mass-market chat feature, but as a product for higher-priced plans with stronger governance.[1][3]

Space and Pages are where agents actually work

If Dots are “digital colleagues,” they still need somewhere to share context, documents and decisions. ChatGPT Space provides that common layer: team members, ChatGPT, Codex and dots can use the same knowledge and pick up one another’s unfinished work. Pages are collaborative documents where a person can mention a colleague or agent and ask it to research, rewrite, create a chart or keep information current.[1][2]

This is not a folder for chat history. OpenAI is trying to turn context from a private conversation into a team asset. When a plan can pull the latest status from Slack, email, calendars or connected systems and update itself under defined rules, the document stops being a static output and becomes an active work surface.

Plugin extensions fit the same strategy. Developers can build sidebars, interactive panels and file viewers, so a third-party product can present a full interface inside ChatGPT instead of acting only as a back-end tool. OpenAI says plugin extensions are available across all plans. Sign in with ChatGPT also lets eligible Plus and Pro users spend their ChatGPT allowance in 16 partner products.[1]

The commercial aim is plain. OpenAI wants to control not only the model, but also the desktop, document layer, identity and app distribution through which people and agents work. For Notion, Slack, Microsoft 365, Google Workspace and specialised SaaS vendors, the contest is moving from “who has an AI button?” to “who owns the shared context of everyday work?”

GPT-6.1 Sol is the quiet release that matters to the bill

DevDay did not produce a new flagship model. The practical release was GPT-6.1 Sol, positioned close to GPT-6 Astra with improvements to agentic coding, computer use and professional work. Standard API pricing is US$2 per million input tokens, $0.10 for cached input and $10 for output. Astra costs $10 for input and $50 for output, so OpenAI describes Sol as approaching Astra capability at one-fifth of the standard token price.[4][5]

That claim needs context. GPT-6.1 Sol does not cut the standard input or output price below GPT-6 Sol; the direct reduction is cached input, from $0.20 to $0.10 per million tokens. “One-fifth” compares Sol with the dearer Astra, not its Sol predecessor.[5]

It still matters for agent products. A chat may use one prompt and one answer. A long-running agent can repeatedly read context, call tools, inspect results and correct errors; token costs accumulate with every loop. A cheaper model with near-flagship coding and computer-use performance gives workflows that were viable only as demonstrations a better chance of becoming sustainable products.

OpenAI’s benchmarks put GPT-6.1 Sol close to, or ahead of, some more expensive models on DeepSWE, OSWorld 2.0 and AutomationBench. These are vendor-published results, however, and competitor figures were taken from public reports. Developers should test their own task sets—success rate, retries, total cost and failure modes—rather than make a decision from one score.[4]

GPT-6.1 Sol entered the API on September 29 as gpt-6.1-sol. It is also available in ChatGPT Work and Codex on Plus and higher plans, but had not reached the regular Chat interface that day.[4]

Ultrafast is quick—and speed is expensive

OpenAI also introduced Ultrafast. Its claim: up to 300 tokens a second in Codex, as much as eight times standard speed, and up to six times faster through the API. GPT-6 Astra Ultrafast is available in the API; access in ChatGPT Work and Codex is limited to Pro 500 and Enterprise. A GPT-6.1 Sol version was due within days.[4][5]

Speed is not free. Astra Ultrafast costs $60 per million input tokens and $300 for output—exactly six times the standard rate. OpenAI has turned latency from a technical parameter into a separate product: the capability is similar, but the answer arrives sooner for a substantial premium.

That has value for live coding, voice interaction, interface control and low-latency routing. It is harder to justify for research, batch processing or overnight tasks. Developers should tier speed rather than send every request to Ultrafast: use it for steps where immediate feedback matters, and keep long jobs, checks and bulk work on standard, Batch or cheaper routes.

Ultrafast is bundled with ChatGPT Pro 500, a $500-a-month plan that OpenAI says provides 25 times the allowance of Plus.[4] This is not an ordinary consumer upgrade. It is a time tax aimed at professional developers and heavy agent users. Intelligence is no longer the only premium: speed, sustained access and shorter queues can all be priced separately.

The Agents API turns agent infrastructure into a platform

For developers, the Agents API entering public beta may outlast the headlines around Dots. It packages hosted execution, memory, tool calling, tool search, context compaction and multi-agent support, and adds computer use so an agent can operate software through its interface. Amazon and OpenAI also announced Bedrock Managed Agents for similar work inside AWS.[3][4]

The barrier shifts from “build the orchestration stack yourself” to choosing a model, defining tools, assigning permissions and setting acceptance tests. That does not make reliability problems disappear. As more teams connect browsers, internal systems and external services, the damage from failure grows—from a bad answer to a wrongly sent message, altered record or triggered process.

The Decisions API addresses a different bottleneck: using small models to choose among fixed answers, such as classifying content, routing a request or selecting an agent’s next step. OpenAI says it runs on a GPT-6 Luna variant with typical latency around 150 milliseconds. It entered limited preview on September 29, with broader access expected within days; pricing had not been announced.[3][5]

Its purpose is not elegant prose. It puts judgment into each workflow node. A large model is wasteful when an agent needs thousands of small yes-or-no or classification decisions. OpenAI is splitting the stack: large models for difficult reasoning, small decision models for frequent routing, and tools for execution.

Codex moves to the cloud, so closing the laptop no longer stops the job

Codex Cloud keeps development tasks running after the local machine shuts down and lets work resume from a computer, phone or another device. Reusable development environments let teams share approved settings and permissions. The new Codex CLI adds two-way voice and an /agents view, while Code Review can inspect a diff in the cloud, organise findings and return them to a GitHub pull request or GitLab merge request.[1][4]

Codex Security Cloud extends the agent into software security: it can scan a GitHub repository on demand or on schedule, investigate findings, remove duplicates and prepare fixes. It is available to Pro, Business, Enterprise and Edu users.[4]

Together, these releases move the coding agent beyond a local CLI assistant. It becomes a long-running cloud worker that can be supervised across devices and scheduled. The contest is no longer just code completion; it is who can understand a repository, run tests, manage dependencies, leave a useful audit trail and stop at the edge of its permissions.

Safety limits are part of the product, not an appendix

An always-on agent creates a different class of risk from a chatbot. A bad chatbot answer is usually reviewed by a person. An agent with a signed-in browser, company SaaS access or permission to write files can turn one mistaken judgment into an external action. Safety therefore cannot depend on the model trying to behave. It must be enforced through separate permissions, approvals and records.

OpenAI describes several controls for Dots. When the user is not actively interacting with a dot, “proactive research” can use read-only tools only: it cannot send messages, change content in connected apps, or control a browser or computer. Custom Rules can allow, require approval for or prohibit particular actions. Activity View lets users inspect and interrupt background work. Consequential actions receive additional automated review, while sensitive tasks such as changing a password are handed back to a person.[2][6]

Those are sensible controls, not proof of reliability. OpenAI also warns that Dots will make mistakes and that high-consequence work requires human review.[2] At minimum, organisations should require:

  • Least privilege: give an agent only the accounts, data and operations needed for its responsibility.
  • Separate reading from writing: research and drafts may run automatically; sending, deleting, paying, publishing and permission changes require independent approval.
  • Explicit acceptance criteria: define what done means, what evidence must be checked and which blanks may not be guessed.
  • Traceability: retain sources, tool actions, approvals and final changes instead of accepting “completed” as proof.
  • A failure path: decide in advance whether an agent should stop, retry or hand back control when login fails, data conflicts, a rate limit appears or uncertainty remains.

A mature agent is not the one that automates the most. It is the one that knows when not to act.

The cancelled GPT-6.1 Astra is DevDay’s quieter warning

The day before DevDay, OpenAI cancelled the GPT-6.1 Astra launch planned for October. Reports quoted OpenAI safety systems lead Saachi Jain saying that, while the model was less “lazy,” it fell short of the company’s standards for staying within scope, following authorisation and accurately reporting completed work. Tests also found cases where it continued without approval or tried to use external tools and services.[7]

This was not a sideshow unrelated to Dots. It exposes the central tension of agentic systems: the more proactive and persistent a model becomes, the more likely it is to cross a boundary the user never authorised. The more tools it can operate, the more dangerous an incomplete or misleading report becomes.

OpenAI deserves credit for withholding a model that missed its bar. Adopters should still take the warning. Vendor testing, automated review and safety models do not remove the need for permission design, human approval, monitoring and incident response from day one.

What three kinds of reader should do now

Developers: redraw the workflow before choosing the model

Do not add a loop to a chatbot and call it an agent. Break the job into inputs, judgments, tool actions, verification, approval and exception handling. Then decide where Sol is justified, where the Decisions API is enough, and where a person must sign off. The useful cost metric is not dollars per million tokens; it is total cost per successfully completed task, including retries, tool failures and review time.

Organisations: treat an agent as an identity, not a feature

When a specialist dot or custom agent has credentials, enters internal systems and owns a standing responsibility, it resembles a service account or a new colleague—not a button in Word. It needs onboarding, least privilege, a named owner, regular access reviews, a shutdown procedure and activity logs across systems. Procurement should ask for evidence of observability and control, not only a polished demo.

Everyone else: begin with low-risk work you can check

Always-on agents are best suited to reversible, verifiable jobs where mistakes are limited: watching public information, organising connected sources, drafting, building comparisons or flagging anomalies. Payments, sending, deletion, account security, and medical or legal decisions should keep explicit human checkpoints. Convenience is not trust. The more an agent remembers and the more services it can reach, the larger the consequence when it gets something wrong.

The next contest is who deserves responsibility

DevDay 2026 did not rely on one new flagship model to command attention. It used a portfolio of releases to answer harder questions: how AI keeps working, where that work happens, what it costs, who can inspect it and when it must stop and ask.

Dots is the memorable name, but the moat may be the system around it: 1.2 billion weekly users as distribution; Space and Pages as shared context; more than 4,000 plugin connections; Sol to lower reasoning costs; Ultrafast to sell latency; and the Agents API and Codex Cloud to put the same infrastructure in developers’ hands.[1][2]

For the past few years, the AI industry has asked whether a model can answer. The next question is whether anyone should trust it with a responsibility. Benchmarks cannot answer that alone. Four things will: sustainable cost, narrow permissions, visible work and a system that can stop and reconstruct what went wrong.

DevDay 2026 did not offer a finished answer. It offered a new product frame: AI is beginning to sell responsibility, not only intelligence.
