At DevDay 2026 on 29 September, OpenAI announced new ways to work with ChatGPT and the technology behind it. The biggest changes include an assistant that can keep working on your behalf, a more affordable AI model and a premium option for faster responses.

If you run a Swiss business and know ChatGPT mainly as a place to ask questions or draft an email, these are the developments worth understanding.

01

Dots: an assistant that keeps working

Dots is OpenAI’s new AI assistant that can keep working between conversations. You can give it a task, connect the apps it needs and come back to review its work. It can remember your preferences and follow up as a project develops.

That is a useful step beyond asking a question and receiving an answer. You might ask it to research a supplier, prepare a meeting brief or keep track of a project. These are possible starting points, rather than promises that every task will work perfectly.

You choose which apps it can access and set rules about when it must ask for approval. Important work still needs your review.

For a busy business owner, the attraction is simple: less time directing every small step.

In Switzerland, Dots is rolling out to Business Premium users. Pro users in Switzerland are excluded from the initial rollout. Enterprise users can try the beta when their administrator enables it. Access is gradual and may take several days to reach an eligible account.

What changed in AI cost and speed?

There are two separate announcements here: a lower-cost model and a faster premium service.

A more affordable AI model

An AI model is the engine that does the thinking and writing behind an assistant. OpenAI’s new GPT-6.1 Sol approaches the capabilities of its more powerful GPT-6 Astra model in several of OpenAI’s tests.

Its standard prices for processing incoming text and generating responses are one-fifth of Astra’s. That comparison applies to the developer service used to put AI into software. It does not mean your ChatGPT subscription becomes 80% cheaper.

Lower running costs could make useful business applications more affordable, such as reading documents or preparing customer replies.

Sol is available in ChatGPT Work, the part of ChatGPT for carrying out longer tasks, and in Codex, explained below. Developers can also use it in their software. It is not yet available in ordinary ChatGPT chat.

Faster responses when speed matters

OpenAI also announced Ultrafast, a premium service that generates text faster. The benefit is less waiting when you or your software need a response. It costs more, so it is a separate choice from the cheaper Sol model.

GPT-6 Astra Ultrafast is available now in the developer service and on eligible Pro 500 and Enterprise plans in Work and Codex. The Sol version is coming later.

Faster text generation does not make every task faster by the same amount. Looking up information and checking the result still take time.

03

Private Intelligence: more control over sensitive business data

For a Swiss company, using AI with client documents or confidential plans raises a practical question: who can access that information?

OpenAI’s Private Intelligence announcement addresses this with two developments:

  • Private Safety Processing: automated safety checks without giving OpenAI staff access to the content being checked. OpenAI does not retain the prompts and responses for these checks. Instead, encrypted safety records are kept in company-controlled cloud storage for 30 days.
  • Private Inference: a preview planned for this autumn. It aims to protect data while the AI processes it, using a protected computing environment with controls that can be verified.

Private Safety Processing is for businesses integrating AI into their software through OpenAI’s developer service. Organisations already approved for Zero Data Retention can configure it now; others need approval first. It requires technical setup.

For Swiss firms handling confidential information, these developments could make more AI projects feasible. The useful next step is to assess whether the available controls match the data and access requirements of a specific project.

04

Space and Pages: your team and AI on the same document

ChatGPT is becoming a place where colleagues can work together with AI. Space brings shared documents and files into one place. Pages are the documents inside it: you can write, research, add charts or images, and invite colleagues to contribute.

People with edit access can work on the same page at the same time and leave comments. Each colleague can use their own ChatGPT to help with the shared document. Where Dots is available, they can also bring their own dot into the work by mentioning it on the page or in a comment.

For example, one colleague could ask for a clearer summary while another adds figures. A dot could research an open question and add its findings to the same document. The team can then review the work together.

Sharing a page does not share private chats or personal memory. What gets written on the page is visible to people who have access.

Space and Pages are available on Pro, Business and Enterprise on web and desktop. Mobile supports finding, reading and sharing pages; editing is coming later. Collaborative slides are planned for the coming weeks.

More ways to work with colleagues

  • Team Tasks: recurring work such as a weekly project update, available on Business and Enterprise.
  • ChatGPT in Slack and Microsoft Teams: ask for help directly in a team conversation.
  • Meetings plugin: meeting summaries and action items, initially in beta on the macOS desktop app for Pro and Business users.
05

Apps that work inside ChatGPT

A plugin connects ChatGPT to other tools or adds new capabilities. OpenAI’s new plugin extensions go a step further: an app can appear in the sidebar or in a panel next to your conversation. You can work with it without leaving ChatGPT.

This can serve both customers and internal teams. A software company could offer its app publicly. A business could also make a private plugin available only inside its company workspace.

The extension determines how the app appears. Publishing and sharing settings determine who can use it. Publishing privately to a company workspace does not put the app in the public directory.

06

Codex: more help with building and checking software

Codex is OpenAI’s tool for developing software with AI. At DevDay, OpenAI expanded its cloud capabilities, code reviews and security checks. Developers can let it investigate problems and prepare fixes while they are away.

For a business commissioning a website, customer portal or internal tool, this is relevant to how the development team works. It can help with implementation and review; the team still needs to check that the result meets the business requirements.

Where should a Swiss SME start?

Our view at Swiss Product Studio: Dots and more affordable capable models are the developments to watch most closely. They could bring useful assistance within reach of more small teams. Faster responses matter where waiting is a real frustration.

You do not need to adopt every announcement. Start with one task that takes time each week, and see whether the tools available to your team can help. Before connecting company information, agree what can be shared and who checks the result.

SPS helps businesses choose useful applications and connect AI to their existing tools. If you want help finding a starting point, bring one recurring task to a 30-minute operations review. We will look at how it works today and discuss what could improve it. No technical brief is needed; the conversation is in English.
