At DevDay on 29 September 2026, OpenAI announced Dots (always-on AI agents in ChatGPT), GPT-6.1 Sol (a cheaper model it says comes close to GPT-6 Astra), computer use in its Agents API, a bigger push on ChatGPT plugins, and team tools such as ChatGPT Space and Pages. For marketers, the big shift is from chatting with AI to handing it ongoing work.
OpenAI’s recap lists more than 20 launches, most aimed at developers. This article covers them all briefly, then focuses on the handful that change how marketing teams, agencies and site owners will work over the next few months.

1. Dots: AI agents that keep working when you don’t
Dots are the headline launch. OpenAI calls them “always-on agents built to handle everything.” Unlike a chat, a Dot keeps working in the background: it learns what you care about, checks your connected apps and gets tasks done for you to review.
A few details matter for business use:
- They run on GPT-6 Astra, OpenAI’s most capable model.
- Each Dot has its own cloud computer and browser, separate from your device unless you connect it.
- They connect to over 4,000 apps through ChatGPT plugins.
- You set the rules. Custom rules let you allow an action, require approval or block it, and an activity view shows what the Dot has done. OpenAI says some sensitive tasks, such as changing a password, always stay with you.
- Your first Dot is included in Pro and Business Premium plans. Enterprise, Edu and Healthcare workspaces get a beta that admins must switch on.
OpenAI’s own examples include one that is plainly about marketing: a Dot that picks out video clip moments, prepares show notes, drafts social posts and “learns what resonates with audiences.” Another example keeps launch materials up to date when a product’s scope changes. OpenAI also previewed “specialist dots” for roles such as email marketing, support and invoicing, currently in an Enterprise preview.
What it means for marketers: the jobs we listed in AI agents for small business (reporting, content repurposing, review monitoring) can now be handed to a Dot instead of being stitched together with automation tools. The same caution applies: start with approval required on anything that sends, publishes or spends money, and check the activity view regularly.
2. GPT-6.1 Sol: near-flagship results at a lower price
GPT-6.1 Sol replaces GPT-6 Sol as OpenAI’s recommended everyday model, just a week after GPT-6 Sol arrived. OpenAI says it approaches GPT-6 Astra on coding, professional documents, business workflows and computer use, at one-fifth of Astra’s standard token prices.
| GPT-6.1 Sol | |
|---|---|
| API price (per 1M tokens) | $2 input, $0.10 cached input, $10 output |
| Model ID | gpt-6.1-sol |
| Context window | 1,050,000 tokens (128,000 max output) |
| Knowledge cutoff | 30 April 2026 |
| In ChatGPT | ChatGPT Work and Codex for Plus, Pro, Business, Enterprise and Edu (not yet in regular Chat) |
The standard price is the same as GPT-6 Sol, but cached input is 50% cheaper, which helps if you reuse long instructions or brand guidelines in every request. OpenAI also says GPT-6.1 Sol makes fewer factual errors than GPT-6 Sol.
What it means for marketers: if you’re already using Sol for reports, briefs or drafts, switch to GPT-6.1 Sol and rerun a few of your usual tasks to compare. Our guide to the GPT-6 models and Claude Opus 5.5 vs GPT-6 Sol comparison explain how to test models on your own work.
3. The Agents API gets computer use
OpenAI’s Agents API, in public beta since 10 September, now supports computer use: agents that operate software through its interface, clicking and typing like a person. It also adds multi-agent support, tool search and automatic context compaction for long tasks. OpenAI says there are no extra fees beyond the tokens and tools an agent uses.
Separately, AWS customers can build OpenAI-powered agents that run entirely inside AWS through Amazon Bedrock Managed Agents.
What it means for marketers: expect more software built on this, including agents that fill in forms, update CMS pages or run ad-platform tasks through the same screens people use. It’s another reason to make sure your own website works for AI agents; see our guides to making your website ready for AI agents and AI browser agents.
4. ChatGPT plugins become a real distribution channel
Several announcements make ChatGPT plugins more capable and easier to find:
- Plugin extensions give plugins a home in the ChatGPT sidebar, interactive panels and custom file viewers. OpenAI showed Figma and Adobe examples.
- Better discovery: a Plugin Creator, a redesigned submission and review process, and improved ranking and recommendations.
- MCP Events: plugins can subscribe to events from connected apps (a new message, a changed document, a status update) and trigger automations.
- Sites with plugins for Business, Enterprise, Healthcare and Edu, so teams can use connected data inside ChatGPT Sites with the right permissions.
- Shareable profiles on every plan, including Free and Go, to showcase the Sites and plugins you’ve built.
What it means for marketers: for SaaS brands and agencies, a ChatGPT plugin is starting to look like an app-store listing. If your product has an API, a plugin could put it in front of ChatGPT users at the moment they need it. With improved “ranking and recommendations,” expect discovery inside ChatGPT to become a new optimisation job, much like app store optimisation.
5. ChatGPT for teams: Space, Pages, Slides and Slack
OpenAI also pushed ChatGPT further into everyday team work:
- ChatGPT Space: a shared place where teammates, ChatGPT and your Dot build on the same files and project context.
- Pages: collaborative documents where you can write, research, create charts and images together.
- Collaborative Slides: decks that several people and agents can edit at once, exportable to PowerPoint or Google Slides. OpenAI says these arrive in the coming weeks.
- Teams and team tasks: share pages, slides, plugins and spreadsheets, and schedule recurring team work.
- @ChatGPT in Slack and Microsoft Teams for Business and Enterprise.
- Meetings plugin (macOS beta): notes and action items saved to Space. OpenAI says audio is deleted once the notes are ready.
What it means for marketers: campaign plans, briefs and client decks can now be built and edited inside ChatGPT with the team. Before moving client work there, check your plan’s data settings and agree who reviews AI-generated material before it goes out.
6. Plans, pricing and sign-in
- Pro 500: a new $500-a-month ChatGPT tier with the most usage and access to GPT-6 Astra Ultrafast. OpenAI’s help centre now lists Pro 100, Pro 200 and Pro 500.
- Ultrafast: a premium speed tier with up to 8× faster output in Codex and up to 6× in the API. OpenAI hasn’t published a simple price multiplier on the pages we checked.
- Sign in with ChatGPT: users can log in to partner apps with their ChatGPT account, and in some tools use their ChatGPT plan’s allowance. OpenAI named 16 launch partners, including Notion, Vercel and Cognition’s Devin.
- OpenAI Marketplace: enterprises can apply part of their OpenAI spending commitment to approved partner software. Partners listed include HubSpot, Salesforce, Zendesk, Figma and Runway.
- Speed: OpenAI says API time to first token is 45% lower and tool calls are over 30% faster.
7. For developers and IT: Codex and privacy
Most of the rest is for engineering teams: Codex tasks that run in the cloud while your laptop is closed, a refreshed Codex command-line tool with voice steering, built-in code review for GitHub and GitLab, and Codex Security Cloud for scanning repositories. On privacy, OpenAI launched Zero Data Retention with Private Safety Processing, which it says allows automated safety reviews without OpenAI staff seeing the content, and previewed Private Inference for later this fall.
If your agency builds websites or tools, share this section with your developers. The rest of the team can skip it.
What to do this month
- Switch Sol users to GPT-6.1 Sol and compare output and cost on a few real tasks.
- If you’re on Pro or Business Premium, try one Dot on a low-risk, repetitive job such as a weekly report or content repurposing. Keep approvals on.
- SaaS and product teams: decide whether a ChatGPT plugin belongs on your roadmap, and read OpenAI’s updated submission guidelines.
- Check your data settings before putting client files into Space, Pages or Dots.
- Keep your website usable by agents: clear navigation, accessible forms and accurate structured data.
