On September 29, 2026, OpenAI held its largest DevDay to date in San Francisco and announced more than 20 products. ChatGPT now serves 1.2 billion weekly active users, a figure OpenAI disclosed at the event for the first time. The announcement that most affects brand visibility: Dots, always-on AI agents powered by GPT-6 Astra that connect to 4,000 apps and make proactive product recommendations without a user typing a single query. BrandCited's monitoring data shows ChatGPT is already the most-cited source for B2B purchase queries across the 8 AI engines BrandCited tracks. Brands absent from ChatGPT's knowledge base will not appear in Dots recommendations, and that gap compounds every hour those agents run.

OpenAI's DevDay 2026 produced more than 20 announcements on September 29, making it the company's largest product event since its founding. The five changes with direct implications for brand visibility are covered below.
Dots agents. Dots are always-on AI agents powered by GPT-6 Astra that live in the ChatGPT sidebar and run on their own cloud computers. Each dot connects to more than 4,000 apps via OpenAI's plugin ecosystem, including Slack and Microsoft Teams, and operates continuously without user direction. OpenAI described Dots as agents that "anticipate user needs rather than merely responding to direct prompts," according to the TechCrunch DevDay report. Dots are rolling out to Pro and Business Premium users in eligible markets first.
Plugin extensions. OpenAI launched plugin extensions, which let developers build full app experiences inside ChatGPT, not just text responses. OpenAI's own DevDay recap named Canva, Figma, and Adobe as early partners. ChatGPT surfaces relevant extensions automatically inside conversation, meaning brands with a plugin get placement visibility that brands relying on organic citation alone do not.

GPT-6.1 Sol. OpenAI released GPT-6.1 Sol on September 29, available at $2 per million input tokens and $10 per million output tokens, with a 1.05 million-token context window. The model is available via the OpenAI API as gpt-6.1-sol and to all Plus, Pro, Business, Enterprise, and Edu users.
1.2 billion weekly active users. OpenAI disclosed ChatGPT's weekly active user count for the first time at DevDay 2026: 1.2 billion. That figure is up from 400 million in February 2025, based on DemandSage's ChatGPT statistics tracker. Every week, 1.2 billion users ask questions that could reference your brand. Or not.
Agents API with computer use. OpenAI expanded the Agents API to support computer use, allowing developers to build agents that interact with software directly. Combined with the Decisions API, which routes queries through a constrained decision layer, these tools signal that ChatGPT is moving from a query-response tool to an autonomous task executor, per The Decoder's DevDay analysis.
Why do Dots agents change how ChatGPT recommends your brand?#
Dots agents make proactive recommendations. That is the distinction that changes the brand visibility calculation. Before Dots, a user had to type "what project management tool should I use" for ChatGPT to name a brand. After Dots, the agent proactively suggests tools as users work, learns preferences over time, and recommends options without an explicit query.
BrandCited tracks citation behavior across 8 AI engines and monitors ChatGPT separately for retrieval-augmented citations versus parametric-memory citations. ChatGPT in browse mode cites brands that appear in well-structured, indexed web content. Dots agents draw on ChatGPT's parametric memory and its connected app ecosystem. A brand not in ChatGPT's training data and not present in the plugin ecosystem has two reasons to be absent from Dots recommendations rather than one.
The reach multiplier is significant. ChatGPT reached 1.2 billion weekly users as of September 2026, according to OpenAI's DevDay 2026 disclosure. Dots start as an opt-in feature for Pro and Business Premium users, but OpenAI confirmed plans to expand to all users. The addressable audience for proactive brand recommendations inside ChatGPT is the full 1.2 billion user base.
How do ChatGPT plugin extensions give some brands a placement advantage?#
ChatGPT plugin extensions provide a placement signal that organic citation does not. When a user asks a question relevant to a brand's category, ChatGPT can surface that brand's extension inside the conversation interface automatically. OpenAI described this as "automatic recommendations in conversations to help users find developer-built apps," based on the CNBC DevDay recap.
Canva, Figma, and Adobe were announced as early partners, which means those brands gain a distribution channel inside ChatGPT that competitors without extensions cannot match. For every user session in which a design or creative question arises, ChatGPT can surface Canva or Figma natively.
BrandCited monitors brand mentions that originate from plugin suggestions separately from organic citations. BrandCited's free audit checks whether your brand has a presence in the major AI plugin ecosystems, including OpenAI's plugin marketplace, Perplexity's integrations directory, and Microsoft Copilot's plugin store. Gaps appear in the audit as medium-priority findings under the Ecosystem Presence category.
How does BrandCited audit your ChatGPT visibility?#
Track your AI visibility for free
See how ChatGPT, Claude, Gemini, and 4 other AI platforms mention your brand.
BrandCited runs probe queries across 8 AI engines, ChatGPT included, and returns a score from 0 to 100 for each engine plus a composite AI visibility index. The ChatGPT-specific score measures citation frequency (how often your brand appears), citation prominence (how early in the answer), and URL attribution rate (whether ChatGPT links back to your domain).
The audit also checks 30 content and technical signals that correlate with ChatGPT citation rates: schema markup completeness, FAQ section presence, structured author byline, entity clarity in the first 150 words of each page, and external citation footprint. Each finding carries a severity level and an exact fix, not a general recommendation.

1Run a free BrandCited scan today. The Dots rollout starts with Pro and Business Premium users. Check your current ChatGPT citation score before Dots reaches the full 1.2 billion user base. brandcited.ai returns your score in 30 seconds.
1Check whether your brand appears in ChatGPT for 5 queries your buyers actually use. Open ChatGPT and ask it to recommend tools in your category. If your brand does not appear in the first response, your brand is invisible to Dots agent recommendations for that query class.
1Add or fix FAQPage schema on your top 5 pages. BrandCited's audit data from 500 brands shows that FAQPage schema is missing on 78% of pages that have FAQ content in the body. ChatGPT extracts Q&A structure from FAQPage schema when generating answers. Missing schema means missing citation opportunities.
1Submit your brand to the OpenAI plugin marketplace. Plugin extensions are now a first-class placement channel inside ChatGPT. Review OpenAI's plugin development documentation and determine whether a plugin would give your product a native presence inside ChatGPT conversations.
1Publish or update a pillar article targeting your brand's primary query. ChatGPT's retrieval-augmented mode cites well-structured web content indexed before the query date. A pillar article with direct-answer H2 sections, complete schema markup, and 5 or more external citations gives ChatGPT a high-confidence source to cite.
