OpenAI says Dots are always-on agents running on GPT-6 Astra with a dedicated cloud computer, and that they reach over 4,000 apps through a plugin ecosystem. For engineers, the interesting question is whether a persistent agent that idles and polls thousands of integrations around the clock remains economically viable at Astra's price point, or whether a cheaper successor model shifts the unit economics enough to make always-on workloads practical.
Why it matters
For data and AI engineers, the most immediate consequence is how Dots reshape cost modeling inside a team.
OpenAI confirms that the initial dot is included at no additional charge for Pro and Business Premium subscribers in eligible regions. For engineers assessing the cost of persistent agents on GPT-6 Astra against scheduled pipelines, this complimentary access offers a low-risk opportunity to test the system.
What happened
OpenAI held DevDay 2026 on September 29 at Fort Mason in San Francisco. Simon Willison's live blog also highlights GPT-6.1 Sol, which offers near-Astra performance at one-fifth the price, alongside an Ultrafast tier that runs eight times faster at six times the cost.
On availability, Willison notes Dots went live for Pro and Enterprise subscribers on launch day itself.
How it works
Under the hood, a Dots instance is a long-lived process hosted in OpenAI's cloud rather than a local CLI session. For enterprises, Microsoft Agent 365 supplies the governance and security perimeter around those persistent sessions.
The economics are where the design decisions get interesting. Simon Willison reports that GPT-6.1 Sol delivers near-Astra intelligence at roughly one-fifth the per-token cost, which changes the unit economics of keeping a dot alive for hours. A Pro 500 subscription bundles Ultrafast access with twenty-five times the usage allowance of a Plus plan, effectively pricing sustained agent workloads into a flat monthly fee. The trade-off is straightforward: Astra-backed dots get the strongest reasoning and widest tool coverage, but at a premium that Sol largely erases for non-latency-critical tasks.
OpenAI's real-time stack transmits audio and JSON control events over a single WebRTC channel, while an optional sideband WebSocket handles server-side integrations. Client delegation allows connections to arbitrary backends, though this mode is fixed at session creation and cannot be changed during the conversation. Partners including LiveKit, Twilio, Telnyx, and Daily/Pipecat supply the necessary telephony and media infrastructure for these server-side paths.
