OpenAI adds GPT-6.1 Sol to Work and Codex for agentic coding
OpenAI has added GPT-6.1 Sol to ChatGPT Work and Codex, with a rollout that started with Pro users and then expanded across paid and managed plans. The move points to a stronger focus on cheaper, practical agentic coding and computer use.
OpenAI brings GPT-6.1 Sol into Work and Codex
OpenAI added GPT-6.1 Sol to ChatGPT Work and Codex on September 29, 2026, a change that matters because it puts a newer model directly into the products developers and teams use for practical work. According to OpenAI, GPT-6.1 Sol improves on GPT-6 Sol in agentic coding, computer use, and professional work.
That framing is important. Rather than presenting the update as a general-purpose chat improvement, OpenAI is tying it to tasks where the model needs to take actions, work through software interfaces, and support day-to-day professional workflows. For readers watching AI tools, this is a clear signal that the product direction is centered on utility inside real work environments.
Why the rollout order matters
OpenAI says the rollout began with Pro users and then expanded to Plus, Business, Enterprise, and Edu users. That sequence suggests the company is placing the model first with users most likely to need faster, more capable work tools, then widening access across other paid and managed tiers.
For Enterprise and Edu customers, OpenAI says workspace owners can enable model access in Workspace settings > Permissions & roles. That detail matters for teams that manage model availability centrally, because access is not just a product announcement; it is also an administrative setting that determines when users can actually start working with the model.
A separate message for chat, work, and coding
OpenAI’s broader release context adds another layer. According to OpenAI, the models powering Work and Codex are not changing with the GPT-6 with Intelligent UI ChatGPT release. In other words, the company is separating the chat experience from the work-oriented models used in Work and Codex.
OpenAI also says GPT-6 with Intelligent UI rolled out globally to Plus, Pro, Business, and Enterprise in the Chat tab, then expanded to Free and Go starting the next day. OpenAI says GPT-6 in ChatGPT is powered by GPT-6 Sol for Plus, Pro, Business, and Enterprise, and GPT-6 Luna for Free and Go. The result is a product lineup that distinguishes between general chat access and the models intended for more specialized, work-focused use.
What this says about OpenAI’s packaging strategy
The practical story here is not only model capability, but also how that capability is packaged. OpenAI says GPT-6.1 Sol is part of the ChatGPT release notes, reinforcing that it is being positioned for work-oriented and agentic use cases rather than as a standalone benchmark event.
For teams deciding how to use OpenAI tools, the message is straightforward: watch the product tier you are on, check whether Work or Codex access is enabled, and confirm whether your workspace administrator has turned on the model. OpenAI’s recent releases suggest that frontier capability is increasingly being organized around professional workflows, access control, and product-specific use rather than a single universal model launch.
