The data for week 30 of 2026 reveals significant additions to the workspace permissions, exposing a list of unreleased model designations. The configuration includes access flags for models such as GPT-4.5, GPT-5-pro, GPT-5.1, GPT-5.2, o3, o4-mini, and a specialized gpt-lifesciences model. While these names appear in the payload, it is uncertain if they represent imminent releases or long-term internal placeholders.
The "ChatGPT Work" onboarding experience, which first appeared in week 29, remains actively configured. However, the explicit instructions regarding single-page website generation and artifact creation seen last week are no longer visible in the updated prompt, which may indicate a shift in focus or a simple truncation of the text in the current payload. Additionally, there is a clear expansion in specialized data retrieval, particularly in the healthcare sector.
The most prominent development in search capabilities is the addition of numerous health and medical databases to the approved connector scopes. The system is now configured to retrieve data from sources including Medicare Care Compare, PubMed, Clinical Trials, DailyMed, RxNorm, OpenFDA, and the NPI Registry. This aligns with the appearance of the gpt-lifesciences model permission and strongly suggests that OpenAI is preparing a specialized vertical search or retrieval environment for medical professionals and researchers.
In the context of local search, the enabled entity categories have been narrowed. Categories such as hotels, movies, and books were removed, leaving only local businesses, restaurants, and product rationale and reviews. Furthermore, the generation of map notes has been reduced from four lines to two. This indicates a refinement of the local search interface, prioritizing concise information for dining and retail over a broader set of points of interest.
For product and shopping searches, the product showcase feature has been updated from version two to version three, while the inline grid view has been disabled. This suggests ongoing adjustments to how e-commerce results are visually presented to the user.
The execution of mathematical and data-driven tasks on the web interface shows new activity. A configuration for graphable functions has been updated to enable version two, along with a flag for parameterized graphable functions. This implies that OpenAI is testing improved methods for rendering dynamic charts or mathematical graphs directly within the browser environment.
Following the enterprise focus observed in week 29, the configuration for external data connectors has evolved. SharePoint and Dropbox are now explicitly enabled in the connector list, while Google Drive has been toggled off in one specific configuration. This confirms the ongoing integration of corporate knowledge bases for grounded responses.
Regarding code generation and canvas interactions, a new label designated as "remix" has been added for shared code calls to action. This suggests that users may soon be able to duplicate and modify code blocks shared by others directly within the interface.
The advertising and commerce infrastructure continues to mature. The event tracking configuration previously named "bazaar" has been replaced by a new structure called "trailblazer". This system tracks events such as sign-ups, workspace creations, and plus subscriptions across specific international markets, including Australia, Brazil, Canada, India, Indonesia, the Philippines, and the United States.
Ad delivery mechanisms are also being adjusted. New parameters for multi-delivery and historical read-through have appeared but remain disabled, while a new ad placement strategy named "original turn" has been introduced. Additionally, the visibility timeout required before an ad card event is discarded on the web has been increased from 1.5 seconds to 3.5 seconds. This suggests that OpenAI is refining its viewability metrics to ensure users spend more time looking at an ad before it registers as a valid impression.
The system prompt instructing the model to answer user questions about displayed ads remains active. This confirms the continuity of the "Ask ChatGPT" feature for ads, where the model uses the ad's metadata to provide further details on products or services.
The image generation and moderation tests identified in week 29 remain active. Configurations related to speculative streaming, watermark detection, and the "ghostrider" workflow are still present, with minor adjustments to disk caching and prompt rewriting. This indicates that the optimization of image generation speed and safety is an ongoing priority.
User interface experiments regarding starter prompts should be followed next week. A configuration indicates a shift in the homepage prompt style from a chip layout to a list layout, alongside the activation of anonymous starter prompts for web users. This could change how new or logged-out users initiate their first search queries.
