Release notes

The Decisions API is now generally available with gpt-6-luna. Cache shared input across requests for prompt-cache discounts, include images in individual question instructions, and pass structured data directly with input_json. Each request now supports up to 400 questions, increased from 200 in public beta.

Enterprise workspace members can share their profiles with coworkers, including activity and Sites they choose to showcase. Workspace owners control whether profiles and activity are available and whether profiles are visible only to their owners or to other workspace members.

Shared Enterprise profiles are limited to members of the same workspace. Adding a Site to a profile does not change who can access that Site. Shared profiles do not show conversation titles or content.

You can now choose which service tiers projects can use in Platform settings. Organization settings can restrict service tiers for all projects.

In addition to Workspace settings in ChatGPT, workspace owners and admins can manage members and available Business workspace controls in Admin Console. Select your Business workspace. For some workspaces, selecting Workspace settings automatically opens Admin Console.

Your workspace role and plan permissions still apply. Using Admin Console does not add Enterprise-only features or change who can manage paid seats.

You can now choose 12-hour prompt caching in the API. 12-hour prompt caching keeps shared instructions, tools, and context cached longer to benefit from lower cached-input pricing, even when requests are hours apart. 12-hour cache writes cost 2.5x the input token price.
