OpenAI Prepares Hermes: New Feature to Revolutionize ChatGPT with App Store and Agent Workflows
November 28, 2025
These upgrades are part of OpenAI’s strategy to expand platform capabilities, reduce barriers for developers to bring custom agents and apps to ChatGPT, and may align with a December rollout pattern from last year.
Leaks from enthusiasts have indicated advanced testing and screenshots, suggesting a near-term launch is possible.
An Apps dashboard is in development to build, describe, preview, and publish apps for ChatGPT, initially limited to selected partners, with a broader Apps section planned.
The workflow builder is expected to gain image generation capabilities, potentially via a new image generation model, with integration planned into the workflow builder and a model upgrade around OpenAI’s December announcements.
Image generation support is slated to be added to the workflow builder, potentially tied to an upgraded model related to ChatGPT 4o and visible in the playground first.
OpenAI is developing a feature codenamed Hermes that would let developers publish agent workflows built with Agent Builder directly to ChatGPT via a workflow publish button that redirects to a unique URL on ChatGPT.
In addition to apps, the feature set includes third-party workflows and AI agents, each with its own URL, that users can integrate into their ChatGPT usage.
Developers will be able to publish third‑party apps directly in ChatGPT through an App Store–like interface, featuring screenshots, descriptions, and a Connect button for account linking.
While there is no official release date yet, testing activity indicates the features are in advanced stages, with speculation of a December unveiling akin to last year’s 12 Days of OpenAI event.
Speculation points to a December launch event in the spirit of OpenAI’s 12 Days of OpenAI format from 2024, though no official date has been announced.
Plans include a new Apps directory (potentially GPT Store v2) to let users browse and search for apps, with developers able to submit apps for review and publication later this year.
A preview shows an Apps menu in ChatGPT with app listings like Instacart, Gmail, and Expedia, including screenshots, descriptions, and a Connect button to link accounts.
Upcoming apps could include services such as Instacart, Gmail, and Expedia, highlighting the integration of external tools within the ChatGPT experience.
