New Features

  1. GPT-5 has been added to our system:
    1. Available to all users who have access to model selector dropdown.
    2. Available with Agent Capabilities: Optimal Choice, Highest Relevance, Complex Reasoning
    3. Available with Agentic Actions: Drive Conversions, Website Awareness, Doc Analyst
    4. This is the basic GPT-5 and does not have reasoning capabilities - these options will be added later.
    5. GPT-4o remains the default model for the time being, as we continue GPT-5 testing.
  2. Document Analyst Agentic Action is now available for our Premium users. Additionally, we have expanded support for additional filetypes: PDF, TXT, DOC, DOCX, ODT, JPG, JPEG, PNG and WEBP.
  3. We have added support for API key per-agent granulation, and users can now:
    1. Create an API key that pertains just to a selected agent(s).
    2. Such API keys can't create new agents or do any account-level actions, like view user profile.
    3. Unlike global API keys, these granulated keys can only work within one team!
  4. In-chat avatar controls - Our premium users can now enable or disable both agent’s and user’s avatar within the chat interface.

Improvements

  1. The in-chat text input field now gets automatically in focus on any click inside the agent’s window.
  2. The in-chat text input field now gets automatically in focus as soon as the agent's response finishes streaming.
  3. The in-chat text input field now gets automatically in focus as soon as the agent window is opened for Live Chat, Website Copilot and Instant Viewer deployments.
  4. Links & Sources Analytics page now supports URL parameters for selected filters, enabling easier sharing.
  5. A border has been added to the in-chat agent avatar, when there is no active conversation.

API & MCP

  1. Fixed the issue where the endpoint https://app.customgpt.ai/api/v1/projects/{projectId}/sources/{sourceId} in API Reference call example was throwing errors.

Bug Fixes

  1. Fixed the issue with the Starter Question styling not being correctly applied.
  2. Fixed the issue where short timeout was causing crawling issues with some slower websites.
  3. Fixed the issue where case-sensitive URLs would not get crawled correctly.
  4. Notifications are now correctly cleared by clicking on them.
  5. Fixed the issue where on the Ask page, if no conversation is active, the agent's avatar wasn’t being displayed.
  6. Fixed the rare issue where incorrect Starter Questions format blocked the agent's UI.
  7. Improved slow loading on Actions page.
