Fuel iX Copilots — Week 33

This week brought a solid mix of new capabilities and reliability improvements. Highlights include expanded file upload support, and a handful of fixes that smooth out day-to-day friction — from more accurate Google Drive feedback to better handling of scheduled tasks and file status in chat.

Larger file uploads now supported: Files larger than 20MB can now be uploaded to the platform. The new upload flow includes built-in file size and type validation to keep transfers reliable.
Connections page now permanently available on profile pages: The connections experience is now a stable, consistent part of your profile — no longer behind a feature flag or inconsistently available.
Cleaner URL behavior for new conversations: Starting a new chat now keeps the /chats/new URL in place until you send your first message, making navigation more predictable.
Accurate feedback for Google Drive connection status: Fixed an issue where a Google Drive connection could fail silently while still showing a success message. You'll now see an accurate status when something goes wrong.
Regenerate button works reliably again: Fixed an issue where clicking the regenerate button more than once or twice would stop producing new responses.
Scheduled tasks now appear correctly in Custom Copilots: Fixed a bug where the task scheduling tool would silently disappear from a copilot's tool list even when it was enabled in settings.
Faster responses during background service disruptions: Resolved an issue where failures in a background telemetry service could delay AI responses by up to 32 seconds. Response delivery is no longer affected when that service has trouble.
More accurate file status in AI responses: AI agents now correctly report when an uploaded file is unsupported, failed, or cancelled — rather than repeatedly asking you to wait for processing that won't complete.
Knowledge bases created in chat are now properly tracked: Knowledge bases you create directly during a chat conversation are now correctly recognized as managed resources, keeping your knowledge base organization accurate and consistent.
System accounts removed from user selection lists: Internal service accounts no longer appear alongside real users in the org picker on Knowledge Base and Copilots pages, making it easier to find and assign the right people.
Cleaner user deletion — no more ghost accounts: Deleting a user now reliably removes all associated records in one go, with proper error reporting if any step fails. Previously, incomplete deletions could leave behind ghost accounts that caused authentication conflicts.
Fixed team data retrieval errors: Team records now correctly store their ID, resolving silent failures that caused every team lookup to return a validation error. Existing teams have been automatically updated — no action needed on your end.
Localization fix for database sync features: French users will now see dates and auto-sync notifications in French rather than English, resolving a display issue with "Last updated" dates and sync status messages.
More stable AI agent workflows with malformed tool calls: Agent runs no longer crash when an AI model produces empty or invalid tool-call arguments under heavy load. Bad arguments are handled gracefully so your workflow continues instead of failing.
Prompt caching across AI providers: Copilots now cache stable prompt content across Anthropic, OpenAI, and Gemini, reducing redundant processing and improving response efficiency in repeated or long-running conversations - still being rolled out.
