The following actions are now logged for AI Workflow entities and the AI Services user interface entity, which are are all versioned separately:

• Activated: When an artifact version is activated for the first time
• Cancelled: When an artifact version is cancelled
• Set as current: When a previously activated artifact version is set as the current version
• In review: When an artifact version is marked for review

These events appear in the System Log with the entity type corresponding to the entity type, enabling administrators to track and audit version management activities across the platform.

For more information, see Entities and Logged Actions for System Logs.

Bug Fixes

The following bugs are now fixed.

• The namespace field is now correctly populated in real-time inference curl command output for Scientific AI Workflows installed in the common namespace.
• When the AI Services page is under heavy load, AI Workflow installation statuses no longer appear as In Progress on the UI when they have actually successfully completed.

Deprecated Features

There are no deprecated features in this release. For more information about TDP deprecations, see Tetra Product Deprecation Notices.

Known and Possible Issues

The following are known limitations of TetraScience AI Services v1.1.1:

• Task Script README Parsing: The platform uses task script README files to determine input configurations. Parsing might be inconsistent due to varying README file formats.
• AI Agent Accuracy: AI-generated information cannot be guaranteed to be accurate. Agents may hallucinate or provide incorrect information.
• Databricks Workspace Mapping: Initially, one TDP organization maps to one Databricks workspace only.
• Analyst Policy Install Workflow UI Access: Users assigned a role with an Analyst policy can view, but not use, the Install Workflow button even though the policy doesn't allow them to install an AI workflow or run an inference. A fix for this issue is scheduled for a future AI Services UI release.

Upgrade Considerations

To upgrade to the latest AI Services version, see Update the AI Services UI version in the TetraScience AI Services User Guide (v1.1.x).

During the upgrade, there might be a brief downtime when users won't be able to access AI Services functionality.

After the upgrade, verify the following:

• Existing AI Workflow installations continue to function correctly
• Inference requests complete successfully with bearer token authentication
• GZIP-compressed files are processed correctly
• The AI Services UI displays correctly

v1.1.0

Release date: 21 January 2026

TetraScience has released TetraScience AI Services version 1.1.0. This release introduces support for Large Language Model (LLM) invocation through Databricks, common and client namespace support for Scientific AI Workflows, Tetra Data Platform (TDP) System Log integration, along with numerous bug fixes and user interface improvements.

Here are the details for what's new in TetraScience AI Services v1.1.0.

Prerequisites

TetraScience AI Services v1.1.0 requires the following:

• Tetra Data Platform (TDP) v4.4.1 or higher

New Functionality

New functionality includes features not previously available in TetraScience AI Services.

LLM Invocation Support through Databricks

TetraScience AI Services now supports invoking Large Language Models (LLMs) hosted on Databricks. LLM invocation capability is configurable as an API call within distinct Scientific AI Workflows and is available by default.

System Log Integration

AI Workflow operations are now logged in the TDP System Log, providing visibility into AI Services activities. The following event types are now available:

• AI Workflow installation (ai-workflow.install-request.v1)
• AI Workflow uninstall (ai-workflow.uninstall-request.v1)
• AI Workflow inference (ai-workflow.inference-request.v1)

For more information, see System Log.

Python LLM Wrapper for Tetra Data Apps and Task Scripts

To help simplify integration with AI Services from custom applications, a new Python wrapper allows Tetra Data Apps and Task Scripts to interact with online inference endpoints that serve LLMs.

common and client Namespace Support for AI Workflows

Scientific AI Workflows now support common (shared) and client namespaces, allowing organizations to differentiate between which AI Workflows are specific to their org and those that are shared. Support for private namespace AI Workflows is scheduled for a future AI Services release.

The backend correctly handles namespace for the following:

• Artifact differentiation and storage
• Installation and inference requests
• API responses and payload generation

Enhancements

Enhancements are modifications to existing functionality that improve performance or usability, but don't alter the function or intended use of the system.

Improved Inference Type Display

To help clarify what each inference endpoint type does, the previous Online and Offline inference endpoint types have been updated to the following in the AI Services UI:

• Real-Time Inference (formerly Online Inference): invokes the appropriate LLM, AI agent, or custom model to return real-time predictions from text-based inputs.
• Batch Inference (formerly Offline Inference): provides inputs through JSON files or specifies datasets for batch predictions and asynchronous processing.

Scientific AI Workflows also now correctly display only the supported inference types (Real-Time, Batch, or both) in the UI and API responses. Previously, workflows that only supported real-time inference incorrectly showed both batch and real-time endpoints.

Artifact Version Format Consistency

Version queries and responses now consistently use the vX.Y.Z format across all TetraScience AI Services endpoints, ensuring consistency with other TetraScience artifact management systems.

Admin Version Management

Administrators can now run the following actions on AI Services page versions:

• Setting a version as the default for all users
• Activating previously activated versions
• Canceling or disabling versions

For more information, see Update the AI Services UI Version in the TetraSciences AI Services User Guide (v1.1.x).

Improved Status Flow Logic

The artifact status flow logic has been hardened to correctly handle version rollback scenarios and status transitions between Approved, In Review, and Cancelled states.

Bug Fixes

The following bugs are now fixed.

Installation and Status Reporting Bug Fixes

• The API no longer shows Running status even after AI Workflow installation completes successfully on Databricks.
• Simultaneous AI Workflow installations no longer result in incorrect waiting statuses due to Databricks rate limiting.
• Failed installation requests no longer show Pending status instead of the correct error state.
• The AI Workflow installation response no longer shows the incorrect namespace (common) for client-specific AI Workflows.
• The List installations endpoint no longer returns malformed data when no active installations exist.

UI Bug Fixes

• The AI Services page now displays AI Services instead of AI Platform.
• The Install and Uninstall buttons no longer remain active after they're clicked.
• AI Workflow descriptions are no longer removed in the UI when new versions are published.
• The default AI Services page version now correctly changes for non-admin users after an admin activates a new version.
• Multiple modal popups no longer flash on screen during AI Workflow installation polling.
• Previously activated AI Services versions can now be set as the default version.
• Validation is now renamed to Actions in the UI for clarity.

Deprecated Features

There are no deprecated features in this release. For more information about TDP deprecations, see Tetra Product Deprecation Notices.

Known and Possible Issues

The following are known limitations of TetraScience AI Services v1.1.0:

• AI Workflow Installation Status Issue: When the AI Services page is under heavy load, AI Workflow installation statuses can appear as In Progress on the UI when they have actually successfully completed. As a workaround, customers can programmatically uninstall the Workflow and then reinstall it from the UI to ensure the status is correctly reported. A fix for this issue is scheduled for a future AI Services release.(Added on 8 December 2025)
• Task Script README Parsing: The platform uses task script README files to determine input configurations. Parsing might be inconsistent due to varying README file formats.
• AI Agent Accuracy: AI-generated information cannot be guaranteed to be accurate. Agents may hallucinate or provide incorrect information.
• Databricks Workspace Mapping: Initially, one TDP organization maps to one Databricks workspace only.
• Analyst Policy Install Workflow UI Access: Users assigned a role with an Analyst policy can view, but not use, the Install Workflow button even though the policy doesn't allow them to install an AI workflow or run an inference. A fix for this issue is scheduled for a future AI Services UI release.

Upgrade Considerations
