New Features & Enhancements

Feature focus: API Call History

The API Call History records all of the API Calls made to Spark, enabling audit, review, and analysis of past executions. For this month’s release we’ve made some often requested enhancements and more for the API Call History:

  • API Calls sometimes may lead to errors or warnings due to use of default values, invalid input values, or even calculation errors. Identify API Calls that returned errors or warnings during execution using the ⚠️ ⛔ symbols. These API calls can also be filtered and downloaded for further examination. Note this will only apply to new API calls post this release.

  • Review table inputs and outputs with ease using the Download as Excel file (Expanded tables). Table inputs and outputs are displayed on separate worksheets which makes it easy to analyze complex call history for models with complicated table structures.

  • API Call History now will record if the excel_file parameter is provided in an API Call.

  • Addressed a bug with filtering the API Call History for call_purpose and source_system.

Download Service Update

We’ve improved the design of the Download service feature to make the different options more clear! Most users likely will want to download the Original workbook but can use the Coherent Assistant option if you would like to explore the file in the add-in right away.

Make AI integrations easier

We’ve been looking at how we can make integrating an application to Spark easier. In this release we have made some enhancements to make AI consumption of Spark services easier:

  • API Tester Swagger documentation can be accessed without authentication if the Spark service is made public.

  • API Tester automatically generated API documentation now also includes information about the Validation API. The Validation API includes details about single value inputs which can facilitate the development of a UX around a Spark service.

Other Notable enhancements

  • The Testing Center Systematic test case generation now includes an option to Clear variations in order to reset the number of variations back to 1. This makes it easier to build up your custom variations if there are too many variations created by default.

  • The Event viewer shows all the recent activities on an environment. When initially released, it defaulted to filtering one folder at a time. We have updated the feature such that viewing events across all folders is now the default.

  • Further UI updates to improve the experience for users with limited permissions.

  • Performance improvements in the Coherent Assistant Testbeds functionality.

  • Security patch updates to address vulnerabilities, ensuring enhanced protection and stability for the system.
