Add default model population for AI Connector service providers by saikatsarkar056 · Pull Request #250506 · elastic/kibana

saikatsarkar056 · 2026-01-27T00:40:25Z

Summary

Users currently have to manually search for and enter model names when configuring AI connectors, which is error-prone and time-consuming. This change auto-populates the model field with recommended defaults, eliminating the need to look up model identifiers.

Release note

Improves AI connector setup by auto-populating the model field with recommended defaults, so users no longer need to search for and manually enter model identifiers.

 export const MAX_NUMBER_OF_ALLOCATIONS = 'max_number_of_allocations';
 export const CONTEXT_WINDOW_LENGTH = 'contextWindowLength';

+export const DEFAULT_MODELS: Partial<Record<ServiceProviderKeys, string>> = {


I think it makes more sense to add these default models to the INTERNAL_OVERRIDE_FIELDS. These are used in the mapProviderFields helper function where we already set a default_value if the field config has one. The model id default could be set there. It also keeps these internal changes that are service specific in one place and easier to track.

+ * @param providerService - the service provider identifier
+ * @returns the default model string if available, otherwise null
+ */
+function getDefaultModelValue(


A function like this should go in helpers.ts to keep this file size manageable.

Thanks so much for your work on this! 🙏 Left a couple of comments.

@saikatsarkar056 - gave this a test and there's an issue with trying to delete the model id to input something else. Just keeps resetting. Likely need to add some logic to add default value only once. Just checked some other providers and looks like this is a bug that's been around and unrelated to your changes. 🤔 Would be good to get that bug fixed prior to merging this as the modelId is very important for the user to be able to edit.
