validateModels function

Future<List<AiModelCheck>> validateModels(AiProvider provider, List<String> models)

Validates models against provider by sending a minimal, tool-free request per model — confirming the API key works and each model id is accepted. Errors are captured per model rather than thrown, so one bad model does not hide the others.

Pure Dart (no dart:io): the caller injects the provider, so this is unit-testable with a fake.

Implementation

Future<List<AiModelCheck>> validateModels(
  AiProvider provider,
  List<String> models,
) async {
  final results = <AiModelCheck>[];
  for (final model in models) {
    final sw = Stopwatch()..start();
    try {
      await provider.chat(
        messages: const [AiMessage.user('ping')],
        tools: const [],
        model: model,
      );
      sw.stop();
      results.add(
        AiModelCheck(model: model, ok: true, latencyMs: sw.elapsedMilliseconds),
      );
    } on AiProviderException catch (e) {
      sw.stop();
      results.add(AiModelCheck(model: model, ok: false, error: e.message));
    } catch (e) {
      sw.stop();
      results.add(AiModelCheck(model: model, ok: false, error: '$e'));
    }
  }
  return results;
}
