Sep 1, 2025September 2025 — Cardstack/boxel delivered LLM Model Configuration and UI Selection. The feature adds new card definitions for LLM environments and model configurations, enabling specification of available LLM models, and a UI that lists and allows selection from defined models. Acceptance tests were updated to validate creation and usage of the new configurations. A targeted test was introduced to ensure the model list is specified in a card, driving early validation and reducing misconfigurations. Overall, this work strengthens configurability, accelerates experimentation, and improves reliability for LLM integrations.
