Browse and compare models

Open a model file on the Files page of Azure Repos and select the Preview tab. The preview lists the components of the model and draws its schematic. Click a component in the list or a node on the schematic to see its values. You can’t change the model from the preview.

The preview of model.json: the components of the model in a list on the left, the schematic in the centre with Blackwater Reservoir selected, and its values on the right, such as its type, Storage, and its maximum volume, 16000.The preview of model.json: the components of the model in a list on the left, the schematic in the centre with Blackwater Reservoir selected, and its values on the right, such as its type, Storage, and its maximum volume, 16000.

To see what changed between any two versions of a repository, such as a release tag and main, select Compare versions on the Model reviews page. Pick the repository, then type a branch, a tag or a commit in From and To. The changes open in the same three panes as a pull request. Every difference between the two versions is listed, including changes made to From after the two split. A comparison has no pull request, so you can’t comment on it, approve it or tick its changes.

The Compare two versions form: the drought-plan-2027 repository, release-2025 in From, main in To, and the Compare button.The Compare two versions form: the drought-plan-2027 repository, release-2025 in From, main in To, and the Compare button.
