# Model access, Builder checks and event diagnostics 2026-09-27 · Access > Features now use the models your account can see. Builder checks tool support before queuing jobs, and remote event diagnostics no longer include event content. Your model picker lists the models your account can use. A few features chose a model on their own and did not always check that list: the model a coding agent starts with in its workspace, the models an Ultracode run spreads its work across (and the cost estimate shown before it starts), the automatic model choice in chat, and the model a usage limit switches you to. All of them now choose from the same list as the picker. If a request names a model your account cannot use, ZeroLog answers with a "model not available" error. It does not quietly switch to a different model. If a model you used before is no longer in your picker, choose another one there. ## Website builder style choices Website projects now use the full curated style catalog in fresh installs and deployments. Each run has the same broader range of visual directions. ## Builder checks and event diagnostics Website Builder jobs now check whether the selected model supports tool use before they enter the queue. If it does not, the request is rejected before the job starts. Remote event diagnostics now keep basic status information without event content. Chat text is no longer copied into those logs. ## Website Builder engine selection Admin accounts can now select the early v2 builder for a website run. The selected engine stays with that run when it resumes. The new stages are still being built, so most currently use the existing builder steps. Customer accounts remain on the current builder by default.
