Most of the transformers.js workloads with Wasm backend (7 out of 9 workloads) time out in Safari 26.2. Some of these workloads previously tested in older version of Safari (in Nov 2025) and they worked fine. I reverted to the exact Git commit used during the November tests, the workloads now timeout in the current Safari version. So my conclusion is that the issue is specific to the latest version of Safari and not the benchmark itself.
Filing this issue to track the more investigation and determine if a bug report needs to be escalated to the WebKit team.
