Issue: Browser tab crashes when loading a larger model on iOS 26 (Safari)

[internalbuilds]

Description:
On iOS 26 using Safari, I was able to successfully run prompts with the model SmolLM2-135M-Instruct-q0f16-MLC. However, this model didn’t produce the quality of results I needed, so I attempted to switch to Qwen2.5-3B-Instruct-q4f16_1.

The larger model does begin downloading, but once the download completes, Safari terminates the tab with a generic “A problem occurred with this webpage” message. Unfortunately, Safari provides no further logs or diagnostic details, so I’m unable to include any meaningful crash information.

Expected behavior:
The page should load and initialize the larger model without causing Safari to kill the tab.

Actual behavior:
Safari closes the tab immediately after the model finishes downloading.

Additional info:

Device: iOS 26

Browser: Safari

The smaller model works without issues

No visible console logs or error output before the crash
