OpenAI goes down, everyone rushes over to Claude. Claude promptly chokes under the pressure. Everyone panics and runs to Grok, and Grok immediately pulls the plug. We are officially witnessing the Great AI Migration of 2026, and all we have to show for it is a digital graveyard of 404 responses.

Which is exactly why I am running Qwen 3.8 35B locally on my MacBook Pro M5 with 128GB of unified memory.

I am only seeing one session work, but all other sessions are not working or proceeding. So I can only work in one chat session.
