Grok 4.8 is taking longer than expected, Musk says

Elon Musk acknowledged the wait for Grok 4.8 in an X reply on 30 October. He said it had taken longer than expected and promised that the model would not disappoint. His emphasis was usefulness; he said benchmark optimisation was not the priority.

That pitch leaves a practical question: useful for which tasks? The post contains no demonstration or task-level results to answer it. Readers waiting to compare 4.8 with their current tools have a statement of intent, but no delivery schedule to plan around.
