Token Plan prohibits application backends, automated scripts, and non-interactive batch workloads

The qwen3.8-max-preview ID now routes to production qwen3.8-max, while the individual Token Plan terms still restrict automated scripts, application backends, and non-interactive batch workloads.

Grok 4.5xAIWatchProduct experienceUsage limits

A new report says SuperGrok 4.5 hit its weekly allowance after roughly two hours of coding

In a July 14 r/grok thread, one user said a routine JavaScript coding session through Grok CLI reached the SuperGrok 4.5 weekly allowance in roughly two hours. The same reply praised speed but reported needing more prompts and questioned plan transparency. This single public thread concerns the consumer subscription/Grok CLI experience, not xAI API limits or a representative sample.
