Fable Ultracode burns a 5-hour Max limit in 17 minutes by spawning 30 parallel researchers

teortaxesTex · x · 2026-11-12

User teortaxesTex reports that Fable Ultracode (high) burned through the entire 5-hour limit of a 5x Max plan in roughly 17 minutes, consuming 14% of the weekly quota — about 1% every 73 seconds.

The culprit: the model's first and only message declared "I'm launching 30 parallel researchers plus a completeness critic", and the massive parallel usage instantly drained the allowance. A screenshot confirms the session at 100% used with 14% of the weekly limit gone.

A striking data point on how quickly high-compute agent modes can eat through premium subscription quotas.
