Claude 4 sonnet failing too much

Describe the Bug

I am currrently using the Claude 4 Sonnet model with usage based pricing in the Pro plan and without max mode.

The model used to be great, but in the past few days it is very slow at times and failing too much, giving redundancies, not following the exact commands, etc..

Steps to Reproduce

Start using it, give various commands, some complex and the bug starts.

Expected Behavior

Work correctly.

Operating System
