Claude 4 models are unusable

[king728]

Litterally can't get a response from either model without getting TEMPORARILY_UNAVAILABLE error. Is there quota for these models can't find it anywhere in the docs.

Hello @king728 ,

Claude 4 models are currently encountering issues related to availability, specifically resulting in the TEMPORARILY_UNAVAILABLE error. This situation appears from capacity constraints and throttling rather than an explicit quota limit.

Claude 4 Sonnet is facing significant capacity challenges, which has led to high demand exceeding available resources which may improve as more resources come online by the end of July.

If you are experiencing regular issues with Claude 4, it could be helpful to switch to Claude 3.7, which seems to have slightly more available capacity at this time.
