Google Antigravity - HTTP 503 MODEL_CAPACITY_EXHAUSTED on Ultra plan for 1 week

Hi Google Antigravity team,

I have been experiencing the same error for about 1 week while using Google Antigravity. I am currently on the Ultra plan, but I keep getting a 503 error saying there is no capacity available for the model.

Here is the latest error:

Trajectory ID: ae788c49-467e-4c19-8d4c-ebc10055
Error: HTTP 503 Service Unavailable
TraceID: 0x2d959a8d98299
X-Cloudaicompanion-Trace-Id: 2d959a8d982999ab
Model: claude-opus-4-6-thinking
Reason: MODEL_CAPACITY_EXHAUSTED
Message: No capacity available for model claude-opus-4-6-thinking on the server
Status: UNAVAILABLE

I have already tried restarting Antigravity, starting new sessions, signing out and back in, and changing accounts, but the issue still continues. Since I am paying for the Ultra plan, I would like to know if this is a general capacity issue, a routing issue, or something related to my account.

Could someone please help me check what is happening with my account or explain what I should do to fix this?

Thank you.

Hola equipo de Google Antigravity,

Llevo aproximadamente 1 semana con el mismo problema usando Google Antigravity. Actualmente tengo el plan Ultra, pero constantemente me aparece un error 503 indicando que no hay capacidad disponible para el modelo.

Este es el último error:

Trajectory ID: ae788c49-467e-4c19-8d4c-ebc100550
Error: HTTP 503 Service Unavailable
TraceID: 0x2d959a8d98299
X-Cloudaicompanion-Trace-Id: 2d959a8d982999ab
Model: claude-opus-4-6-thinking
Reason: MODEL_CAPACITY_EXHAUSTED
Message: No capacity available for model claude-opus-4-6-thinking on the server
Status: UNAVAILABLE

Ya intenté reiniciar Antigravity, abrir sesiones nuevas, cerrar sesión y volver a iniciar sesión, e incluso cambiar de cuenta, pero el problema continúa. Como estoy pagando el plan Ultra, quisiera saber si esto es un problema general de capacidad, un problema de routing o algo relacionado con mi cuenta.

¿Podrían ayudarme a revisar qué está ocurriendo con mi cuenta o indicarme qué debo hacer para solucionarlo?

Gracias.
