Errors

Same as GPT-Image 2. Note the official tier can be more sensitive to rate limits during peak hours; expect occasional 429 with a longer Retry-After.

When to use

Compliance / data-residency contracts requiring the stricter tier.
Audited workflows where the compliance tier is part of the spec.
For lower cost on identical model output, see GPT-Image 2.
For text-rendering edge cases, Nano Banana 2 is also strong.
