Family: GPT (OpenAI) Model ID: gpt-image-2-official Capability: 1024² – 4096² · photorealism · prompt-following Pricing: per image, official tier (live rate) GPT-Image 2 Official is a higher compliance tier of GPT-Image 2 — same model weights and output as GPT-Image 2. Use this variant when compliance, data-residency contracts, or audit requirements call for the stricter tier. The price tier reflects the premium.

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.
