Strengths

Reasoning-led generation

Built on the GPT-5.4 stack, it reasons about the brief before rendering, which helps on prompts with constraints, counts, and relationships.

Nuanced brief handling

Long creative directions — mood, lens, materials, what to avoid — survive into the final image instead of being averaged away.

Editing supported

Send a reference image to edit or restyle while keeping the original composition.

From $0.07 per image

Flagship-class output at the same per-image price band as GPT Image 2, billed from your prepaid balance.

GPT-5.4 Image 2 API — reasoning-led image generation

GPT-5.4 Image 2 is the image generation model built on OpenAI's GPT-5.4 line. Because it reasons over the brief before rendering, it holds onto constraints — object counts, spatial relations, explicit exclusions — that purely diffusion-driven models tend to lose.

On YepAPI it is one `POST /v1/media/queue` call away at about $0.07 per image, with the same key, envelope, and billing as every other model.
