What does creativity 9 mean?

It allows the most new detail within Bloom’s creativity range. At 1 the interpretation stays closest to the input; the default is 3.

Can I leave the prompt empty?

Yes. Our portrait tests used no prompt at all. A description is optional guidance for the additional detail.

Does Bloom Realism cost more than Bloom 2?

At the same resolution tier, the presets have the same per-image price. Neither creativity nor output format changes the charge.

Introduction

Creative enlargement

Bloom adds a creative reconstruction pass while increasing image size. bloom_2 is selected when you omit preset.

Bloom request

Set resolution to 2k, 4k or 8k; the default is 4k. creativity defaults to 3 and prompt is optional.

Creative boundaries

Check new faces and textures in the downloaded JPEG or PNG. bloom_realism rejects creativity above 4 even though the other two models accept up to 9.

Key features & highlights

Bloom 2 gives the face a more textured finish

At 2K and creativity 3 without a prompt, Bloom 2 reconstructed eyes, stubble and visible skin texture from our blurred portrait. Added detail is an interpretation of the face, not proof of what the camera captured.

Compare the same face across the Bloom presets

Left to right: Bloom 2, Bloom Realism, Bloom. Bloom 2 looks more textured; Realism gives a clearer face with slight changes in likeness; original Bloom stays softer in this trial. The three runs took about 86, 134 and 273 seconds respectively.

Parameter	Required	Description
`image_url`	Yes	The existing picture whose composition Bloom will expand and reinterpret. at least 1 characters

`prompt`	No	Optional description of the scene or desired finish to guide Bloom’s new details. at most 2000 characters

Creative boundaries

Bloom deliberately invents detail and can change faces, textures or small objects. Use it when that creative change is welcome. creativity must be an integer from 1–9, and only 1–4 with bloom_realism; larger Realism values are rejected. Timing varies by image and preset.
