- Can I log in, pay and generate directly on this page?
- Yes. Press Generate while signed out and the account dialog opens in place. After login the studio shows your current credit balance and this run’s exact cost. If your balance or plan is insufficient, it opens the pricing and upgrade flow; after payment you return to this page and generate through the same form.
- What is GPT Image 2.5?
- GPT Image 2.5 is OpenAI’s current image model, the successor to GPT Image 2. Soku runs its flare tier — OpenAI’s general-purpose tier — through fal.ai, on both the text-to-image and the reference-guided edit route.
- How do I get the text in the image to come out right?
- Quote it. Write the words you want using a phrase like "the headline reads exactly:" followed by the copy, and give each string its own line in the prompt. Describing the text ("a bold headline about travel") leaves the model to invent it; quoting it gives the model something to render.
- What is the difference between the flare and sunburst tiers?
- They are the same price. Flare is OpenAI’s default for most work and is what this page runs: fast, with transparent-background support and strong handling of complex layouts. Sunburst trades generation time for extra fidelity on intricate detail, and is aimed at premium one-off visual work rather than the iteration loop this page is built for.
- Does GPT Image 2.5 support transparent backgrounds?
- Yes, on both routes. The badge in the gallery above was generated with a transparent background rather than cut out afterwards, which is why its enamel edge and brass rim stay clean when composited.
- How many reference images can the edit route take?
- Up to four. Put the image the edit is about first — the route treats the first reference as the primary one — and use the others for the product, subject or style you want carried in.
- Should I use GPT Image 2.5 or Nano Banana 2?
- Use GPT Image 2.5 when a wrong character makes the image unusable: posters with headlines, menus, price badges, UI mockups, labelled diagrams. Use Nano Banana 2 when you need many images, want a wider set of aspect ratios, or the words are not what the image is carrying — it costs roughly 2.6x less per image.
- What happens if a paid generation fails?
- The generation service records the deduction before submit so ownership and polling remain safe, but a failed provider job is refunded automatically. The studio reports the failure instead of leaving the credits spent with no output.
