Fulla vs Photoshop's generative fill
Last updated 10 November 2026
Fulla is a free Photoshop plugin that works like Photoshop’s own generative fill: select, describe, click Generate. The difference is who makes the images and how you pay for them. With Photoshop’s generative fill, Adobe makes them and you pay in generative credits from your plan. With Fulla, an AI service you choose makes them, and you pay that service per image.
The short answer
- Choose Fulla if you want to pay only for the images you make, see each image’s cost in dollars, use models Photoshop doesn’t offer, or get results up to 4K.
- Keep Photoshop’s own tool for quick fills with Firefly Fill & Expand, which costs 1 credit, or if your plan already gives you more credits than you use.
Side by side
Prices are for the same model on both sides, Nano Banana 2, unless the row says otherwise.

| Who makes the images | Adobe (Firefly, and partner models) | The AI service you connect: OpenRouter, Google or OpenAI |
| One fill, Nano Banana 2, 1K to 2K | 20 credits, about $0.10 at the smallest top-up | about $0.05, billed per image |
| One fill, Nano Banana 2, 4K | 30 credits, about $0.15 | about $0.12 |
| Paid up front | A monthly plan; credits left at the end of the month are lost | Nothing; a few dollars of credit, used image by image |
| How you see the cost | A credit estimate, if tooltips are on | In dollars, after every image |
| Models | Firefly, Nano Banana, FLUX | Nano Banana 2.1 and Pro, Qwen Image, GPT Image, and more |
| Output size | Firefly Image 5: 2K | Up to 4K, with models that offer it |
| Reference images | Yes, with some models | Yes, up to 8 per document |
| Where your photo goes | To Adobe | Straight to the AI service you chose |
Price
Photoshop’s generative fill is paid in generative credits. Each plan includes a number of credits per month, which don’t carry over, and more credits are sold as monthly add-ons. What a fill costs depends on the model and the size: 1 credit with Firefly Fill & Expand, 20 credits with Nano Banana 2, 40 with Nano Banana Pro. At the smallest add-on, $9.99 for 2,000 credits, a credit is worth half a cent, so a Nano Banana 2 fill is about $0.10. The full detail is in Photoshop generative credits, explained.
With Fulla, you pay the AI service per image, at its price. With Nano Banana 2.1, Fulla’s recommended model, we measured $0.048 for a 1K image and $0.063 for a 2K one on 10 November 2026. The panel shows the cost of every run; with OpenRouter, it is the exact amount billed.
Models
Photoshop offers Adobe’s Firefly models and a few partner models. Fulla offers a tested list from several services, and adds a model when it does better or costs less. See Models.
Resolution
Adobe’s Firefly Image 5 makes images up to 2K, about 4 megapixels; beyond that, Adobe offers a separate Generative Upscale, paid in credits. Fulla’s Auto resolution asks for about twice the size of your selection, up to 4K when the model offers it. See Resolution.
Privacy
With Photoshop’s generative fill, your image goes to Adobe. With Fulla, it goes from Photoshop straight to the AI service you chose: there is no Fulla server. See Privacy and security.
