Astria vs Pablo: Nano Banana Photoshop Plugin Guide
Pablo and the Astria Nano Banana plugin for Photoshop are the two closest products in this category. Both offer a one-time plugin licence with usage billed separately. Both accept your own Google key. Both send a Photoshop selection to Nano Banana, Seedream or GPT Image and bring the result back as a layer. Astria is the overall winner for a Photoshop professional who wants the panel to stay current without maintenance. New models appear from the Astria platform with no plugin update. Every result lands as a Smart Object at the model's full returned resolution, and the same key runs Astria workspaces and the API for jobs that never open Photoshop. Pablo's genuine strengths are published pass-through rates and agency licensing.
How we evaluated Astria and Pablo
The reader is a retoucher, photographer, designer, agency or ecommerce studio that lives in Photoshop and wants current generative models inside a live document, without a browser round trip. We scored both plugins on six criteria: model roster and update speed; returned resolution, layer type and mask handling; editing workflow; billing flexibility and bring-your-own-key support; maintenance and longevity; and production beyond the document. We reviewed public product, pricing, terms and marketplace pages on 13 September 2026. No output-quality benchmark was run.
Quick verdict: Astria vs Pablo
| Decision factor | Pablo | Astria | Winner |
|---|---|---|---|
| Models in the panel today | Nano Banana, Nano Banana 2, Nano Banana Pro, Seedream 4.0 and 4.5, GPT Image 1.5, 2 and 2.5 (pricing page and Exchange notes) | GPT Image 2 (mask-aware, 1K/2K/4K), Nano Banana 2, Nano Banana Pro, Seedream 5 Pro, Seedream 5, Flux 2 Pro; GPT Image 2.5 Sunburst and Flare and Muse Image already on the platform the panel reads from | Astria for current-generation Seedream, Flux and mask-aware GPT Image |
| New-model lead time | Tied to plugin versions: GPT Image 2.5 arrived in version 0.7.46 on 11 September 2026, three days after OpenAI's release; the user must update | Model list served by the Astria platform; a model added to Astria appears in the panel with no plugin update or re-download | Astria |
| Returned resolution and layer type | 4K generation advertised for Nano Banana Pro; GPT Image priced at 1K; returned pixel size and layer type not publicly verified | Up to 4K per generation; each result is a Smart Object holding the model's full returned resolution | Astria |
| Selection-to-layer workflow | Inpainting and "add and replace objects" advertised; result returns as a layer; selection handling not detailed publicly | Marquee, lasso, brush or colour range; prompt; generate. Mask-aware models read the selection directly; result lands as a new layer | Astria |
| Reference-driven edits | Multi-reference images; one public Exchange review asks for more than four; behaviour with a selection not detailed publicly | References dropped into the panel act as visual instructions, alongside a selection that mask-aware models read directly | Astria for references combined with a mask-aware selection |
| Billing paths | Pablo credits at pass-through rates, or your own Google or Replicate key | Astria key for pay-as-you-go across every model, or your own Google AI Studio key; the same balance drives Astria workspaces and the API | Astria for a balance that is not stranded in one plugin |
| Commercial model | Individual and agency licences, hosted usage with published pass-through rates, or supported provider keys; see Pablo pricing | One-time plugin licence, hosted pay-as-you-go, or a Google key for Gemini models; see Astria pricing | Depends on seat count and model mix |
| Production beyond the document | Plugin plus an account dashboard for licences and credits | Same key runs Astria workspaces, templates and the API for collection-scale work | Astria |
| Maintenance and longevity | On Exchange since 4 December 2025; version 0.7.46 in September 2026; dated blog; support desk | 16,000 sales and 187 ratings (first-party); CCX/UXP rebuild in 2026; dated changelog; one surface of the Astria platform | Astria |
| Best fit | An agency buying seats in bulk that wants published pass-through rates and Nano Banana, Seedream 4.x and GPT Image in Photoshop | A retoucher, photographer or studio that wants every current model as a full-resolution Smart Object, with a production route for the rest of the catalogue | Astria |
| Overall | The closest rival, with public rates and agency licensing | Zero-day models, Smart Objects at original resolution, and a platform behind the panel | Astria |

Pablo: a hosted-credit panel with published rates
Pablo is a UXP plugin for Photoshop 26.0.0 or higher, made in Amsterdam and listed on Adobe Exchange on 4 December 2025. Its pricing page lists Nano Banana, Nano Banana 2, Nano Banana Pro, Seedream 4.0 and 4.5, and GPT Image 1.5, 2 and 2.5. The Exchange listing describes multi-reference images, 4K generation and "add and replace objects". Its note for version 0.7.46, updated 11 September 2026, adds GPT Image 2.5 Flare and Sunburst.
Commercially, Pablo publishes what many rivals do not: individual and agency licensing plus hosted rates organized by model and resolution, which it says carry no markup over the provider rate. You can also bring a Google or Replicate key. Check Pablo's pricing page for current licence, usage, refund, and seat terms.
Two things to read before paying. Pablo's terms say prepaid credits expire 24 months after purchase unless otherwise specified at checkout, and one public Exchange review alleges a 90-day window on a balance. Check the expiry shown when you top up. Separately, the public pages do not say what layer type a result lands as, or what pixel dimensions come back when a 4K generation is placed into a small selection.
Astria: the panel is one surface of a platform
The Astria Nano Banana plugin for Photoshop is a CCX/UXP panel for Photoshop 2025 (version 26 and above) on macOS and Windows. The panel carries GPT Image 2 (mask-aware, at 1K, 2K or 4K), Nano Banana 2, Nano Banana Pro, Seedream 5 Pro, Seedream 5, and Flux 2 Pro. Flux Kontext was retired in favour of these. The landing page also lists GPT Image 2.5 Sunburst and Flare and Muse Image as available now on the platform.
That last sentence is the first headline. The panel's model list is served by the Astria platform, so a model added to Astria appears in the panel the day it launches, without a plugin update or re-download.
The workflow is three steps. Select with the marquee, lasso, brush or colour range. Prompt in short, specific language. Generate, and the result lands as a new layer. Mask-aware models read the selection directly. Reference images dropped into the panel act as visual instructions. The model is chosen per task from one dropdown, and keys are switched inside the panel.
The third headline is what that layer is. Each generation is placed as a Smart Object holding the model's full returned resolution. A 4K result placed into a small selection still carries the 4K pixels, so it can be re-transformed, masked and re-edited later without resampling.
The Astria plugin uses a one-time licence with usage billed separately. One Astria key authenticates every hosted model, and Astria abstracts the Google, OpenAI, fal and ByteDance APIs so quota, authentication and retries stay invisible. Or paste a Google AI Studio key and run Gemini models against your own Google account. Current terms are on the Astria pricing page. No GPU is needed.
