OpenArt vs Elyumfor Nano Banana 2
Same Google model, but Elyum bills only kept Nano Banana 2 takes while OpenArt charges credits on every render, including failed ones in reviews.
Nano Banana 2 is Google's fast stills model. It holds a face and a product label across edits, so it gets used for catalog crops and reference-matched headshots. Talk to it like a photographer: name the lens, the key light, and what must stay put. It does text-to-image and image editing. It will not output video.
The weights are the same. The bill is not. OpenArt sells Nano Banana 2 inside a credit subscription that starts at $13/mo on Starter. OpenArt's pricing page does not list a per-image rate for this model. Elyum prices the same model by resolution on the Nano Banana 2 page, and every render is a free preview you KEEP or KILL. OpenArt also ships Director, One-Click Story, and consistent-character slots by plan. Elyum has no timeline editor, no stock footage, and no talking-head avatars of its own.
OpenArt is the broader tab if you want 100+ models and story tools in one place. Elyum is the keep-or-kill meter for this model, from Free (up to 150 credits once (our algorithm may grant them)) to Ultra at $69/mo. Compare studio-wide plans on Elyum pricing or the OpenArt alternative when you are picking a home, not a single model.
Nano Banana 2 on OpenArt
OpenArt lists Nano Banana 2 among supported models in its 2026 generators post. It does not publish a Nano Banana 2 credit price on the official pricing page. Third-party tables put a standard 1024x1024 image at 1 credit and a 2048x2048 at 4 credits. Treat those as generic image rates, not a confirmed quote for this model. Starter is $13/mo for 4,000 credits, watermark-free, without commercial use. Plus at $27/mo adds commercial rights. Which plan first unlocks Nano Banana 2 is not stated.
OpenArt has no published automatic refund for a failed or ugly Nano Banana 2 render. Trustpilot reviews of OpenArt report credits burned on failed renders with no clear refund path. Base subscription credits are reported by a third-party aggregator to expire monthly (not confirmed on openart.ai). OpenArt offers an MCP server. No separate public developer API price appeared on the official pricing page.
Nano Banana 2 on Elyum
On Elyum, Nano Banana 2 runs as text-to-image and image editing at three sizes: 1K at 3 credits ($0.03) per render, 2K at 4.5 credits ($0.04), and 4K at 6 credits ($0.06). Ultra ($69/mo) includes fair-use unlimited image generation on selected image models, including this one. Start on Free (up to 150 credits once (our algorithm may grant them), no card) or Plus at $9/mo. Kept files download at full quality with no watermark, and commercial use is included.
Every take comes back as a free preview. KEEP is the only moment credits leave the balance. KILL refunds the take in full. A failed generation is never charged. The Free plan meters kills at one a month; Plus, Pro, and Ultra kill freely. Agents can drive the same balance through Elyum's MCP server or the REST API.

|---|---|---|
| One 1K render you keep | Not published for Nano Banana 2 (generic 1024 image: 1 credit) | 3 credits ($0.03) |
| Ten 1K renders, keep three | Not published; unused takes still spend credits per reviews | 3 credits ($0.03) |
| A failed generation | No published refund; reviews say credits still consume | Never charged |
| Monthly plan to reach the model | Unlocking plan not published; Starter is $13/mo | Free (up to 150 credits once (our algorithm may grant them)); Ultra $69/mo fair-use unlimited |
| Watermark on a paid download | None from Starter up (official paid watermark: false) | None on kept takes |

Where the two differ
OpenArt does not publish a Nano Banana 2 credit price. Generic image rows on third-party tables are 1 credit at 1024 and 4 at 2048. Elyum lists 1K, 2K, and 4K with 3 credits ($0.03), 4.5 credits ($0.04), and 6 credits ($0.06).
Elyum refunds a KILL in full and never charges a failed job. Paid plans kill without a cap; Free allows one kill a month. OpenArt has no published automatic refund. Trustpilot reviews name credit loss on failed renders as a common complaint.
Elyum publishes 1K, 2K, and 4K for this model. A third-party OpenArt breakdown lists image tiers up to 4096x4096 at 8 credits; that ceiling was not confirmed on openart.ai/pricing, and it is not a Nano Banana 2-specific figure.
OpenArt is stronger here. You get Director, One-Click Story, and consistent-character slots from 13 on Starter to 353 on Wonder. Elyum is a generate-and-keep studio. We do not ship a timeline editor, stock footage, or talking-head avatars.
Elyum Ultra ($69/mo) includes fair-use unlimited image generation on selected image models, including Nano Banana 2. OpenArt's Wonder plan ($175/mo) advertises Unlimited Creation only for MiniMax H3 Max, not for this model.
OpenArt's pricing page lists commercial use on Plus, Pro, and Wonder, and excludes it on Starter and the free tier. Paid OpenArt output is watermark-free from Starter. Elyum includes commercial use and no watermark on kept takes. OpenArt base credits are reported to expire monthly (checkthat.ai, unconfirmed on-site).
Pick OpenArt when
- You want 100+ image, video, and audio models under one credit subscription, not a single-model meter.
- You already rely on Director, One-Click Story, or Character Creator (13 to 353 slots by plan).
- You want watermark-free files from the $13/mo Starter plan, even without commercial rights.
- You need 8 to 32 parallel generations and OpenArt's MCP server inside an existing OpenArt workflow.
Pick Elyum when
- You iterate hard: previews are free, KEEP is the only charge, and a KILL refunds the take.
- You want listed Nano Banana 2 prices at 1K, 2K, and 4K, plus fair-use unlimited on Ultra ($69/mo).
- You need commercial, watermark-free keeps from Free (up to 150 credits once (our algorithm may grant them)) or Plus at $9/mo.
- You want MCP plus a documented REST API, and you do not need Director or a community feed.
Nano Banana 2 in three styles, rendered on Elyum
Getting the most out of Nano Banana 2
- Lock identity with a still reference and say what must not change (face, logo, label type). Then change only wardrobe, backdrop, or lighting. Contradictory same-person-but-new-face prompts smear features.
- Write camera language: 85mm, f/2.8, three-quarter view, soft key from camera left. Nano Banana 2 follows lens and light more reliably than stacked style names.
- Put the aspect ratio in the prompt (1:1, 4:5, 16:9, 9:16). For a pack shot, state product scale and a sweep background so it does not invent a lifestyle set.
- On edits, name the region and the action (replace the sky, remove the cup on the right). Do not re-describe the whole frame or it will restyle the subject you meant to keep.
- Quote on-image text in quotation marks and give a placement. Keep lettering short. Long signage still fails.
- Do not use video verbs (pan, dolly, 24fps) or a clip length. Nano Banana 2 is stills only. Motion needs a different model.
