Runway vs Elyumfor Nano Banana Pro
The deciding difference is that Runway charges 4 credits when a Nano Banana image completes, while Elyum returns a free preview and bills only if you keep it.

Nano Banana Pro is Google's 4K stills model, the one you reach for when the frame has to carry readable type. Posters, UI chrome, product labels, slide diagrams. The Nano Banana Pro page calls it best 4K images, near-perfect text. It is an image model (text-to-image and image editing), not a video generator. If your brief is key art with a headline that must be spelled right, this is the model.
On Runway the model is listed as gemini_image3_pro (Nano Banana Pro) in the developer docs. Example costs put Nano Banana image generation at 4 credits per image. Credits return only on a hard generation error. A finished-but-ugly frame keeps the charge. Standard is $15/mo with 625 credits and no watermarks. Free is 125 one-time credits and a limited model set. On Elyum, 1 credit = $0.01. Plans are Free (up to 150 credits once (our algorithm may grant them)), Plus $9/mo, Pro $29/mo, Ultra $69/mo. Every render is a free preview. KEEP pays. KILL refunds. Failed generations are never charged. See Elyum pricing or the Runway alternative page for the rest of the catalog.
Runway is the better house if you need Aleph in-context video edits, brand kits, custom voice clones, HDR/ProRes, or 4K upscaling bundled with the same login. Elyum does not have a timeline editor, stock footage, avatars, a mobile app, team seats, or a community feed. Commercial-use terms on Runway were not independently verified from official ToS in the research pass. Free-tier watermark status on Runway is unpublished.
Nano Banana Pro on Runway
Runway lists the model as gemini_image3_pro (Nano Banana Pro) in its developer model guide. Runway's pricing page lists Standard at $15/mo (625 credits), Pro at $35/mo (2,250), and Max at $95/mo (9,500). Standard includes all AI video and image models. Free is 125 one-time credits and a limited model set. Whether Nano Banana Pro is in that free set is not published.
Example costs list Nano Banana image generation at 4 credits per image. A hard generation error returns credits. A completed image that is low-quality, off-prompt, or unwanted does not. Paid plans have no watermarks. Free-tier watermark status is not published. 4K upscaling is included on Standard and unlimited on Pro and Max. Cents per credit are not published as a flat rate. The same examples price a 60-credit Gen-4.5 clip at about $0.60 on the Standard blended rate. Monthly credits reset on Standard and Pro. Max allows one month of rollover. Top-up credits (blocks from 1,000) do not expire.
Nano Banana Pro on Elyum
On Elyum, Nano Banana Pro is text-to-image and image editing at three listed resolutions: 1K at 5 credits ($0.05) per render, 2K at 7.5 credits ($0.07), and 4K at 10 credits ($0.10). Those figures already sit about 20 percent under comparable-platform anchors. You generate a take, look at the free preview, then KEEP it (credits leave) or KILL it (full refund, automatic). A failed generation is never charged. Paid plans kill freely. Free meters kills at one a month. Kept files download clean, no watermark, commercial use included.
Open the Nano Banana Pro model page for the current resolver. Run it from the web studio or from Claude, ChatGPT, and Cursor through Elyum's MCP docs and API docs. Free is up to 150 credits once (our algorithm may grant them), no card. Plus $9/mo, Pro $29/mo, Ultra $69/mo. Pro and Ultra include fair-use unlimited image generation on selected image models. More platform pairings sit on compare.

Where the two differ
Runway charges 4 credits when a Nano Banana image completes. Elyum charges only on KEEP. Preview is free. KILL is a full refund.
Runway returns credits only on a hard generation error. Finished-but-unusable frames stay billed. That policy is a frequent complaint on Trustpilot. Elyum never charges a failed generation and refunds KILLs (one KILL a month on Free; paid plans kill freely).
Elyum lists Nano Banana Pro at 1K, 2K, and 4K with separate rate tokens. Runway includes 4K upscaling on Standard and unlimited 4K upscaling on Pro and Max. Native Nano Banana Pro resolution on Runway is not published beyond the model listing.
Runway adds brand kits, voice clones, HDR/ProRes (Max), up to 3/5/10 projects, 5/15/20 parallel generations, and Aleph in-context video editing. Elyum is one studio, 50+ models, no timeline, no stock, no avatars, no mobile app, no team seats, no community feed.
Runway has a public developer API (docs.dev.runwayml.com) covering its own models and third-party models including Nano Banana. Runway MCP is listed on Pro. Elyum exposes the same studio via MCP and a REST API.
Paid Runway plans have no watermarks. Standard+ is positioned for commercial output in third-party summaries; Runway's own commercial-use terms were not directly quoted. Elyum kept takes have no watermark and commercial use included.
Pick Runway when
- You already need Gen-4.5, Aleph 2.0, brand kits, or HDR/ProRes in the same subscription as Nano Banana Pro.
- Standard ($15/mo, 625 credits) lists all AI video and image models, with 5 parallel generations and 4K upscaling.
- A public developer API and, on Pro, Runway MCP, if your pipeline is already on docs.dev.runwayml.com.
- Paid plans have no watermarks, and Max adds 9,500 credits, 20 parallel generations, and one month of credit rollover.
Pick Elyum when
- Free previews. You KEEP the Nano Banana Pro takes you want and KILL the rest for a full automatic refund.
- 1K, 2K, and 4K are 5 credits ($0.05), 7.5 credits ($0.07), and 10 credits ($0.10) per kept render.
- Free plan is up to 150 credits once (our algorithm may grant them), no card. Plus starts at $9/mo. Failed generations are never charged.
- One credit balance across 50+ models, plus MCP and REST, without a timeline you will not use for stills.

Getting the most out of Nano Banana Pro
- Put every on-image string in quotes and name its surface (poster masthead, soda can, laptop UI). Pro is strong at type, but paraphrased copy is what it invents.
- Lock aspect ratio and reading distance first: 1:1 pack shot, 4:5 ad, 16:9 key art, 9:16 story. A 4K file will not rescue a layout that was composed for the wrong frame.
- On edits, state the change and the freeze list (face, logo mark, key light, crop). Restating the whole scene is how you get a cousin, not a revision.
- Use camera nouns: 85mm, three-quarter, overcast softbox, practical neon, eye-level. Mood adjectives without a lens and a key light wander.
- Ask for one art direction. Editorial photo plus anime cel plus brutalist poster splits the model. Pick a primary and, if needed, one reference texture.
- For 4K, name the detail that must hold at 100 percent zoom (kerning on the wordmark, fabric weave, edge wear). Do not only write 4K or highly detailed.
