WaveSpeed AI vs Elyumfor Nano Banana Pro
Elyum charges 10 credits ($0.10) only when you keep a 4K take, while WaveSpeed AI bills pay-per-use and does not publish a Nano Banana Pro unit price.
Nano Banana Pro is Google's 4K image model. The useful part is the type. Headlines on a poster, UI strings on a mock, a SKU line on a pack: it usually lands the letters, not a mush of near-words. Native 4K is enough for ad work if you ask for the small type, not only the hero product. It does text-to-image and image editing in one model, with 11 aspect ratios. You already like those weights. This page is about where a take costs less, what a bad take costs, and which limits differ.
WaveSpeed AI is an API-first aggregator: one key, a playground, pay-per-generation, no monthly plan. Elyum is one studio and one credit balance. On the Nano Banana Pro page the keep prices are 5 credits ($0.05) at 1K, 7.5 credits ($0.07) at 2K, and 10 credits ($0.10) at 4K. WaveSpeed AI confirms the model and 4K-capable edit output. It does not publish a Nano Banana Pro unit price in the sources for this page. Failed jobs and killed takes are the other split. WaveSpeed AI auto-refunds many failures in about three hours. Elyum never charges a failure, and a kill refunds the keep.
Caveat: WaveSpeed AI is the better host if you need ComfyUI nodes and a 1,000+ model catalog on one invoice. Elyum has no timeline editor, stock footage, avatars, mobile app, team seats, or community feed. Check WaveSpeed AI's own pricing page for any live Nano Banana Pro rate this page cannot quote. A fuller platform rundown is on the WaveSpeed alternative page, and Nano Banana 2 has its own WaveSpeed AI vs Elyum for Nano Banana 2 writeup.
Nano Banana Pro on WaveSpeed AI
WaveSpeed AI offers Nano Banana Pro with a dedicated landing page and 4K-capable editing output. No monthly plan unlocks it. WaveSpeed AI's pricing page is pay-as-you-go: a one-time $1 trial grant, no card required to start, and some premium or partner models may be excluded from trial credits. WaveSpeed AI does not publish a Nano Banana Pro per-image price in the sources for this page. Account tiers (Bronze, Silver, Gold, Ultra) raise rate limits with cumulative top-up spend.
WaveSpeed AI's refund policy says failed requests, system errors, and timeouts get an automatic refund within about 3 hours. Client-side timeouts in Sync Mode are not auto-refunded if the job actually finished server-side; retrieve it by prediction ID. Credits do not expire. The product is API-first (one key across hosted models), plus a web playground and a ComfyUI node pack. Commercial-use terms sit on a separate policy page; specific terms were not captured in the fetched excerpt, so this page will not invent them. Watermark behavior on paid files is not published.

Where the two differ
WaveSpeed AI charges pay-as-you-go per generation, with no subscription tiers. Elyum uses credits (1 credit = $0.01) on Free, Plus $9/mo, Pro $29/mo, and Ultra $69/mo, plus top-ups. Listed Nano Banana Pro keeps are $0.05 / $0.07 / $0.10. WaveSpeed AI's Nano Banana Pro unit price is not published.
WaveSpeed AI's refund-policy page describes an automatic refund within about 3 hours for failed requests, system errors, and timeouts. Sync Mode client timeouts are not auto-refunded if the server finished the job. Elyum never charges a failed generation. A killed preview refunds in full (one kill a month on Free).
WaveSpeed AI documents Nano Banana Pro edit output up to 4K. Elyum sells three keep tiers: 1K at 5 credits ($0.05), 2K at 7.5 credits ($0.07), and 4K at 10 credits ($0.10). This page does not invent a WaveSpeed AI 1K or 2K SKU.
WaveSpeed AI's core product is the API, plus a playground and a ComfyUI node pack (WaveSpeedAI/wavespeed-comfyui). Elyum is a web studio plus MCP and REST, with no timeline editor, stock, avatars, or mobile app. Other image SKUs sit in the models catalog.
WaveSpeed AI points to a separate Commercial Use Policy; the fetched excerpt did not include the specific terms, and watermark-on-paid is not published. Elyum kept takes have no watermark, full quality, and commercial use included. Do not assume WaveSpeed AI matches that without reading its policy.
WaveSpeed AI aggregates 1,000+ models on one key and one bill, with credits that do not expire. Elyum lists 50+ models in one studio. WaveSpeed AI has no subscription lock-in. Elyum's Plus, Pro, and Ultra are monthly plans; Free is a one-time 150-credit grant.
Pick WaveSpeed AI when
- You want one API key and one invoice across 1,000+ models, not a 50+ studio catalog.
- You run ComfyUI and want the WaveSpeedAI/wavespeed-comfyui node pack next to Nano Banana Pro.
- You prefer pay-as-you-go with no monthly plan and credits that WaveSpeed AI says never expire.
- You top up into Bronze, Silver, Gold, or Ultra so rate limits scale with spend rather than a seat.
Pick Elyum when
- A kept 4K take is 10 credits ($0.10); 1K is 5 credits ($0.05). You see the keep price before you pay.
- Every render is a free preview. Kill refunds the keep. Failed generations are never charged.
- You want one credit balance across Nano Banana Pro and the rest of the studio, plus MCP or REST from Claude, ChatGPT, or Cursor.
- Kept files download without a watermark, at full quality, with commercial use included.
Nano Banana Pro in three styles, rendered on Elyum
Getting the most out of Nano Banana Pro
- Put every on-image string in quotation marks and name its placement (headline top-third, SKU bottom-right). Nano Banana Pro holds type well, but a vague add-text request still drifts.
- Ask for 4K when the type is small (packaging legal lines, UI labels). 1K is 5 credits ($0.05) and cheaper, but 8-pt strings smear. 4K is 10 credits ($0.10) when you keep it.
- For edits, name what must not change (logo geometry, product silhouette) and what may (headline copy, background). One change per pass is cleaner than a full rewrite.
- Set the aspect ratio to the end use (9:16 story, 4:5 ad, 1:1 pack). The model supports 11 ratios. Do not leave a default and crop later if the letters are the point.
- This is a still. Skip pan, dolly, and frame-rate talk. Use frame language: 85mm, overhead, three-quarter pack shot, soft box from camera left.
- If letters fail, shorten the copy and name a font family and weight (bold grotesque, light serif) instead of restating perfect typography.
