WaveSpeed AI vs Elyumfor Nano Banana 2
WaveSpeed AI bills every Nano Banana 2 call. Elyum charges only the takes you KEEP.
Nano Banana 2 is Google's stills model for text-to-image and image editing. It is built to keep a face, an outfit, or a product looking like itself when you move the subject into a new scene or change one thing in a frame. That identity lock is why people stay on it after they try a cheaper, looser generator. It is also fast enough that 1K drafts and a 4K final are the same workflow, not two different tools.
The weights are the same Google model. The bill is not. WaveSpeed AI is a pay-per-use API and playground: you pay for each generation, credits do not expire, and there is no subscription tier that unlocks the model. Elyum runs it as takes in one studio with one credit balance (1 credit = $0.01). You judge a free preview, then KEEP (credits charge) or KILL (full refund). Failed generations are never charged. WaveSpeed AI's refund-policy page lists an automatic refund within about 3 hours for failed requests, system errors, and timeouts. Details for this SKU sit on the Nano Banana 2 page. The wider WaveSpeed matchup is on the WaveSpeed alternative page.
WaveSpeed AI is the better fit if you already live in an API or ComfyUI graph and want Nano Banana 2 next to 1,000+ other checkpoints on one key. Elyum will not replace that stack. We do not ship a timeline editor, stock footage, avatars, a mobile app, team seats, or a community feed. We do ship a web studio plus the MCP docs and the API docs if you want the same keep/kill balance from Claude, ChatGPT, or Cursor. Trustpilot sat at 2.6/5 from four reviews as of 2026-09-07, a small sample; treat it as directional.
Nano Banana 2 on WaveSpeed AI
Nano Banana 2 is listed in WaveSpeed AI's model catalog next to Nano Banana Pro. WaveSpeed AI does not publish a per-image price for Nano Banana 2 in the sources checked, and it lists no subscription plans. Access is pay-as-you-go after a one-time $1 free-trial credit grant. No card is required to start. Some premium or partner models may be excluded from trial credits. Rate limits scale with Bronze, Silver, Gold, and Ultra account tiers based on cumulative top-up spend, not a monthly seat.
A failed request, system error, or timeout is supposed to auto-refund within about 3 hours per WaveSpeed AI's refund policy. Client-side timeouts in Sync Mode are not auto-refunded if the job finished on the server; retrieve it by prediction ID. A bad-but-complete image still bills. Credits never expire. Commercial-use terms sit on a separate policy page; the exact wording was not in the fetched excerpt. Paid watermark behavior is unpublished. One Trustpilot reviewer wrote that about half of a batch of 20 purchased generations came back unusable and that support did not respond to email.

Getting the most out of Nano Banana 2
- Lead with the lock. Name the person or product, then the new scene: same face, same jacket, same label, now on a wet Tokyo sidewalk at dusk. If you attached a reference, do not reinvent the face in prose.
- On edits, write the change and the freeze in the same prompt. Replace the sky. Keep the bottle, the condensation, and the typography identical. If you only describe the new part, Nano Banana 2 will invent the rest.
- Use camera nouns. 85mm, f/2, eye-level, soft side window light. Skip stacked mood words. The model follows lens, height, and light more reliably than cinematic as a vibe.
- Set aspect ratio before you write the shot. A wide establishing line in 9:16 will crop the subject. 4:5 for feeds, 9:16 for stories, 16:9 for ads, 1:1 when the product is the frame.
- One style anchor is enough. A second art movement or a second celebrity likeness averages the face. Add materials and light instead of extra styles.
- Do not ask for camera moves, extra frames, or a clip. Nano Banana 2 is stills. Lock the hero frame here, then take that file into a video model if you need motion.
