Picking between Ideogram V4 and Nano Banana 2 usually comes down to one question: does this image need to carry text, or does it need to look real? Both models are live on hiapi and reachable with the same API key, but they solve different problems well enough that treating them as interchangeable wastes money on the wrong tier.
This comparison uses the same prompt on both models, hiapi's current live pricing, and each model's actual parameter schema — no vendor marketing copy.
What Each Model Is Actually Good At
Ideogram V4 is built around typography. It renders multi-line text, curved text along a badge or seal, and small caption text with far fewer garbled characters than most diffusion models. It ships three rendering-speed tiers — TURBO, BALANCED, and QUALITY — trading render time for text accuracy. It's text-to-image only; there's no image-to-image endpoint.
Nano Banana 2 is built around resolution and photorealistic detail, with a text-to-image endpoint and an image-to-image endpoint (edit or restyle an existing image). It ships three resolution tiers — 1K, 2K, and 4K — and licenses output for commercial use.
The coffee-brand logo above is a fair example of Ideogram V4's strength: two lines of curved text, a small icon, and a single ink color — all legible at a glance, no melted letterforms.
Nano Banana 2 handles headline-plus-subtitle text reasonably well too, but its edge is in the surrounding scene: the gradient sky, the scanline texture, the lighting — detail that would take Ideogram V4 noticeably longer to approximate.
Head-to-Head: Same Prompt, Two Models
To compare them on equal footing, we ran the identical prompt — a product-launch poster for a ceramics studio, with a bold headline, a subheading, and a centered product shot — through both models at a matched 3:4 aspect ratio.
Ideogram V4 (QUALITY tier) placed the headline and subheading exactly where the prompt specified, in clean, fully legible sans-serif — this is the kind of output you can ship to a client without a retouch pass.
Nano Banana 2 (2K) rendered the ceramic mug itself with more convincing glaze texture and studio lighting, but the headline text is slightly less crisp at small sizes than Ideogram V4's.
The pattern holds across both tests: Ideogram V4 wins when text is the point of the image; Nano Banana 2 wins when the surrounding visual has to look photographically real.
Pricing Comparison
| Model | Tier | Price / image | Notes |
|---|---|---|---|
| Ideogram V4 | TURBO | $0.05 | Fastest, lowest text fidelity |
| Ideogram V4 | BALANCED | $0.10 | Default choice for most jobs |
| Ideogram V4 | QUALITY | $0.17 | Best text accuracy, slowest |
| Nano Banana 2 | 1K | $0.036 | Lowest resolution and lowest price |
| Nano Banana 2 | 2K | $0.057 | Mid-resolution tier |
| Nano Banana 2 | 4K | $0.086 | Highest resolution |
Nano Banana 2's regular price increases with resolution: $0.036 at 1K, $0.057 at 2K, and $0.086 at 4K. Choose 1K for the lowest per-image price, or pay more for 2K/4K when the output needs the extra resolution.
Which One Should You Pick?
- Logos, badges, posters, UI mockups with real copy → Ideogram V4, QUALITY tier if the text is customer-facing, BALANCED for internal drafts.
- Product photography, illustrations, scene generation, or editing an existing image → Nano Banana 2, 2K tier by default, 4K only when the output needs to be printed or cropped tightly.
- Both, in the same pipeline → generate the hero illustration on Nano Banana 2, then generate the logo or headline treatment separately on Ideogram V4 and compose them. This is what we did for this article's own images.

FAQ
Does Ideogram V4 support image-to-image editing? No. Ideogram V4 on hiapi is text-to-image only. For editing an existing image, use Nano Banana 2's image-to-image endpoint instead.
Which model is cheaper for a high-volume batch job? At regular rates, Nano Banana 2 at 1K ($0.036/image) is the cheapest option overall. Ideogram V4 TURBO ($0.05/image) is the lowest-priced Ideogram tier, trading fidelity for speed.
Can I use either model's output commercially? Yes, both models' outputs on hiapi carry commercial usage rights. Always check the current terms on the model's pricing page before shipping to production.
Do I need separate API keys for each model? No. Both models are reachable through the same hiapi API key and the same /v1/tasks endpoint — you only change the model field in the request body.
Takeaways
Ideogram V4 and Nano Banana 2 aren't really competing for the same job. If your image lives or dies on the text inside it, Ideogram V4's QUALITY tier costs $0.113 more per image than Nano Banana 2 at 2K ($0.17 vs $0.057); decide whether the typography improvement shown here warrants that difference. If the text is secondary to the scene, Nano Banana 2 at 2K is both the sharper and the cheaper choice. Ready to test both? Check hiapi pricing and start with the same API key you already have.
