Text Rendering & Typography

Text rendering is GPT Image 2's standout feature. It can generate readable text within images — signs, labels, headlines, UI elements, packaging text — with a level of accuracy that other models struggle to match. This makes GPT Image 2 the go-to model for creating mockups, concept art with embedded text, social media graphics with captions, and product images with readable labels.

Nano Banana 2 has improved text rendering significantly over the original Nano Banana, but it still occasionally produces garbled or misspelled text, especially with longer phrases. For short labels (1-3 words), Nano Banana 2 performs well. For longer text strings, paragraphs, or complex typography, GPT Image 2 is the clear winner. If your image needs readable text, use GPT Image 2. If text isn't critical, Nano Banana 2 offers better value and multi-image flexibility.

Reference Image Support

Nano Banana 2's 14-image reference support is a game-changer for creative workflows. You can provide a product photo, a lifestyle scene, a brand color palette, a typography reference, a mood board image, and more — all at once. The model blends all references to produce an image that respects each input. This is particularly powerful for brand teams, e-commerce, and marketing agencies that need to maintain visual consistency across campaigns.

GPT Image 2 supports reference images but typically works with fewer inputs. For simple image-to-image editing (one reference image + text prompt), GPT Image 2 produces clean, well-composed results. For complex multi-image blending, Nano Banana 2 is the more capable tool. The choice depends on your workflow: single-reference precision (GPT Image 2) vs multi-reference creative blending (Nano Banana 2).

Pricing Comparison

Nano Banana 2 is the more cost-effective option across the board. At 1K resolution, Nano Banana 2 costs 10 credits per image, and Nano Banana 2 Lite costs just 4 credits — making it one of the cheapest image models on Mivo. At 2K, Nano Banana 2 costs 14 credits. For a batch of 10 images at 1K, that's 100 credits (Nano Banana 2) or 40 credits (Lite).

GPT Image 2 commands a premium for its superior text rendering and composition quality. While exact pricing varies, it is more expensive per image than Nano Banana 2. For high-volume work where text accuracy isn't critical, Nano Banana 2 (or Lite) offers the best value. For images where readable text is essential, GPT Image 2's premium is justified by the time saved in post-production text fixes.

Frequently Asked Questions

Which model is better for text-in-image rendering?▼
GPT Image 2 (OpenAI) has historically been stronger at rendering readable text within images, particularly for signs, labels, and UI mockups. Nano Banana 2 has improved significantly in text rendering over the original Nano Banana but still occasionally struggles with longer phrases. For complex typography and long text strings, GPT Image 2 is the safer choice. For short labels and simple text, both perform well.
How many reference images does each model support?▼
Nano Banana 2 supports up to 14 reference images for image-to-image generation, allowing complex multi-image blending workflows. GPT Image 2 supports reference images but typically fewer. If your workflow involves blending multiple visual references (product + style + background + color palette), Nano Banana 2 offers more flexibility.
Which model is cheaper on Mivo?▼
Nano Banana 2 is cheaper. At 1K resolution, Nano Banana 2 costs 10 credits per image vs GPT Image 2's higher pricing. Nano Banana 2 Lite is even cheaper at 4 credits per image. For high-volume image generation, Nano Banana 2 at 10 credits offers excellent value. For budget work, Nano Banana 2 Lite at 4 credits is one of the cheapest image models on Mivo.
What resolutions do they support?▼
Nano Banana 2 supports 1K and 2K output resolutions. Nano Banana 2 Lite offers 1K only at a lower cost (4 credits). GPT Image 2's resolution options vary by implementation. For consistent 2K output, Nano Banana 2 at 14 credits per 2K image is a strong value. For 1K work, Nano Banana 2 Lite at 4 credits is the most affordable option.
Which model is better for product photography?▼
Both models excel at product photography but in different ways. Nano Banana 2 with its 14-image reference support lets you provide product photos, lifestyle scenes, and brand guidelines simultaneously — producing images that blend all references. GPT Image 2 produces clean, well-lit product shots with excellent text rendering for labels and packaging. For multi-reference product scenes, Nano Banana 2 wins. For single-product shots with text labels, GPT Image 2 is better.
Can I use both models on Mivo?▼
