All Nano Banana Models Explained — Image, Video, and Music Generation

Nano Banana Free gives you access to over a dozen AI models from Google, OpenAI, ByteDance, Black Forest Labs, and Kie — all through a single platform at nanobananafree.co without configuring API keys or managing separate subscriptions. Whether you are trying to understand what is Nano Banana, comparing Nano Banana 2 vs Nano Banana Pro, or looking for the right model for a specific task, this guide breaks down every model currently available and tells you exactly when to use each one.

Image Generation Models

The AI image generator on Nano Banana Free supports six distinct models. Each has a different provider, architecture, and output character.

Nano Banana 2

Nano Banana 2 is Kie's proprietary image model and the default starting point for most creators on the platform. It supports both text-to-image and image-to-image workflows. Its defining strengths are character consistency across iterative prompts and natural language editing — you describe the change you want in plain English and the model applies it without disrupting the rest of the composition. Generation is fast, which makes it ideal for rapid prototyping, building a prompt library, and daily creative work. If you are new to the platform, Nano Banana 2 is where you start.

Nano Banana Pro

Nano Banana Pro is the high-output counterpart to Nano Banana 2, available via Replicate and Fal. It delivers noticeably higher detail and resolution than the base model, with improved handling of fine textures, complex lighting setups, and edge sharpness. The credit cost is higher per generation, which reflects the compute required. Nano Banana Pro is the right choice when you need commercial-grade deliverables — client work, print assets, product imagery, or any output where standard resolution is insufficient. For a detailed side-by-side comparison, read What is Nano Banana 2.

Nano Banana Pro 2

Nano Banana Pro 2 builds on the original Pro architecture with refinements to consistency and detail rendering. It is available via Replicate and Fal and supports the same text-to-image and image-to-image workflow as its predecessor. Where Nano Banana 2 Pro improves most visibly is in portrait work and stylized illustration — scenes requiring fine facial detail or coherent line art benefit from the additional rendering depth. Use it when Pro output quality is needed but prompt complexity is especially high.

Seedream 4

Seedream 4 is ByteDance's image generation model, accessed through Replicate. It handles both text-to-image and image-to-image generation with a particular strength in photorealistic and stylized outputs. The model processes compositional prompts well — multi-subject scenes, architectural interiors, and fashion visuals with specific lighting conditions all render with good fidelity. If you are working on e-commerce imagery or visually dense scene prompts and want an alternative rendering engine to compare against Nano Banana 2, Seedream 4 is worth testing.

Z-Image Turbo

Z-Image Turbo is a text-to-image model available via Fal, optimized for generation speed above all else. Output quality is competitive but the standout feature is how quickly results arrive — useful when you need to test a large number of prompt variations in a single session without waiting between each generation. Z-Image Turbo is a good choice for early-stage concept exploration where you are iterating quickly through ideas before committing to a higher-cost model run.

Flux 2 Flex

Flux 2 Flex is developed by Black Forest Labs and served through Fal. It is a text-to-image model that offers flexible style control across photorealistic, illustrated, and abstract output modes. Black Forest Labs built Flux with a focus on style range — the same model handles a cinematic photograph prompt and a flat vector illustration prompt without needing separate fine-tuned versions. Use Flux 2 Flex when you are exploring a visual direction and want maximum stylistic flexibility from a single model.

Gemini 3 Pro Image Preview

Gemini 3 Pro Image Preview is Google's multimodal model, supporting both text-to-image and image-to-image generation. Its competitive advantage is prompt comprehension — Gemini processes complex, multi-clause descriptions with more fidelity than most image-focused models, making it particularly effective for detailed scene compositions where every element in the prompt matters. If your prompt describes a specific spatial arrangement, a nuanced emotional tone, or a scene with many simultaneous elements, Nano Banana Gemini is the model most likely to interpret it accurately.

Video Generation Models

The AI video generator on Nano Banana Free includes four model options spanning text-to-video, image-to-video, and video-to-video workflows.

Veo 3 and Veo 3.1

Veo 3 and its updated variant Veo 3.1 are Google's video generation models. Both support text-to-video and image-to-video generation. Veo produces high-quality motion with strong scene coherence — objects move in physically plausible ways, camera movements feel intentional, and cuts between scenes hold together without the temporal artifacts that affect lower-tier video models. Nano Banana video creators working on product demos, short-form social content, or visual storytelling will find Veo 3.1 to be the most reliable option for polished, shareable output.

Sora 2 and Sora 2 Pro

Sora 2 and Sora 2 Pro are OpenAI's video generation models, available through Replicate and Kie. They support text-to-video and image-to-video generation. Sora is known for cinematic output quality — rich depth of field, natural motion blur, and a visual language that reads as intentionally filmed rather than AI-generated. Sora 2 Pro extends the base model with higher resolution output and longer generation windows. For narrative or brand-level video content where production value is the priority, Sora 2 Pro is the top-tier choice on the platform.

Wan Pro

Wan Pro is available via Fal and specializes in image-to-video conversion. Where text-to-video models start from a written description, Wan Pro takes a still image as its primary input and animates it — adding motion, atmospheric effects, or character movement that feels consistent with the original visual. It is particularly effective for breathing life into character portraits, product shots, and illustrations. If you have already generated a strong image with one of the image models and want to add motion, Wan Pro is the natural next step.

Kling Video O1

Kling Video O1 is ByteDance's video model and currently the only video-to-video option on the platform. It takes an existing video clip as input and applies style, motion, or scene edits while preserving the original action and pacing. Use cases include style transfers on existing footage, adding atmospheric effects to raw clips, and converting rough video drafts into polished final outputs. Kling Video O1 is the right tool when you are working with existing video material rather than generating from scratch.

Music Generation

Kie V5

Kie V5 is currently the only music generation model on Nano Banana Free, and it covers the full range of audio production needs most creators encounter. It supports two generation modes: custom mode, where you specify a title, style, and whether the track should be instrumental or include vocals; and prompt mode, where you describe the mood, genre, and energy level in plain language and the model composes accordingly. The output is a complete audio track ready for use in video projects, social content, or standalone publishing. Visit the AI music generator to try it directly.

How to Choose the Right Model

The right model depends on what you are making and how far into the creation process you are.

Starting a new image concept? Use Nano Banana 2. It is the fastest and most credit-efficient way to test ideas. Run several prompt variations before deciding which direction to develop further.

Need a deliverable-ready image? Switch to Nano Banana Pro or Nano Banana Pro 2 once you have locked in the composition and prompt. The extra resolution and detail quality justifies the higher credit cost at this stage.

Working with a complex or highly specific prompt? Try Gemini 3 Pro Image Preview. Its multimodal architecture gives it an edge on prompts with many simultaneous requirements or nuanced spatial descriptions.

Exploring an unfamiliar style range? Flux 2 Flex handles the widest style variation from a single model. Good for discovering visual directions before committing to a specific aesthetic.

Making a short video from a text description? Start with Veo 3.1 for the most consistent motion quality. Use Sora 2 Pro if you need cinematic production value and are working on brand or narrative content.

Animating an existing image? Wan Pro is purpose-built for this. Generate a strong image first, then pass it to Wan Pro to add motion.

Editing existing video footage? Kling Video O1 is your only option on the platform and handles video-to-video work well.

Creating background music? Kie V5 covers both quick prompt-based generation and precise custom mode composition. Use custom mode when you need a specific genre and instrumentation.
