# Models The visualizer is a model aggregator: under the hood, every Generate Image and Generate Video click routes to one of several diffusion models from external providers. The dropdown is the working set, refreshed as providers ship new versions and as some get retired. This page is the working reference. Pick a model based on what your shot needs; the table below has one-line guidance per model. ## Image models | Model | Provider | When to reach for it | | -------------------- | ----------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Flux Pro Kontext** | Black Forest Labs | Photoreal stills with strong material rendering. Metallic, glass, and complex surfaces hold up well. Reference-image-conditioned and disciplined about it. | | **Flux2 Pro** | Black Forest Labs | Next-generation Flux. Cleaner subjects, finer detail, better at rendering text in the image when text matters. | | **Nano Banana Pro** | Google | The cinematic workhorse. Strongest with image references, especially for character consistency across shots. Default reach for hero shots when you have reference imagery. | | **Nano Banana 2** | Google | Sharper than Pro on certain stylized treatments. Picky about prompts; rewards specificity. | | **GPT Image 2** | OpenAI | OpenAI's image model in the working set. Different stylistic register from the Flux and Nano Banana families; useful as an alternative when the others flatten the subject. | ## Video models | Model | Provider | When to reach for it | | ---------------------- | --------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Veo 3.1** | Google | Wide latitude, slow generation. Best for atmospheric long-take shots where motion is naturalistic and you have time to wait. | | **Veo 3.1 Fast** | Google | Faster Veo at lower fidelity. Iteration-tier for atmospheric shots. | | **Kling 2.0 Master** | Kuaishou | Legacy master tier. Still supported; useful when consistency with previously rendered shots matters. | | **Kling 2.1 Standard** | Kuaishou | The everyday Kling. General-purpose, balanced cost vs quality. | | **Kling 2.1 Pro** | Kuaishou | Standard pro-tier video generation. Earlier-generation; Kling 2.6 Pro is the default action-shot reach today. | | **Kling 2.1 Master** | Kuaishou | Higher fidelity than Standard or Pro at the cost of generation time. | | **Kling 2.5 Turbo** | Kuaishou | Fast iteration. Use when you're cycling through compositions and want feedback in seconds. | | **Kling 2.6 Pro** | Kuaishou | Action-shot strong. Reach for it on motion-heavy shots. | | **Kling 3 Standard** | Kuaishou | Latest Kling family standard tier. | | **Kling 3 Pro** | Kuaishou | Latest Kling family pro tier. | | **Luma Ray 3** | Luma | Honors authored 3D structure most strictly. Reach for it when your shot has animated meshes, splined cameras, or specific motion the model needs to follow rather than reinterpret. | | **Runway Gen 4.5** | Runway | Alternative video model. Different tonal register than Kling and Veo; useful for stylistic variation. | | **Seedance 2.0** | ByteDance | Motion-strong model with first-and-last-frame support. Useful when the brief calls for fluid action and you want to hand the model two anchor frames. | ## Which AI model should I use? Direct answers per common job: | If your shot is | Reach for | Why | | ------------------------------------------------------------- | ------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------ | | Brand-true product hero with reference imagery | **Nano Banana Pro** | Strongest reference-image conditioning. Holds character and product across shots. | | Photoreal still with complex materials (glass, metal, fabric) | **Flux Pro Kontext** | Best surface fidelity. Disciplined about reference images. | | In-image text rendering matters (signage, packaging) | **Flux2 Pro** | Cleanest text generation in the working set. | | Stylized illustration or graphic look | **Nano Banana 2** | Sharper on stylized treatments. Reward specificity in the prompt. | | Atmospheric long-take video, naturalistic motion | **Veo 3.1** | Wide latitude. Slow but the best for ambient mood. | | Action-heavy video with motion | **Kling 2.6 Pro** | Action-shot strong. The chase-and-vehicle workhorse. | | Authored 3D motion needs to be honored exactly | **Luma Ray 3** | Honors keyframed and splined motion most strictly. | | First-and-last-frame video interpolation | **Veo 3.1**, **Kling 2.6 Pro** or later, or **Seedance 2.0** | These three model families currently support end frames. See [First and last frame](/visualize/first-and-last-frame.md). | | Fast iteration on a video composition | **Kling 2.5 Turbo** or **Veo 3.1 Fast** | Seconds-tier feedback. | ## Nano Banana Pro vs Flux Pro Kontext The two most-asked-about image models. Both are reference-image-disciplined; they differ in what they're tuned to honor. | | Nano Banana Pro | Flux Pro Kontext | | --------------------------- | ---------------------------------------------- | ------------------------------------------- | | Reference fidelity | Cinematic; consistent across shots | Photographic; consistent within a shot | | Material rendering | Strong on warm tones, skin, fabric | Strongest on glass, metal, complex surfaces | | Best for | Hero shot with character or product references | Hero shot with material-heavy products | | Cost tier | Standard | Standard | | Default reach when both fit | Cross-shot consistency wins | Single-shot material accuracy wins | For a campaign that needs multiple shots of the same product, Nano Banana Pro. For a one-shot hero of a watch, Flux Pro Kontext. For both at once, render the multi-shot story on Nano Banana Pro and the watch macro on Flux Pro Kontext. ## What to do past the first pass The answer is always "test against your specific shot". Different models honor different prompt languages differently; what reads cleanly on Nano Banana 2 may flatten on Flux2 Pro and vice versa. Burn 1K iterations comparing before committing video credits. ## When models change The model list churns. Providers ship new versions, sometimes retire older ones, occasionally pull capabilities out of free or lower tiers. The visualizer's dropdown is authoritative for what's currently available; this page tracks the names and the rough heuristics. If a model you've been using disappears from the dropdown, the most likely reason is the provider deprecated it. Pick the closest-named successor (Kling 2.6 Pro replacing Kling 2.6, for instance) and re-render to confirm the look survives. ## Older names you may see in transcripts Some YouTube tutorials and webinar talks reference earlier model names. The mapping: * *Kling 2.6* in the older transcripts is now **Kling 2.6 Pro**. * *Flux 1 Depth* (referenced in summit talk) is superseded by **Flux Pro Kontext** for general use. * *Flex* (mentioned in passing) was an older naming; see Flux Pro Kontext or Flux2 Pro for the current Black Forest Labs lineup. Use the current names everywhere in your work. The older names will still appear in older tutorial videos until the team re-records. ![Image model dropdown expanded with provider-grouped options: Black Forest Labs (Flux Pro Realtime, Fast Pro) and Google (Nano Banana Pro, Nano Banana 2)](/files/ByYbJ1RzPjqYzrL6zskO) ## Watch {% embed url="" %} ## Provider documentation Each provider has its own deeper docs for what their models can and cannot do at the system-prompt level: * Black Forest Labs Flux: [bfl.ai](https://bfl.ai) * Google Veo: [aistudio.google.com/models/veo-3](https://aistudio.google.com/models/veo-3) * Kuaishou Kling: [kling.ai](https://kling.ai) * Luma Ray: [lumalabs.ai/ray](https://lumalabs.ai/ray) * Runway: [runwayml.com](https://runwayml.com) Most users won't need the provider docs; the visualizer abstracts away most provider-specific syntax. For specialized model behaviors not exposed in Intangible's UI, the provider docs are the next stop. ## Related * [Generate image](/visualize/generate-image.md) * [Generate video](/visualize/generate-video.md) * [Resolution and cost](/visualize/resolution-and-cost.md) * [First and last frame](/visualize/first-and-last-frame.md) * [How the visualizer thinks](/overview/concepts/how-the-visualizer-thinks.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
