[Read the API docs](https://docs.rainbrand.com/api). AI Gateway FAQ ## Asked, answered. [All FAQs](https://www.rainbrand.com/faq/) ### What can I create with Rainbrand's AI Gateway? Images, videos and speech, using the models available through Rainbrand. Published examples include product photos, campaign images, animated product shots and voiceovers. Agents can combine those outputs with code and design tools to make pages, packaging and complete campaigns. [See the Teenage Engineering run](https://www.rainbrand.com/integrations/chatgpt/). ### Which AI models can I use? For images: Google's Nano Banana 2.1, OpenAI's GPT Image 2.5 Flare and Sunburst, and ByteDance's Seedream 5 Pro. For video: ByteDance's Seedance 2.5. For speech: ElevenLabs' Eleven v4. Your agent can list the current models and read their options before generating. [See how to choose a model](https://docs.rainbrand.com/api-reference/models/list-models). ### How do I make AI images and videos on-brand? Request a Brief and include it with a supported generation request. Rainbrand passes its guidance and visual references to the model alongside your prompt. Your prompt specifies the content and exact wording. Check the result with a Review, using an image or captured video frame, then revise where needed. [Read about keeping AI assets on-brand](https://www.rainbrand.com/blog/keep-ai-generated-content-on-brand/). ### Can I use my own images and references? Yes, where the selected model supports them. You can supply references alongside a Brief, or animate a starting image with a supported video model. The accepted formats, number of references and combinations depend on the model. [Follow the product-video example](https://docs.rainbrand.com/use-cases/product-video). ### Can I make different versions of the same campaign? Yes. Reuse a relevant Brief and change the prompt, composition or dimensions for each generation. The rabbit example explores three campaign directions, then generates square and landscape versions of the selected one. [See the campaign-image guide](https://docs.rainbrand.com/use-cases/campaign-image-set). ### How does audio use our brand voice? Your agent uses the brand guidance to write the words, then sends the script to a speech model with a selected voice. The brand's tone comes through the writing; the spoken voice is a model setting. Your agent can retrieve the audio for you to listen to. ### Do I need separate accounts or API keys for each model? No. Access the available models through your Rainbrand connection or API key. You can also keep using your own generation tools with a Brief's guidance and assets. The AI Gateway is optional.
