All AI Models tools
SeedRouter provides a unified API platform designed to simplify the integration of various artificial intelligence models into products. It offers a single API key to access a wide range of image, video, language, and audio models, ensuring developers only pay for successful requests and delivered results, eliminating costs for failed attempts. The platform is built to make adding AI capabilities a deliberate choice rather than a speculative guess. It offers clear model access, allowing users to review model capabilities, parameters, and pricing before writing any code. SeedRouter also enables flexible model choices, allowing developers to switch between different model families like GPT, Claude, or Gemini, or even between image and video models, without needing to rewrite their underlying stack. By centralizing access and standardizing the request shape, SeedRouter ensures that integrations are robust and production-ready. This approach helps product teams efficiently explore and deploy advanced AI functionalities, from generating high-resolution images and videos to leveraging large language models with extensive context windows, all through a consistent and reliable interface.
What are AI model platforms?
This category covers platforms that provide access to AI foundation models: the large language, image, video and audio models that power generative apps. They expose these models through APIs, playgrounds or hosting, so developers can call them without training their own.
Core features
- API access to hosted foundation models
- One interface across model providers
- Image, video, audio and text models
- Playgrounds for testing prompts
- Usage-based, pay-as-you-go pricing
- Open and proprietary model options
Who uses AI model platforms
01
Developers
Call ready-made models through an API instead of training and hosting your own.
02
AI product teams
Compare and switch between model providers behind one interface.
03
Researchers & tinkerers
Test the latest open and proprietary models in a playground.
How AI model platforms work
These platforms host or aggregate trained models and serve them over an API. A request sends your prompt or input to the chosen model, which runs on the provider's infrastructure and returns the generated text, image, audio or video, billed by usage.
