What it does

Hedra accepts image, text, audio and video inputs through its API or Studio web app and returns generated media, speech, music or text answers. Developers can send an image and a question to the chat completions endpoint for an immediate text response, or submit asynchronous jobs to produce video, image, speech or audio.

Teams use the API to add visual generation, lip-sync, upscaling, speech, music or scene understanding to their own applications, paying per output or per token from a prepaid balance. Hedra also offers its World Model Runtime for diffusion, video and world models, along with managed, hybrid or on-premises deployment and custom model work with its researchers.

Hedra suits developers and product teams building visual or multimodal products who want hosted inference without running their own serving stack. Access requires creating an API key with chat:write access and funding the API wallet, which is separate from Studio credits. Dedicated serving, training and GPU execution are quoted per engagement, and per-model rates and limits can change, so check the model catalog and rate table before committing.
