infoAbout Hedra

Hedra is a visual AI platform that provides models, training tools, and inference infrastructure for generating and working with images and video. The company builds frontier visual models—diffusion models, video models, and world models—and operates the platform that runs them in production. The platform includes three main components. Managed Inference offers API access to over 100 visual models with the vendor handling hosting and infrastructure. Hedra Training allows fine-tuning of supported visual models with custom data, including pre-training, post-training, and reinforcement learning for task-specific objectives. GPU Sandboxes provide isolated GPU environments for running custom model code, video pipelines, and simulations through a software development kit. Hedra also provides Studio, a no-code workspace for creating and iterating on image and video content. The platform offers WMR (World Model Runtime), an inference engine built specifically for multimodal training and generation, with optimizations for diffusion, video, and world models. Deployment options include managed cloud, hybrid or customer infrastructure, and on-premises sovereign deployment. The platform suits developers building visual AI applications, researchers training custom models, and teams creating visual content. The vendor reports 12 million outputs generated and is backed by Andreessen Horowitz, Index Ventures, Abstract Ventures, and Alexa Fund.
