Private AI Cloud for Creators & Developers — ComfyUI, Model APIs, and GPUs

HexGrid Cloud is building the infrastructure that makes powerful AI models accessible to everyone. We're creating a private AI cloud where developers, creators, and AI teams can deploy cutting-edge generative models, launch ready-to-use ComfyUI workflows, and access dedicated GPUs without the complexity of managing infrastructure. Our platform brings together three core capabilities: - ComfyUI Cloud: Launch preconfigured image and video generation workflows with models like MiniMax H3, Wan, LTX, and FLUX. Bring your own models, custom nodes, and LoRAs. - On-Demand GPU Cloud: Access dedicated NVIDIA GPUs, including H100, H200, A100, and B200, with transparent pricing and full control over your environment. - AI Model APIs: Integrate powerful AI models into applications without managing the underlying infrastructure.
