Enterprise AI platform and prebuilt applications for large organisations
A model-driven architecture that unifies data, analytics and applications around a shared ontology, so enterprise AI applications can be built and governed at scale.
A development environment where engineers and business analysts design, build and deploy enterprise AI applications, including natural-language-to-application generation with C3 Code.
Enterprise-grade generative AI grounded in proprietary data, returning cited answers across business functions and industries.
Production-ready applications encoding domain expertise across reliability, demand planning, production scheduling, process, inventory and sourcing optimization.
The open platform where the machine learning community hosts models, datasets, and AI apps
Search, download, and publish across millions of models and hundreds of thousands of datasets, complete with model cards, versioning, and citations.
Deploy Gradio, Streamlit, or static apps directly from a repository to show off a model, run comparisons, or share a tool with a public link.
Transformers, Diffusers, Datasets, Tokenizers, Accelerate, PEFT, TRL, and smolagents give you end-to-end tooling for training, fine-tuning, and inference.
Inference Providers route a single API to tens of thousands of models from multiple vendors, while Inference Endpoints spin up dedicated GPU hardware on demand.
