Together AI provides a comprehensive cloud platform designed specifically for developing and scaling AI-native applications with open-source generative models. The platform delivers full-stack capabilities spanning inference, fine-tuning, pre-training, and GPU infrastructure, enabling developers and researchers to build production-ready AI systems without the complexity of managing their own infrastructure. Built on cutting-edge research innovations and frontier hardware, Together AI offers unmatched price-performance through technologies like the ATLAS speculator system and Together Inference Engine.

The platform supports a vast library of open-source and specialized models across multiple modalities including text, images, videos, and code, with OpenAI-compatible APIs for seamless migration from closed models. Together AI's serverless inference provides reliable deployment at scale with breakthrough performance optimizations, while fine-tuning capabilities allow organizations to create task-specific models that remain fully owned by the customer. Pre-training services enable secure and cost-effective development of custom foundation models leveraging research advances like the Together Kernel Collection.

Together AI operates globally distributed GPU clusters featuring the latest NVIDIA hardware including GB200 NVL72 and GB300 NVL72 systems across 25 cities. The infrastructure supports instant self-serve clusters as well as custom AI factories for high-scale workloads, with options ranging from individual GPUs to deployments exceeding 100,000 NVIDIA GPUs. The platform emphasizes transparency, privacy, and customer ownership, allowing teams to inspect model training data, maintain complete data control, and avoid vendor lock-in. Together AI's continuous research capability and open-source contributions create a technical differentiation that benefits the broader AI community while driving platform innovation.
