What is Together AI?
Together.ai is a U.S.-based artificial intelligence infrastructure company focused on building an open, scalable platform for training, fine-tuning, and running large AI models. Founded in 2022 and headquartered in San Francisco, California, Together.ai’s mission is to make advanced AI systems more open, transparent, and accessible, enabling developers and enterprises to build and deploy generative AI applications without relying solely on closed, proprietary platforms. The company positions itself as a core infrastructure provider for the open-source AI ecosystem.
Technology & Products
Together.ai offers a cloud-based AI compute and inference platform optimized for large-scale model training and deployment, supporting popular open-source models such as LLaMA, Mistral, Falcon, and Stable Diffusion. Its stack combines high-performance GPU clusters, optimized inference engines, fine-tuning tools, and APIs that allow customers to deploy models efficiently at scale. A key technical differentiator is the company’s focus on performance optimization and cost efficiency, enabling faster inference and lower latency for production workloads while maintaining flexibility across model architectures. Together.ai also actively contributes to and collaborates with the open-source AI community, reinforcing its position as an infrastructure layer rather than a model owner.
Market Opportunity
Together.ai addresses the rapidly expanding market for generative AI infrastructure, serving startups, enterprises, and researchers building AI-powered products across industries such as software, media, research, and enterprise automation. As demand grows for alternatives to vertically integrated AI platforms, the need for independent, scalable compute and inference providers is increasing. The proliferation of open-source foundation models and enterprise requirements for customization, data control, and cost predictability create a favorable market environment for Together.ai’s open and modular approach to AI infrastructure.
Competitive Landscape
Together.ai operates in the competitive AI cloud and model infrastructure layer, alongside hyperscale cloud providers and emerging AI infrastructure startups. Unlike general-purpose cloud platforms, Together.ai differentiates itself by focusing specifically on open-source model support, optimized inference performance, and developer-centric tooling. This positioning appeals to customers seeking flexibility, transparency, and reduced vendor lock-in compared to proprietary model ecosystems. While competition is intense, Together.ai’s specialization in open AI infrastructure and strong alignment with the open-source community distinguish it from more closed or vertically integrated competitors.
