The financing comes as companies building with AI confront an uncomfortable truth: frontier-model pricing can eat their entire margin. Together AI has emerged as the infrastructure layer for the alternative — helping companies train and run workloads on open models like DeepSeek, Nemotron, MiniMax, and Kimi at a fraction of the cost of closed systems, with comparable or better performance. With one of the leading AI research labs in the world, Together AI has been pushing the frontier of inference, delivering industry leading performance for the demanding AI applications.
