Together AI

Together AI is an AI acceleration cloud that empowers developers and enterprises to train, fine-tune, and run inference on open-source generative AI models. The platform gives access to 100+ open-source models via API, dedicated GPU clusters, and tools for fine-tuning and deployment — at a fraction of the cost of traditional cloud providers. In July 2026, Together AI raised an $800 million Series C led by Aramco Ventures at an $8.3 billion post-money valuation.
