About Together AI
Together AI runs a cloud platform where developers train, fine-tune and run generative AI models, with a focus on open-source models such as DeepSeek rather than a single proprietary one. Fine-tuning means adjusting an existing model on a customer's own data. The company rents GPU capacity and sells access through an inference service, meaning the step where a trained model answers requests. It was founded in 2022 in San Francisco by Vipul Ved Prakash, Ce Zhang, Chris Re and Percy Liang. Prakash is chief executive. It is a cloud service rather than a chip maker.
Together AI was founded in 2022 and is based in San Francisco, CA, United States. It is listed under AI Accelerators. Reported funding is $305M Series B (Feb 2025, $3.3B val); reportedly raising $1B at $7.5B (Mar 2026).
