Updated June 15, 2026Together AI is an AI infrastructure company founded in 2022, providing a cloud platform for running, fine-tuning, and building with open-source AI models. The company has raised over $200 million and has become one of the leading alternatives to proprietary AI model APIs.
Together's platform offers fast inference for popular open-source models (Llama, Mistral, Qwen, and many others), fine-tuning services for customizing models on proprietary data, and training infrastructure for organizations building their own models. The company's inference speeds are competitive with the fastest available (rivaling Groq on many benchmarks) while offering a much broader selection of models.
Together AI serves as the infrastructure layer for organizations that want to use open-source models without managing GPU infrastructure directly. The company competes with Baseten, Replicate, and cloud provider endpoints, while also offering unique capabilities like Together Embeddings and a research focus on efficient AI training methods (contributing to papers on sparse attention, mixture-of-experts, and data-efficient training).
