Overview

Together AI is a cloud platform purpose-built for running open-source AI models with optimized performance and competitive pricing. The platform hosts over 100 popular open-source models including Llama 3, Mistral, DBRX, Stable Diffusion, and more — all accessible through an API that follows the OpenAI chat completions format.

What sets Together AI apart is its infrastructure optimization. The company has built custom inference engines that deliver significantly faster token generation compared to running models on generic cloud GPU instances. Their serverless endpoints scale automatically, so developers only pay for the tokens they generate.

Beyond inference, Together AI offers fine-tuning capabilities that let teams customize open-source models on their own data. The platform also provides dedicated GPU clusters for organizations that need guaranteed capacity. Together AI has become a popular choice among developers who prefer open-source models but want the convenience of managed cloud infrastructure.
