PRODUCT OVERVIEW

What is Together AI?

Together AI is a full-stack AI Native Cloud built for developers and teams running open-source models in production. It offers serverless inference APIs across chat, vision, image, audio, video, transcription, embeddings, rerank and moderation models, plus batch inference, provisioned throughput with SLAs, dedicated model and container inference, and Together Link for running open models inside existing harnesses. Beyond inference, the platform provides GPU clusters, an AI factory, sandbox developer environments and managed storage, alongside model shaping tools for post-training, fine-tuning and evaluations. Teams can start with serverless inference and move to dedicated endpoints at scale, or contact sales for custom capacity.

How to use Together AI

  1. 1

    Create an account and sign in

    Sign in at api.together.ai to access the platform console and API.

  2. 2

    Choose an inference mode

    Start with serverless inference for most workloads, or explore batch inference, provisioned throughput, dedicated model inference or dedicated container inference.

  3. 3

    Explore the model library

    Browse chat, image, code, vision and video models in the model library, or open the playground to test models.

  4. 4

    Shape models with post-training and fine-tuning

    Use post-training to define RL and SFT loops, launch managed SFT and DPO fine-tuning jobs, and measure model quality with evaluations.

  5. 5

    Scale compute as needed

    Provision GPU clusters, use the AI factory for custom infrastructure, build in sandbox environments and store model weights with managed storage.
