Together AI offers a generative AI platform that serves open-source large language, image, video, and multimodal models through both serverless and dedicated endpoints. Developers can run inference on demand, submit batch jobs across large volumes of prompts, or reserve GPU clusters for sustained production traffic.

The platform includes fine-tuning and training tools, an open-source model catalog spanning Llama, Mixtral, Qwen, and custom checkpoints, and OpenAI-compatible APIs that let existing applications switch providers with minimal changes.
