Together AI

Together AI is a comprehensive cloud platform designed to accelerate the development and deployment of generative AI models. It offers the fastest available inference stack, dedicated GPU clusters for training, and the capability to build custom models. With an emphasis on open-source and privacy, Together AI facilitates model fine-tuning with private data, ensuring users retain full ownership.

Their offerings include Together Inference, Together Fine-tuning, Together Custom Models, and Together GPU Clusters, catering to various needs from model fine-tuning with your data to hosting models for inference and providing high-end compute clusters for large-scale training and fine-tuning tasks​

Pricing is highly competitive and varies across services:

Inference pricing is based on the model size and the number of tokens processed, with special promotional pricing for Llama-2 and CodeLlama models​​.

Dedicated instances for hosting your own model are charged hourly based on the hardware type and model size​​. Fine-tuning pricing depends on model size, dataset size, and the number of epochs, with an interactive calculator available on their website to estimate costs​​. GPU Clusters are offered with state-of-the-art hardware connected over fast networks, tailored for distributed training​
