Together AI

Together AI is a cloud platform that provides API access to a wide selection of open-source models (Llama, Mistral, Qwen, DBRX, and more) with competitive pricing, fast inference, and fine-tuning capabilities. It offers both serverless inference and dedicated deployments for teams running open models in production. Developers and enterprises who want the flexibility of open-source models without managing GPU infrastructure use Together AI. Its fine-tuning service lets teams adapt models to domain-specific data and deploy custom models through the same API interface. Together AI's positioning in the open-source model serving market gives teams an alternative to proprietary model APIs: using the same interface format as OpenAI but with open models that can be customized, inspected, and controlled. Its competitive pricing often significantly undercuts equivalent proprietary model API costs.
