What is Together AI?
A machine learning team at a Series A startup needs to deploy a fine-tuned LLaMA model for their production chatbot — but building and managing the GPU infrastructure to serve inference at scale would consume three months of engineering time before a single customer query is processed. Together AI is the platform that eliminates that infrastructure build. Together AI is a cloud AI infrastructure platform providing ultra-fast LLM inference, custom model fine-tuning, and scalable GPU cluster access through a unified API — enabling developers and research teams to train, deploy, and serve large language models without managing underlying GPU infrastructure. The platform supports dozens of open-source models including Llama 3, Mistral, DBRX, and models from the RedPajama project, with inference speeds that benchmark among the fastest available for open-weight models at equivalent hardware configurations. Together AI's inference API delivers output tokens at speeds that are consistently faster than comparable API providers on open-source models — independently benchmarked at token generation rates that make real-time conversational applications viable where slower inference would introduce perceptible response latency. For startups and research teams whose use cases require model customization, the fine-tuning pipeline accepts dataset uploads in standard formats and produces a deployment-ready custom model checkpoint without requiring distributed training code or infrastructure configuration. Together AI is not suited for teams whose applications require proprietary frontier models — GPT-4o or Claude 3.5 — as primary inference targets; the platform focuses on open-weight models rather than closed API models from OpenAI or Anthropic. Organizations running primarily closed-model workloads should evaluate Together AI specifically for the subset of use cases where open-weight model performance is adequate for their requirements.
Together AI is a freemium AI infrastructure platform delivering ultra-fast LLM inference, custom model fine-tuning, and scalable GPU clusters for developers and research teams at production scale.
Together AI is widely used by professionals, developers, marketers, and creators to enhance their daily work and improve efficiency.

Final Verdict
Compared to self-hosting open-source LLM inference on provisioned GPU instances, Together AI reduces time-to-production from weeks of infrastructure configuration to hours of API integration — with independently benchmarked inference speeds that typically exceed self-hosted performance on equivalent compute because of Together AI's specialized inference optimization layer. The platform's primary limitation is its open-weight model focus, which means teams whose production applications require GPT-4o or Claude 3.5-class closed model capability must maintain a separate API relationship with those providers alongside Together AI.
