Together AI

Overview

Together AI is a cloud inference platform optimized for running open-source large language models at scale with industry-leading speed and cost efficiency. Founded by researchers from Stanford, Meta, and Google, Together AI provides API access to dozens of leading open models including Llama, Mistral, Qwen, and DeepSeek, along with image generation models like Stable Diffusion and FLUX. The platform uses advanced optimizations including FlashAttention-2, continuous batching, speculative decoding, and tensor parallelism to achieve 2-5x faster inference compared to standard deployments with typical latency of 50-200ms time to first token and 30-80 tokens per second generation speed. Together AI's pricing is highly competitive, often 50-80% cheaper than OpenAI while providing similar quality with open models like Llama 3.1 70B at $0.88/$0.88 per million tokens. The service also offers fine-tuning capabilities, custom model deployment, and dedicated capacity for enterprise users requiring guaranteed availability and performance. With a focus on open-source models, transparent pricing, and both cloud and self-hosted options, Together AI appeals to developers seeking cost-effective alternatives to proprietary LLM APIs.
