Together AI
Open-model GPU cloud + fast inference for open-source LLMs.
Together AI provides GPU clusters plus an optimized inference/training platform specializing in open-source and open-weight models (Llama, DeepSeek, Qwen, etc.). It combines a neocloud (reserved Nvidia clusters) with a high-performance inference API and research on efficient kernels/attention. In 2025 it raised a large round at multi-billion valuation as demand for open-model hosting grew.
