Together AI raises 800 million dollars at an 8.3 billion dollar valuation

Together AI's valuation more than doubling in sixteen months is really a story about how much money there still is chasing anyone who can rent out GPU capacity for open-source models, not about Together's product specifically. Aramco Ventures leading the round is notable too, since sovereign wealth capital is increasingly treating AI infrastructure like the oil infrastructure it already knows how to fund. The bigger picture is that open-source model hosting has quietly become one of the most reliable businesses in AI, safer than betting on any single model staying ahead.
