Nobody Wins the Model War. Together AI Just Raised $800M Betting on It.
The smart money isn't picking a model. It's selling the rails every model runs on.
A frontier model can quietly eat your entire margin. Together AI just raised $800 million on the bet that companies are finally done paying that bill.
On July 1, Together AI closed an $800 million Series C at an $8.3 billion post-money valuation, led by Aramco Ventures, the venture arm of Saudi Aramco, with Nvidia, Vista Equity Partners, General Catalyst, and Emergence Capital joining. Per TechCrunch, that’s up from a $3.3 billion valuation just 16 months ago. The company says annual bookings crossed $1.15 billion last quarter and that usage of open models on its platform tripled over the past year. Those last two are company-reported, so hold them a little loosely.
Here’s the business in plain English. Together AI is an “AI neocloud.” It rents out GPU clusters, and more importantly, it layers its own software on top that it says cuts the cost of running popular open-weight models like DeepSeek and Nemotron by up to 80%. Customers like Cursor and Cognition run those open models instead of pricey closed APIs to protect their margins. Together sells the cheaper road.
Now apply Commoditize Your Complement, one of the models in my book.
A business wins when the thing sitting right next to its product gets cheap and abundant. Microsoft wanted PC hardware dirt cheap because it sold the operating system on top. The cheaper the complement, the more demand pools into you. Together AI’s complement is the model itself. Every time an open-weight model gets good enough and nearly free, the valuable question shifts from “which model?” to “where do I run it cheaply?” Together isn’t betting OpenAI or Anthropic loses. It’s betting the model layer keeps commoditizing, and that the neutral place to run any of them is where the durable margin sits. The pick-and-shovel version is “in a gold rush, sell shovels.” The sharper version is “make sure the gold keeps getting cheaper, so everyone needs more shovels.”
My take? Read the cap table. Aramco leading this has almost nothing to do with oil and everything to do with a sovereign fund deciding that compute and energy, not any single model, are where value sits for the next decade. Nvidia’s in because every workload Together runs, whatever model’s on top, still runs on Nvidia chips underneath. When the strategics quietly agree the money is under the models, that’s worth noticing.
The loudest question in AI is “which model wins?” For builders, that’s the wrong question. Ask “what stays valuable no matter which model wins?” The answer is usually the infrastructure and the rails. It’s the same instinct behind what we build at /mkt: the durable spot in any market is the regulated infrastructure everyone has to route through, not the one asset riding on top.
One honest caveat: $8.3 billion prices in a lot going right. The hyperscalers and Nvidia itself can lean on independent neoclouds, and cheap capacity can tip into a brutal price war. Selling shovels only works while the digging still pays. That’s the risk to watch.
