# Together AI secures $800M Series C at $8.3B valuation, annual bookings exceed $1.15B

> Together AI has closed an 800 million dollar Series C at an 8.3 billion dollar valuation, led by Aramco Ventures, with annual bookings the company says now exceed 1.15 billion dollars. The pitch is straightforward: open-source models running on Together's infrastructure as a cheaper, more controllable alternative to closed proprietary systems. That positioning is resonating as enterprises grow cost-sensitive and wary of lock-in. Together provides the training and inference plumbing that lets companies deploy open models at scale, and the bookings figure suggests real commercial traction rather than speculative interest alone. The round underscores a broader shift in the market, where open-weight models have become good enough that the surrounding infrastructure, not just the model itself, is where a lot of the money and differentiation now sit.
