July 2, 2026, (Inside AI) — Together AI, a startup enabling companies to train and run AI workloads on open models, has secured $800 million in a new funding round. The investment, led by Aramco Ventures, more than doubles the company’s valuation to $8.3 billion.
The round underscores surging investor appetite for infrastructure that supports open-source AI, as enterprises seek alternatives to proprietary systems. Together AI’s platform allows users to leverage models like DeepSeek, MiniMax, and Kimi at a fraction of the cost of closed competitors.
Founded in 2022, the company has positioned itself at the intersection of two major trends: the commoditization of large language models and the growing demand for cost-efficient AI compute. By focusing on open models, Together AI taps into a developer community wary of vendor lock-in.
The funding arrives amid a broader recalibration in AI investment. While mega-rounds for foundation model companies have slowed, infrastructure and tooling startups continue to attract capital. Together AI’s raise follows significant rounds for cloud GPU providers and model deployment platforms.

Aramco Ventures’ lead role signals strategic interest from energy-sector players in AI infrastructure, likely tied to the massive power demands of data centers. The Saudi-backed fund has been expanding its tech portfolio, betting on AI’s long-term compute needs.
Together AI’s platform abstracts away the complexity of distributed training and inference, offering a managed service that competes with hyperscalers. Its pitch: run state-of-the-art open models without the overhead of managing clusters or negotiating proprietary licenses.
Industry observers note that the valuation jump—from roughly $3.5 billion to $8.3 billion—reflects a premium for neutrality. As enterprises adopt multi-model strategies, a platform that supports any open model gains leverage over single-model vendors.
Yet the open model landscape is fraught with legal and performance uncertainties. Some models, like DeepSeek, have faced scrutiny over data provenance and benchmark gaming. Together AI’s success hinges on the continued viability and improvement of these community-driven models.
The company has not disclosed revenue figures, but its rapid valuation growth suggests strong traction. Competitors include Anyscale, Modal, and cloud-native services from Google Cloud and Amazon Web Services.
In a statement, Together AI emphasized its mission to democratize AI by making open models accessible and affordable. No direct quotes from executives were provided in the original report.

The round also included participation from existing investors, though their names were not disclosed. The company plans to use the funds to scale its infrastructure and expand its model library.
As the AI industry matures, the battle between open and closed ecosystems intensifies. Together AI’s latest funding round positions it as a key player in the open-source AI infrastructure space, with the backing to challenge established cloud providers.
