IBM and Together AI sign $240 mn deal to build NVIDIA B300 inference cluster. Together AI will use the infrastructure to increase inference capacity and bring down the cost of serving open-source models to enterprise customers. AUGUST 11, 2026, 7:23 PM IBM and Together AI have signed a multi-year $240 million agreement to deploy a large cluster of NVIDIA HGX B300 systems on IBM Cloud, with the infrastructure expected to be available in the first quarter of 2027. Together AI will use the cluster to provide inference for open-source AI models. The deployment will be the first dedicated large-scale inference cluster on IBM Cloud using NVIDIA HGX B300 systems and NVIDIA Spectrum-X Ethernet networking. The companies said the infrastructure will help Together AI increase inference capacity while reducing the cost of serving AI models to enterprise customers. "Enterprises want the performance of the best frontier models without the closed-model price tag, and that only works if the infrastructure underneath is fast and reliable at scale," said Vipul Ved Prakash, CEO of Together AI. "Working alongside IBM with NVIDIA gives us that foundation. This cluster lets us bring production-grade inference to more companies, faster, and it's a big step in our push to make open-source AI the obvious choice for enterprises," he added. Together AI said its inference business now processes 400 trillion tokens a month. The company raised $800 million in a Series C round at an $8.3 billion valuation, with the funding going towards its AI Native Cloud. Its platform covers inference, model training, fine-tuning and agentic workflows. The company has positioned open-source models as an alternative to closed AI systems, with developers able to build applications using modular model and infrastructure stacks. Together AI selected IBM and NVIDIA based on their infrastructure roadmaps and ability to provide GPU capacity at the pace required for its expansion. The companies also pointed to the cost of serving tokens as a key consideration. The cluster will use NVIDIA HGX B300 systems connected through NVIDIA Spectrum-X Ethernet networking. NVIDIA said its B300 platform can deliver 30 times more AI factory output than prior generations. IBM said the infrastructure will also give Together AI a path into the enterprise market by combining its inference platform with IBM Cloud infrastructure. "Enterprises are in a race to adopt agentic AI at scale to drive real business outcomes," said Alan Peacock, General Manager of IBM Cloud. "IBM and NVIDIA are delivering scalable, economical, enterprise-grade AI infrastructure that can help Together AI accelerate innovation for the next generation of AI infrastructure." The deal also expands an existing collaboration between IBM and NVIDIA. The companies have been working across GPU-native data analytics, unstructured data extraction, on-premises and cloud infrastructure, and consulting services. Dion Harris, Senior Director of HPC and AI Infrastructure Solutions at NVIDIA, said the infrastructure would help enterprises deploy open-source AI for real-time services. "AI factories are becoming essential enterprise infrastructure - like electricity and telecommunications - turning compute and data into intelligence," Harris said. Your reaction Discussion.

IBM and Together AI Sign Multi-Year Agreement to Scale Open-Source AI Inference with NVIDIA AI Infrastructure on IBM Cloud. Aug 11, 2026, 08:00 ET First large-scale inference cluster with Together AI on IBM Cloud using NVIDIA HGX B300 systems to help enterprises run AI workloads, designed for fast and efficient production ARMONK, N.Y. and SAN FRANCISCO, Aug. 11, 2026 /PRNewswire/ - IBM (NYSE: IBM) announced a collaboration with Together AI to deliver IBM and NVIDIA AI infrastructure. Under a multi-year $240M agreement between IBM and Together AI, IBM is positioned to deploy a large cluster of NVIDIA HGX B300 systems on IBM Cloud with expected availability in Q1 2027. Together AI will use this cluster to provide open-source model inference. This deployment is the first dedicated, large-scale cluster built for inference on IBM Cloud using HGX B300 systems and NVIDIA Spectrum-X(TM) Ethernet networking. According to NVIDIA, it is built to deliver 30x more AI factory output compared to prior generations. This collaboration aims to enable Together AI to deliver better performance and token economics to enterprises as they look to efficiently scale their AI deployments. Together AI is built on the principle that open-source models are essential for the future of AI and developers should be able to build using open, modular stacks. The company recently raised an $800M Series C financing round at an $8.3B valuation to expand its AI Native Cloud and its platform spans capabilities across inference, training, fine tuning, and agentic workflows. The company reports that it has seen significant momentum for its inference product, now serving 400 trillion tokens monthly. Together AI selected IBM with NVIDIA because of their innovative product roadmaps and their ability to deliver GPU capacity at the pace required for rapid AI scaling and lowest token cost. Building on IBM's expertise in delivering enterprise-grade cloud capabilities, this collaboration aims to help Together AI to continue its expansion into the enterprise space while making open-source AI more accessible to developers and enterprises around the world. "Enterprises want the performance of the best frontier models without the closed-model price tag, and that only works if the infrastructure underneath is fast and reliable at scale," said Vipul Ved Prakash, CEO at Together AI. "Working alongside IBM with NVIDIA gives us that foundation. This cluster lets us bring production-grade inference to more companies, faster, and it's a big step in our push to make open-source AI the obvious choice for enterprises." IBM and NVIDIA Expand Collaboration to Power the Next Wave of AI Innovation "Enterprises are in a race to adopt agentic AI at scale to drive real business outcomes," said Alan Peacock, General Manager of IBM Cloud. "IBM and NVIDIA are delivering scalable, economical, enterprise-grade AI infrastructure that can help Together AI accelerate innovation for the next generation of AI infrastructure." "AI factories are becoming essential enterprise infrastructure - like electricity and telecommunications - turning compute and data into intelligence," said Dion Harris, Senior Director, HPC and AI Infrastructure Solutions, NVIDIA. "With NVIDIA HGX B300 systems and NVIDIA Spectrum-X Ethernet networking on IBM Cloud, IBM and Together AI will deliver an accelerated computing platform to help enterprises deploy open-source AI with the performance, efficiency and scale required for real-time AI services." This work is the latest example of a larger collaboration between IBM and NVIDIA, who continue to work together to advance AI across infrastructure and software, to deliver performance and efficiency for enterprise and startup clients.
