LAS VEGAS -- I/ONX High Performance Compute (HPC), a leading provider of heterogeneous AI systems, announced the global launch of the Symphony SixtyFour, a high-density platform designed to collapse the physical and economic footprint of AI inference and fine-tuning infrastructure. By supporting up to 64 accelerators on a single node, I/ONX eliminates the redundant Host Tax—the massive overhead in power, hardware, and licensing that negatively impacts ROI in enterprise AI.

While inference now accounts for 90% of enterprise AI workloads, enterprises are entirely limited to deploying inference on training hardware platforms. Symphony SixtyFour provides significant advantages for reduced CapEx and OpEx for inference and fine-tuning workloads. In training comparisons, the I/ONX system recovers the 30kW Host Tax typically wasted on redundant CPUs, memory, and support hardware in multi-node clusters and simplifies ongoing support tasks. For production-scale inference on alternative accelerators, the platform is even more transformative, drawing one-fourth the power of a traditional 64-device cluster—completely eliminating liquid cooling needs for inference only.

“Enterprise AI infrastructure is entering a new phase of maturity,” said I/ONX CEO Justyn Hornor. “The training-centric designs of the past served us well during the experimental phase, but they weren’t optimized for the power-constrained, production-heavy world we live in today. With Symphony SixtyFour, we’ve reimagined the stack to be more fluid and fit for purpose, allowing organizations to master massive-scale inference while finally eliminating the unnecessary infrastructure waste that has hindered ROI.”

The Symphony SixtyFour Advantage: Fit for purpose Silicon. The platform is engineered to maximize every watt and dollar for Enterprise AI.

·Eliminating the Training Host Tax: For large-scale inference and fine-tuning, Symphony SixtyFour collapses the infrastructure stack from eight nodes into one. This consolidation removes up to 30kW of wasted support power, allowing for higher compute density within existing power envelopes.
·Zero-Hop, near-Deterministic Performance: By housing 64 accelerators within a single OS instance, Symphony SixtyFour eliminates the East-West network latency.
·Heterogeneous Flexibility: Symphony SixtyFour is fully vendor-neutral and built for mixed-mode operations. Enterprises can seamlessly pair high-end GPUs (including AMD/NVIDIA) with more purpose built, low power co-processors and layer in specialized inference silicon (Axelera/FuriosaAI/Tenstorrent) future-proofing infrastructure against shifting market dynamics.
·Collapsing OpEx by simplifying the Host Tax: Beyond hardware and power, Symphony SixtyFour provides massive operational relief. By presenting a 64-device fleet through a single management environment, I/ONX collapses the Software Tax, saving enterprises up to $500,000 annually in Enterprise Operating Systems and orchestration licensing per cluster.

I/ONX accelerates the enterprise shift toward systems designed specifically for inference and fine-tuning at scale. Symphony SixtyFour is available now, enabling organizations to reclaim critical power capacity and reduce costs. I/ONX is committed to delivering high-density infrastructure required to unlock the maximum economic and operational potential of production AI.
