New Hardware Aims to Help Businesses Run Larger AI Models Without Relying on Cloud Services
Other World Computing has introduced OWC Stack AI, a new Thunderbolt 5 AI accelerator and storage hub designed to help businesses, developers, and researchers run larger artificial intelligence models locally on existing computers instead of relying heavily on cloud-based AI services.
The company announced the new product Thursday ahead of its first public demonstration at COMPUTEX Taipei in Taiwan.
According to OWC, the device is designed for select Windows and Linux PCs and laptops, with Mac support planned for a future release.
Local AI Processing Gains Momentum Among Businesses
As artificial intelligence adoption expands across industries in the United States and globally, businesses are increasingly facing pressure from rising cloud computing costs and concerns over sensitive data being processed offsite.
OWC says Stack AI is intended to address those concerns by allowing organizations to run larger AI models locally while extending the effective working memory available to existing hardware.
The company argues that many businesses are reaching hardware limitations as AI workloads become more demanding, particularly when using large language models, AI agents, and advanced data analysis systems.
Instead of replacing entire computer systems, OWC says the new accelerator is designed to work alongside existing PCs and laptops through a Thunderbolt 5 connection.
How OWC Stack AI Works
Expanding AI Memory Capacity
OWC Stack AI uses high-speed flash storage to expand the amount of AI working memory available to connected devices.
According to the company, this allows computers with limited onboard GPU memory to handle larger AI models and longer AI sessions without crashing or slowing down.
The device is intended to support AI inference workloads, fine-tuning tasks, and extended multi-turn AI interactions that would normally exceed the capabilities of standard laptop graphics hardware.
Thunderbolt 5 connectivity also enables faster data throughput between the computer and the external accelerator.
Focus on Privacy and Security
One of the primary selling points of Stack AI is local data processing.
OWC says organizations handling sensitive legal, medical, financial, or human resources information can process AI tasks on-premises rather than sending files to third-party cloud providers.
The company says this approach may help businesses meet privacy requirements, internal security standards, and non-disclosure agreement obligations while reducing external exposure of confidential data.
The product also targets companies concerned about the long-term operational costs associated with subscription-based AI platforms and token-based cloud billing models.
CEO Says Businesses Need More Control Over AI Infrastructure
Larry O’Connor, founder and CEO of Other World Computing, said many organizations are struggling to balance rising AI demand with infrastructure limitations.
“AI right now is forcing a lot of organizations into a corner,” O’Connor said in a statement. “Either you keep burning tokens and paying growing cloud costs every time someone asks a question, runs a workflow, or deploys an AI agent, or you try to run larger models locally and quickly discover your existing hardware cannot keep up.”
He added that the goal of Stack AI is to help businesses retain more control over cost, speed, privacy, and AI infrastructure without replacing current hardware systems.
Portable Design Targets Hybrid Work Environments
Built for Office and Remote Use
OWC says Stack AI is designed to be portable enough for use across office environments, remote work setups, and mobile workflows.
The device connects using a single Thunderbolt 5 cable and includes upgradeable storage alongside additional Thunderbolt 5 and USB ports for expanded connectivity.
The company says teams can share the device between multiple systems or move it between office and home environments as needed.
AI Software Compatibility
At launch, Stack AI will support several AI ecosystem applications and agents, including OpenClaw.
OWC says additional AI models and software integrations are expected to be added over time as the platform develops.
The company says the goal is to allow businesses and developers to integrate Stack AI into existing workflows instead of requiring entirely new software environments.
AI Hardware Market Continues to Expand
The launch of Stack AI comes as AI-focused hardware products are becoming a growing segment of the U.S. technology market.
Demand for local AI processing solutions has increased alongside concerns about cloud infrastructure costs, data privacy, latency, and reliance on third-party AI providers.
Technology companies have increasingly focused on AI accelerators, edge computing systems, and high-performance local inference hardware aimed at enterprise customers, software developers, and researchers.
Founded in 1988, Other World Computing is known for storage devices, memory products, docks, and connectivity solutions frequently used by creative professionals and business users.
OWC said Stack AI is expected to launch later this year, though pricing and final specifications have not yet been announced.
