Simplifying the AI stack: The key to scalable, portable intelligence from cloud to edge
Presented by Arm
A simpler software stack is the key to portable, scalable AI in the cloud and edge.
AI now powers real-world applications, but fragmented software stacks are holding it back. Developers routinely rebuild the same models for different hardware targets, losing time gluing code instead of shipping features. The good news is that a shift is happening. Unified toolchains and optimized libraries make it possible to deploy models across platforms without sacrificing performance.
Yet one crucial hurdle remains: software complexity. Disparate tools, hardware-specific optimizations, and layered tech stacks continue to hinder progress. To unlock the next wave of AI innovation, the industry must move decisively away from silo development and towards streamlined, end-to-end platforms.
This transformation is already taking shape. Major cloud providers, edge platform vendors, and open source communities are coming together in unified toolchains that simplify development and accelerate deployment, from cloud to edge. In this article, we explore why simplification is key to scalable AI, what’s driving this momentum, and how next-generation platforms are turning that vision into real-world results.
The bottleneck: fragmentation, complexity and inefficiency
The problem isn’t just hardware variation; it’s duplication of effort within frameworks and goals that slows time-to-value.
Various hardware targets: GPUs, NPUs, CPU-only devices, mobile SoCs, and custom accelerators.
Tooling and framework fragmentation: TensorFlow, PyTorch, ONNX, MediaPipe and others.
Edge constraints: Devices require real-time, low-power performance with minimal overhead.
According to Gartner researchThese mismatches create a significant hurdle: more than 60% of AI initiatives stall before production, driven by integration complexity and performance variability.
What software simplification looks like
Simplification boils down to five steps that reduce the costs and risks of reengineering:
Cross-platform abstraction layers that minimize re-engineering when porting models.
Performance-tuned libraries integrated into major ML frameworks.
Uniform architectural designs that scale from data center to mobile.
Open standards and runtimes (e.g. ONNX, MLIR) reducing lock-in and improving compatibility.
Developer-first ecosystems with an emphasis on speed, reproducibility and scalability.
These shifts make AI more accessible, especially for startups and academic teams that previously lacked the resources for custom optimization. Projects like Hugging Face’s Optimum and MLPerf benchmarks also help standardize and validate cross-hardware performance.
Ecosystem momentum and real-world signals Simplification is no longer ambitious; it’s happening now. Across the industry, software considerations influence decisions at the IP and silicon design level, resulting in solutions that are production-ready from day one. Major ecosystem players are driving this shift by aligning hardware and software development efforts, creating tighter integration across the stack.
A key catalyst is the rapid rise of edge inference, where AI models are deployed directly on devices rather than in the cloud. This has intensified the demand for streamlined software stacks that support end-to-end optimization, from silicon to system to application. Companies like Arm are responding by enabling tighter coupling between their computing platforms and software toolchains, allowing developers to accelerate time-to-deployment without sacrificing performance or portability. The emergence of multimodal and general foundation models (e.g. LLaMA, Gemini, Claude) has also increased the urgency. These models require flexible runtimes that can scale across cloud and edge environments. AI agents, which communicate, adapt, and perform tasks autonomously, increase the need for highly efficient, cross-platform software.
MLPerf Inference v3.1 included more than 13,500 performance results from 26 submitters, validating benchmarking of AI workloads across multiple platforms. The results included both data center and edge devices, demonstrating the diversity of optimized deployments now being tested and shared.
Taken together, these signals make it clear that market demands and incentives are focused on a common set of priorities, including maximizing performance per watt, ensuring portability, minimizing latency, and delivering security and consistency at scale.
What needs to be done for successful simplification
To deliver on the promise of simplified AI platforms, several things need to happen:
Strong hardware/software co-design: hardware features visible in software frameworks (e.g., matrix multipliers, accelerator instructions), and conversely, software designed to take advantage of the underlying hardware.
Consistent, robust toolchains and libraries: Developers need reliable, well-documented libraries that work across devices. Performance portability is only useful if the tools are stable and well supported.
Open ecosystem: Hardware vendors, software framework maintainers, and model developers need to work together. Standards and shared projects help avoid having to reinvent the wheel for every new device or use case.
Abstractions that do not cloud performance: While high-level abstractions help developers, they should still enable tuning or visibility where necessary. The right balance between abstraction and control is crucial.
Security, privacy and trust built in: Especially as more and more computing power shifts to devices (edge/mobile), issues such as data protection, secure execution, model integrity and privacy are important.
Poor as an example of ecosystem-led simplification
Simplifying AI at scale now depends on system-wide design, where silicon, software, and developer tools evolve in tandem. This approach ensures that AI workloads can run efficiently in diverse environments, from cloud inference clusters to edge devices with limited battery capacity. It also reduces the overhead of custom optimization, making it easier to bring new products to market faster. Arm (Nasdaq:Arm) is advancing this model with a platform-centric focus that pushes hardware-software optimizations across the software stack. Bee COMPUTEX2025Arm demonstrated how the latest Arm9 CPUs, combined with AI-specific ISA extensions and the Kleidi libraries, enable tighter integration with commonly used frameworks such as PyTorch, ExecuTorch, ONNX Runtime and MediaPipe. This alignment reduces the need for custom kernels or hand-tuned operators, allowing developers to unlock hardware performance without giving up familiar toolchains.
The real world implications are significant. In the data center, Arm-based platforms deliver improved performance per watt, critical for sustainably scaling AI workloads. On consumer devices, these optimizations enable highly responsive user experiences and background information that are always on, yet power efficient.
More broadly, the industry is coalescing around simplification as a design imperative, embedding AI support directly into hardware roadmaps, optimizing software portability, and standardizing support for mainstream AI runtimes. Arm’s approach illustrates how deep integration within the compute stack can make scalable AI a practical reality.
Market validation and momentum
By 2025, nearly half of the computing power sent to large hyperscalers will run on Arm-based architecturesa milestone that underlines a significant shift in cloud infrastructure. As AI workloads become more intensive, cloud providers are prioritizing architectures that deliver superior performance per watt and support seamless software portability. This evolution marks a strategic pivot toward an energy-efficient, scalable infrastructure optimized for the performance and demands of modern AI.
At the edge, Arm-compatible inference engines enable real-time experiences, like live translation and always-on voice assistants, on battery-powered devices. These improvements bring powerful AI capabilities directly to users without sacrificing energy efficiency.
Developer momentum is also accelerating. In a recent collaboration, GitHub and Arm introduced native Arm Linux and Windows runners for GitHub Actions, streamlining CI workflows for Arm-based platforms. These tools lower the barrier to entry for developers and enable more efficient, cross-platform development at scale.
What comes next
Simplification does not mean removing complexity completely; it means we need to manage it in a way that enables innovation. As the AI stack stabilizes, the winners will be those that deliver seamless performance in a fragmented landscape.
From a forward-looking perspective, you can expect the following:
Benchmarks as guardrails: MLPerf + OSS suites guide where to optimize next.
More upstream, fewer forks: Hardware features end up in regular tools, not custom branches.
Convergence of research + production: Faster transfer from paper to product via shared runtimes.
Conclusion
The next phase of AI isn’t about exotic hardware; it’s also about software that travels well. When the same model runs efficiently across cloud, client, and edge, teams ship faster and spend less time rebuilding the stack.
Ecosystem-wide simplification, not branded slogans, will separate the winners. The practical playbook is clear: unify platforms, upstream optimizations and measure with open benchmarks. Learn how to weaponize AI software platforms make this future possible – efficiently, safely and at scale.
