In the coming waves of “AI” innovation, the computing landscape will continue to fragment into an increasingly divergent array of hardware choices. From embedded microcontrollers to mobile devices, workstations, and accelerated compute clusters, developers will face a challenging decision: build with distinctly different “stacks” for each target or accept the deep compromises of existing cross-platform frameworks. Meanwhile, Python continues its paradoxical ascent, simultaneously becoming the lingua franca of modern computing while quietly imposing an unsustainable tax on engineering resources. What began as an elegant scripting language has evolved into a sprawling, bloated ecosystem where performance optimizations resemble engineering triage rather than sound architecture.

A Multi-Targeted Challenge is an Opportunity Rich Environment

Organizations increasingly find themselves trapped in Python’s gravitational well, with their technical debt compounding as they layer workaround upon workaround to compensate for fundamental design limitations that were never intended to support today’s computational demands. Its aging infrastructure has received decades of patchwork repairs rather than comprehensive redesign. As such, Python lumbers forward—too entrenched to abandon, too unwieldy to evolve, and too inefficient to sustain the next generation of computing challenges.

Beyond the current Python hype bubble, many cross-platform approaches force artificial trade-offs between performance, portability, and the application management experience. On one hand, platform-specific development delivers optimal performance at the cost of maintaining multiple codebases, with resulting staffing models triggering runaway maintenance costs. On the other hand, cross-platform frameworks often sacrifice native capabilities for convenience features and create a losing battle of technical debt that can mount faster than working groups can overcome.

The tension between optionality, performance and safety has led to an engineering quagmire. But what if we could re-balance these factors to maximize our advantages in each situation supported from a well-designed nexus. This solution would need the familiarity of a high-level Python-like syntax, a 20-year enterprise pedigree, and offer a unique independent streak to boot. SpeakEZ envisions a relatable technology stack that will meet this challenge and embrace the coming Cambrian Explosion of technology choices “where they live”…

SpeakEZ’s Fidelity Framework Vision

The Fidelity Framework represents our fundamentally different approach to system development at all levels. It’s based on the vaunted F# programming language which has a two decade history and has grown to already embrace two unique compiler paths. The first is of course .NET from Microsoft - which itself started more than 20 years ago, and has embraced open-source and multi-platform support of its own accord for nearly ten years. The other is an upstart, the community-led Fable compiler. It uses F#’s powerful meta-programming chops to target the daunting sprawl of web technologies, and also aspires to reach other language ecosystems. SpeakEZ’s Fidelity Framework is a third, distinct option, designed for native compilation and high performance systems operation. The architecture will span nearly the entire computing spectrum with the added bonus of maintaining the option for producing formal correctness guarantees at near “zero-cost” to the developer. This will be accomplished through several key innovations:

• MLIR/LLVM Compilation Pipeline: Direct native code generation across platforms, from embedded systems to mobile devices to hyperscale server clusters
• BAREWire Protocol: A patent-pending implementation of the BARE (Binary Application Record Encoding) standard, allowing both type-safe communication “over the wire” with efficient zero-copy memory operations for speed and security
• Safety and Speed Under Constraints: Developer-facing immutability with efficient memory implementation “under the covers” for resource constrained environments
• Olivier Actor/Agent Model: Erlang-inspired concurrency with per-process heap management that scales based on available resources. Akka.NET-inspired orchestration and supervision supports complex, reactive process management and managed interop with .NET based clusters
• A Unique Formal Methods Option: The “Fidelity” name stems from the ability to ensure adherence to semantic and safety features of F# as application code moves through the compilation pipeline. Complementing this foundation is F* (F-star), a related but distinct verification-oriented language that brings its own distinguished pedigree to the ecosystem. F* enhances Fidelity with formal verification that further strengthens the framework’s security guarantees. As SpeakEZ has pending patents in integrating these technologies, more detailed information will be forthcoming under separate cover.

Unlike frameworks that only offer performance for a single platform, or promise cross-platform capability with unwieldy compromises, Fidelity will provide true native execution across the computing spectrum without requiring separate software skill sets for each targeted platform.

MLIR/LLVM Compilation as a Cornerstone

We will leverage Multi-Level Intermediate Representation (MLIR) and LLVM build infrastructure for native compilation across computing targets. This approach aligns with the emerging industry consensus that MLIR provides the optimal funnel for targeting a variety of systems and platforms. Companies from Apple to AMD, Qualcomm, OpenAI and Tenstorrent are all investing in similar approaches for their AI accelerators and specialized hardware, underscoring the viability of this strategy.

What will distinguish Fidelity is its further embrace of delivering general-purpose systems, not just AI and machine learning workloads. Whether it’s sensor fusion “at the edge” or complex business process management in the cloud, Fidelity will deliver a compact, efficient and verifiably safe operating environment for nearly any use case.

Memory Management Across the Spectrum

The Fidelity approach to memory management will adapt with capabilities that scale based on assigned hardware resources:

• Resource-Constrained Environments: In the most limited hardware configurations, static allocation and zero-copy operations can be used exclusively, though this will be a choice rather than a limitation of the framework \

• Mid-Range Devices: Industrial and infotainment systems, such as in-vehicle head units, which often feature multi-core processors and gigabytes of RAM and sophisticated media capabilities, will leverage the Olivier actor/agent model with a scoped subset of supervision capabilities \

• High-Performance Systems: From mobile devices to workstations and clusters, the full capabilities of Olivier and Prospero will enable advanced patterns like sharding, clustering, and hierarchical supervision, including adaptive coupling with edge devices that are leveraged as “part of the cluster”. As standards such as Model Context Protocol proliferate and mature, this long-standing design pattern will come into new relevance across a wide variety of scenarios \

What will make Fidelity revolutionary is that these won’t be separate implementations—the same rock-solid foundations in the architecture will span the entire spectrum, with familiar high-level features that software engineers can implement based on available resources rather than requiring different programming models for each target.

This unified approach will enable teams to collaborate more than ever, with unprecedented sharing of code, context and knowledge between traditionally siloed working groups. A component developed for high-end systems will share design sympathies with smaller devices while only requiring minimal reshaping of the conceptual model on the part of system builders. Code written for resource-rich environments can be adapted to more constrained platforms when needed. This won’t just be better for the safety and performance of the machines these applications run on. It will also be a force multiplier where design can support new levels of alignment and productivity across working groups.

The Olivier Actor/Agent Model

Inspired by Erlang’s industrial-grade concurrency model, Olivier will provide parallelism with dedicated process-based memory spaces that scale from moderately-resourced embedded systems to high-performance clusters. Each process will maintain its own “heap”, preventing the pauses that can plague performance of monolithic garbage collection systems. Communication between processes will occur through BAREWire’s patent-pending message passing and zero-copy exchanges, ensuring safe, efficient inter-process communication without unnecessary memory overhead.

Importantly, Olivier’s process model will be designed to adapt to the available resources rather than requiring a specific configuration. A tablet with multiple processor cores and gigabytes of RAM will take advantage of Olivier, with a narrowed scope, despite being classified in traditional terms as a “handheld” device. And when deployed in the data center across CPU and GPU clusters, Olivier and Prospero will take center stage.

Prospero: Orchestrating the Process Ecosystem

While Olivier will define the actor/agent model, Prospero will provide the management plane that handles orchestration, supervision, and actor livecycles. Inspired by Akka.NET’s actor supervision strategies, Prospero will enable sophisticated patterns like clustering and sharding across multi-node environments. And due to its mechanical sympathy with Akka.NET we will have designs to coordinate with and even “hand over the reins” to a .NET based Akka cluster when desired.

Multi-Targeting in Action

The true power of the Fidelity Framework will manifest when targeting diverse platforms from a unified design. Fidelity will offer direct deployment capabilities that no other platform in the world currently supports:

• Micro-controllers On The Metal: From the tiny ESP32 to high end SoCs, Fidelity will deliver speed equal to C and C++ embedded code in a developer-friendly Python-like syntax, all with higher memory safety and compute reliability guarantees
• True Native iOS Applications: Unlike frameworks that compile to intermediate representations or require runtime bloat, Fidelity will generate native ARM64 binaries that integrate directly with iOS delivery requirements
• True Native Android Applications: Through its MLIR/LLVM pipeline, Fidelity will create genuine native Android applications without the overhead of runtime interpreters, connecting directly to Android’s NativeActivity infrastructure
• Industrial and Complex Embedded Systems: Dedicated control systems will leverage the full power of the Fidelity framework through hardware implementations on FPGAs and ASICs, using industry-standard HDLs with a compilation flow that incorporates MLIR and LLVM for efficient hardware/software co-design and optimization
• AI Accelerators: Fidelity’s MLIR/LLVM approach will align with hardware like Tenstorrent’s AI processors, AMD’s Ryzen AI NPUs, and emerging heterogeneous computing architectures
• Server-Side Processing: The same code design patterns will scale to high-performance clusters, leveraging Prospero’s sophisticated supervision and orchestration capabilities across multi-region deployments

An F# codebase in this framework would have the ability to target these environments without requiring developers to learn multiple programming paradigms. It still remains that the developer must understand the system they’re targeting, but the “double translation” of bringing that frame into a new language ecosystem has been removed with Fidelity. This world-first memory management and systems design approach will be adapted to each platform, offering a consistent Python-like programming experience with greater compute precision and memory safety to go with dramatically improved performance.

Emerging Hardware Architectures

Fidelity’s compilation strategy will position it uniquely for the ever-growing diversification of computing hardware. The industry is converging on MLIR/LLVM as the preferred path for heterogeneous compute:

• Tenstorrent’s TT-Forge and Tensix uses MLIR to optimize workloads for their AI hardware
• Qualcomm’s ELD provides an open-source embedded linker tool as part of their LLVM toolchain
• AMD’s Peano compiler for Ryzen AI NPUs leverages LLVM to target their XDNA and XDNA2 accelerators
• OpenAI’s Triton Project is a new MLIR lowering strategy targeting NVidia and AMD GPU hardware including custom kernel development beyond CUDA and ROCm

Fidelity’s approach has been designed with this diversification in mind. By embracing MLIR as its compilation “funnel”, Fidelity applications will naturally extend to leverage these and other emerging accelerators without fundamental changes to the programming model.

This forward-looking architecture will ensure that investments in Fidelity applications are protected against hard pivots in hardware, allowing developers to focus on application logic rather than suffering “jank” due to shifts in the data center provisioning. And managers will breathe easy knowing they can quickly re-deploy to new architectures as needed, and never again be burdened with the dread of vendor lock-in.

A Clear Path Forward

For developers grappling with the increasing sprawl of computing platforms, SpeakEZ’s Fidelity Framework will offer a mature, curated evolutionary path with familiar coding conventions:

• Write applications in F# with a safe, precise Python-like functional programming model
• Target the entire computing spectrum through the MLIR/LLVM compiler ecosystem
• Use BAREWire’s zero-copy mechanics along with concise static allocations as the default approach for efficient memory management
• Leverage the Olivier Actor/Agent model for “heap” management and high-performance concurrency across the resource spectrum

Unlike any other framework today, Fidelity will enable true native development across servers, handhelds, micro-controllers - the full gamut of computing hardware. This will not be achieved through lowest-common-denominator abstractions, but through a sophisticated architecture that provides a light approach to adapting to the capabilities of each target while maintaining a consistent and rewarding developer experience.

For general-purpose applications .NET remains a solid option for F#. Fidelity will distinguish itself by offering a solution for scenarios where performance, resource utilization, hardware acceleration, and formal verification make a difference for fast, trusted, secure-by-default, and highly resilient computing environments.

For all of its apparent success, Python has become a victim of its own popularity. What began as an elegant solution has evolved into a rushed patchwork of compromises, with each new bolted-on feature and runtime library further straining its aging foundation. Companies across the AI landscape are recognizing the unsustainable technical debt and computational cost accumulating within Python-centric infrastructures.

In contrast, Fidelity’s unique implementation of F# offers a transformational alternative. It’s built on sound computer science principles with high-performance at its foundations. This implementation provides the familiar functional experience developers value while delivering unprecedented precision, safety, and speed across traditionally incompatible computing boundaries. The approach enables software teams to extend their impact beyond what conventional frameworks permit, eliminating the forced trade-offs that have become an assumed burden of cross-platform development.

With the Fidelity framework, developers deliver value on a trustworthy foundation that scales elegantly from edge devices to high-performance clusters, all while maintaining the accessibility and expressiveness that made Python attractive in the first place. SpeakEZ envisions a computing landscape where boundaries dissolve and possibilities expand—where developers create freely across the full spectrum of devices without sacrificing performance or security. Together, we’re building more than just a framework; we’re cultivating a future where computational creativity flourishes uninhibited by yesterday’s limitations, empowering the next generation of innovations that will transform how humanity interacts with technology.
