UAF fundamentally reimagines the software compilation pipeline by substituting traditional syntax parsers with a neural frontend trained on logic-to-bytecode mappings.
The Intent Translator
The neural frontend is an LLM specifically fine-tuned on a synthetic dataset of millions of (prompt → WebAssembly) pairs. Unlike traditional language models trained on GitHub code, this model learns the mathematical relationship between intent and executable binary states.
By training on direct logic-to-bytecode paths, the model bypasses the entire syntax layer. It doesn't "write code" in Python or C++—it configures processor states. Variable names, indentation, semicolons, and other human constructs are completely absent from its learned representations.
The base architecture is a Llama-3 class transformer (7B-13B parameters) optimized for speed. Larger models (70B+) are too slow for real-time generation. The fine-tuning uses LoRA (Low-Rank Adaptation) for efficient training on consumer hardware.
The Portable Binary Format
The output is WebAssembly (Wasm) bytecode—a compact, type-safe, stack-based virtual machine format. Wasm was designed by Mozilla, Google, Microsoft, and Apple as a compilation target for the web, but it's fundamentally a universal binary format that runs anywhere.
Unlike x86 or ARM machine code which is platform-specific, Wasm is an intermediate representation. It's closer to LLVM IR than to raw assembly, which gives us portability without sacrificing performance. Modern JIT compilers can translate Wasm to native code with near-zero overhead.
The bytecode is mathematically precise. Every instruction has explicit types (i32, i64, f32, f64), memory operations are bounds-checked, and the control flow is structured (no arbitrary jumps). This makes it both secure and analyzable.
Security Through Sandboxing
The Guardian is a designated runtime that instantiates Wasm modules in a secure sandbox. It translates the universal bytecode to your platform's native machine code (ARM, x86, RISC-V) while enforcing strict capability-based security.
By default, Wasm modules have zero access to the outside world. They can't read files, make network requests, or call system APIs unless explicitly granted capabilities through WASI (WebAssembly System Interface). This is security by isolation, not by human code review.
The Guardian also implements resource limits: maximum memory allocation, execution time limits, and CPU throttling. If the AI generates an infinite loop or fork bomb, it's caught and killed before consuming system resources.
For enterprise deployments, an optional Guardian AI classifier can pre-scan generated bytecode for suspicious patterns (recursive explosions, tight loops without exit conditions) before execution.
