Could you build this?
No Measuring sub-microsecond epistemic uncertainty from LLM inference passes in Rust requires specialized mathematical research and high-performance computing expertise.
What it would actually take: Implemented in low-level Rust with optimized SIMD/GPU tensor bindings to evaluate uncertainty metrics (such as semantic entropy, token logit variance, or conformal prediction scores) directly on logits or hidden states during generation. The hard part is achieving sub-microsecond latency, which demands zero-copy memory access, lock-free concurrency, and deep theoretical understanding of Bayesian deep learning and uncertainty quantification. Requires machine learning systems researchers with strong Rust systems-programming experience.
