Cost of Predictivity
The Cost of Predictivity is the exponential increase in compute and latency required to make probabilistic AI models highly deterministic.
“The Cost of Predictivity states that squeezing 99.9% deterministic reliability out of a probabilistic AI model requires an exponential increase in architectural complexity and token spend.”
Enterprises require deterministic systems for compliance and security. However, forcing LLMs to act deterministically requires extensive guardrails, validation loops, and retries, which exponentially inflate the cost and latency per query.

Richard Ewing’s Research Thesis
Do not use LLMs for tasks that require absolute precision if traditional code can do the job. The architectural cost of forcing an LLM to be deterministic always eclipses the cost of writing standard software logic.
Why This Specification Exists
AI applications fail in enterprise settings because engineering teams drastically underestimate the cost of achieving enterprise grade reliability.
Adding more complex prompts or relying on self-correction loops.
No framework quantifying the non-linear relationship between required reliability and inference costs.
Defined the Cost of Predictivity to guide AI architectural decisions.
What Changes If You Believe This?
Use deterministic code (like regex or standard APIs) for validation, rather than asking the LLM to self-verify.
Budget for the compounding token costs of multi-stage validation pipelines.
Set realistic expectations on system latency and reliability SLAs.
Rely on deterministic governance rather than probabilistic guardrails.
