Explainable AI or a language model: which should make a business decision?
Language models are good at writing, summarizing and answering questions in natural language. They are probabilistic: the same question can produce different answers, and the route to an answer is hard to trace. Explainable AI works a conclusion out from stated facts and shows its working, so the answer can be reproduced, checked and audited.
In plain termsOne writes a convincing answer. The other shows its working. Different jobs.
The practical difference
| Language model | Explainable, derived reasoning | |
|---|---|---|
| How an answer is produced | Generated text, one piece at a time | Computed from stated facts and evidence |
| Same question twice | May differ | Same facts, same answer |
| Can you trace it? | Rarely, in full | Back to the inputs, step by step |
| Cost behavior | Often metered per question or per token | Does not depend on how much you ask |
| Best at | Language: drafting, summarizing, exploring | Decisions that must be repeatable and defensible |
When each is the right tool
Use a language model to explore and to write. Use derived, explainable reasoning where a decision has money or regulation attached, where an auditor may ask “why”, and where the same inputs must give the same answer next week. Many teams use both: a language model as the interface, and a deterministic system as the thing that decides.
“Explainable” does not mean “no learning”
A system can use machine learning and still be explainable, if the learned part is small, bounded and visible. AnantState does exactly that: your own description of how the business normally behaves carries the model, and a small learned correction adjusts it. You can see how much the correction changed the answer, and the platform is tested against the simple guess that nothing will change. See the adaptive state engine.
What regulated teams should ask
Five questions
- Is any part of the answer generated text?
- Will the same inputs give the same conclusion tomorrow?
- Can you show the chain from the conclusion back to the facts?
- How much did the learned part change the answer, and who controls that?
- What happens to my reasoning when the vendor retires a model version?
