Modos de falha de IA

An AI failure mode is a repeatable way a system can produce an unacceptable result.

2 minutos de leituraÚltima atualização

Visão geral

Examples include unsupported claims, missed cases, data leakage, unsafe tool actions, and failures under changed inputs. Classifying failure modes helps teams test and address causes rather than treating every mistake as the same problem.

Principais conclusões

  • Describe triggers and consequences precisely.
  • Separate model, data, and workflow failures.
  • Match mitigations to the observed cause.

Mergulho profundo

Begin with the intended behavior and its boundaries. A wrong category, an invented citation, and a duplicated payment request require different responses. Record the trigger, observed result, affected component, and practical consequence for each failure. Distinguish model errors from system errors. A model may correctly interpret a request while a tool executes with the wrong account, a stale document supplies outdated policy, or a retry repeats a completed operation. End-to-end verification is essential when an output can change external state. Test ordinary variability and deliberate misuse separately. Formatting changes, dialects, missing data, long documents, and conflicting instructions can expose weaknesses without an adversary. Security tests add cases where an attacker tries to redirect behavior or access information. Choose controls matched to the cause: input contracts, evidence checks, permission limits, transaction identifiers, abstention, or human review. Keep failed cases for regression testing and record residual uncertainty. A mitigation that catches one example should not be described as eliminating an entire class of failures.

Visão Técnica

A fallback can create a new failure if it returns plausible but unverified content. A clear unavailable state is often more informative than an output that hides the original error.

Separate execution from a success claim

  1. Imagine an assistant saying that a file was saved after its storage tool timed out.
  2. Inspect the destination to determine whether a file exists and whether its contents match the request.
  3. If the outcome is unknown, report that state and use a safe reconciliation step before retrying. Add the timeout case to the regression suite.

This hypothetical example tests observable completion rather than the assistant’s description of it.

Custo e orçamento

Você pode fazer perguntas melhores sobre implementação antes de gastar dinheiro ou tempo.

Equipe e fluxo de trabalho

Equipes com entendimento compartilhado tomam melhores decisões sobre produtos, políticas e aprendizado.

Implementação no mundo real

Test that retries do not repeat an already completed action.

Check whether a summarizer preserves negation and uncertainty.

Riscos e guarda-corpos

Equipes diferentes podem usar o mesmo termo de maneira diferente, portanto, defina o escopo com antecedência.

Os benchmarks podem parecer fortes, enquanto o desempenho no mundo real é irregular.

Ignorar a qualidade dos dados e os planos de avaliação cria frequentemente resultados frágeis.

Roteiro de implementação

1

Comece com uma definição em linguagem simples do resultado que você precisa.

2

Escolha uma métrica de sucesso e uma condição de falha antes de testar.

3

Execute um pequeno piloto com dados representativos, não um conjunto de demonstração sofisticado.

4

Documente onde os modos de falha de IA ajudam e onde os métodos mais simples são melhores.

Perguntas frequentes

Does fixing one failed example prove the failure mode is eliminated?

No. Test meaningful variations and the underlying cause. A single successful replay is limited evidence.
