Hebrew LLM evaluation

Hebrew LLM Evaluation for Production AI Systems

Evaluate Hebrew model outputs against task-specific criteria including correctness, instruction compliance, language quality, localization, factuality, refusal behavior, tone, safety, and consistency.

Buyer problem

Models can appear fluent while producing incorrect morphology, unnatural register, mixed-direction formatting errors, unsupported claims, weak refusals, or inconsistent behavior across semantically equivalent prompts.

Suitable use cases

  • Hebrew chatbot and assistant evaluation
  • Pre-release model comparison
  • Regression testing after prompt or model changes
  • Domain-specific factuality and terminology review
  • Safety, refusal, and instruction-compliance testing

Inputs required from the client

  • Model access or exported outputs
  • Target use cases and user groups
  • Policies, expected behavior, and severity definitions
  • Domains and terminology that require specialist review
  • Desired scoring scale and reporting format

Evaluation dimensions

  • Native Hebrew fluency
  • Morphology and agreement
  • Hebrew-English code-switching
  • Right-to-left formatting
  • Domain terminology
  • Instruction following
  • Factuality and unsupported claims
  • Safety and policy compliance
  • Tone and cultural appropriateness
  • Consistency across prompt variants

Method and workflow

A pilot rubric and test set are created from the intended use cases. Outputs are evaluated, errors are assigned to a defined taxonomy, severe failures are escalated, and the rubric is revised before a larger evaluation run.

Deliverables

  • Evaluation rubric
  • Test-case set
  • Annotated model outputs
  • Error taxonomy
  • Quantitative score summary
  • High-severity failure examples
  • Remediation recommendations

Acceptance criteria and quality metrics

Metrics may include pass rate, severity-weighted failure rate, consistency across variants, factuality rate, refusal quality, language-quality score, and reviewer agreement.

Data-handling considerations

Evaluation can use non-confidential prompt sets, exported model outputs, or secure client-controlled environments. Sensitive production data is not requested through the public form.

A pilot typically covers a defined use case, a small test-case set, an agreed rubric, annotated outputs, and an initial failure analysis.
