Comparison
just-eval vs hallucination-index
Verdict
Pick just-eval if just-eval provides a straightforward GPT-based framework for evaluating LLMs across multiple dimensions with clear outputs; pick hallucination-index if hallucination-Index helps users identify LLMs with the lowest propensity for factual errors across varying context lengths and source types.

Choose just-eval if…
- Tags unique to just-eval: evaluation, gpt4, llm, llm-eval.
- When your team requires an in-depth yet interpretable evaluation of LLM performance, focusing on various aspects.
When NOT to use just-eval
- Avoid if direct integration with competing API services is needed as just-eval focuses solely on OpenAI API key configuration.
- Not suitable when your project demands a custom evaluation framework that extends beyond simple GPT-based assessments.
Choose hallucination-index if…
- Tags unique to hallucination-index: hallucinations, large-language-models, openai, rag.
- Use when you need to ensure accuracy in short-context tasks, as it tests models like Chain-of-Note prompting techniques specifically for such scenarios.
- More GitHub stars (115 vs 90) - visibility, not fit.
When NOT to use hallucination-index
- Avoid using Hallucination-Index when your application requires real-time evaluation of hallucinations, as it focuses on predefined tests rather than live model performance.
- Do not rely solely on this index if your primary concern is the latest updates to LLM models; its data might not reflect recent improvements in models or the introduction of new ones.
