Choose langevals if…
- Tags unique to langevals: evaluation, guardrails, llm.
- When you need a singular point of access to multiple LLM evaluation tools
- More recently updated (last pushed Feb 15, 2026).
When NOT to use langevals
- If you prefer not having a dependency on LangEvals after it has been moved into the LangWatch monorepo, opting for directly managing individual evaluators could be a better option
- When needing to customize evaluation processes extensively beyond what the provided standard interface allows
Choose hallucination-index if…
- Tags unique to hallucination-index: hallucinations, large-language-models, llm-evaluation, 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 72) - 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.
