Context7
Feeds AI the latest docs for libraries and frameworks before it answers, so code it writes does not use outdated, removed functions.
Description from the maker (original English)
Generate QA datasets & evaluate RAG systems with failure diagnosis. Any LLM.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.
OPENAI_API_KEY, ANTHROPIC_API_KEYValues marked secret are keys to your account. Never share them or paste them into a chat.

Generate QA datasets & evaluate RAG systems in 2 commands
🔒 Privacy-First • ⚡ Lightning Fast • 🤖 Any LLM • 🏠 Local or Cloud • 🌍 Multilingual

# Step 1: Generate QA pairs from your docs
ragscore generate docs/
ragscore evaluate http://localhost:8000/query
That's it. Get accuracy scores and incorrect QA pairs instantly.
============================================================
✅ EXCELLENT: 85/100 correct (85.0%) Average Score: 4.20/5.0 ============================================================
❌ 15 Incorrect Pairs:
pip install ragscore # Core (works with Ollama)
pip install "ragscore[openai]" # + OpenAI support pip install "ragscore[notebook]" # + Jupyter/Colab support pip install "ragscore[all]" # + All providers
Already installed? Keep up to date — new versions add features like failure diagnosis and retrieved context capture:
`bash
pip install --upgrade ragscore
`
Perfect for Jupyter, Colab, and rapid iteration. Get instant visualizations.

Go beyond a single score. Add detailed=True to get 5 diagnostic dimensions per answer — in the same single LLM call.
result = quick_test(

display(result.df[[ "question", "score", "correctness", "completeness", "relevance", "conciseness", "faithfulness" ]])

| Metric | What it measures | Scale |
|---|---|---|
| Correctness | Semantic match to golden answer | 5 = fully correct |
| Completeness | Covers all key points | 5 = fully covered |
| Relevance | Addresses the question asked | 5 = perfectly on-topic |
| Conciseness | Focused, no filler | 5 = concise and precise |
| Faithfulness | No fabricated claims | 5 = fully faithful |
CLI:
ragscore evaluate http://localhost:8000/query --detailed
--diagnose)When answers fail, --diagnose tells you why — retriever miss, generator hallucination, incomplete answer, or wrong interpretation:
ragscore evaluate http://localhost:8000/query --diagnose
🔍 Failure Diagnosis:
Retriever Miss: 3 (42.9%) Generator Hallucination: 2 (28.6%) Incomplete Answer: 1 (14.3%) Wrong Interpretation: 1 (14.3%)
Uses the support_span already generated with each QA pair to give the judge grounding context. Combine with --detailed for full diagnostics:
ragscore evaluate http://localhost:8000/query --diagnose --detailed -o results.json
| Category | Meaning |
|---|---|
| Retriever Miss | RAG didn't retrieve the chunk containing the evidence |
| Generator Hallucination | Retrieved correctly but fabricated information |
| Incomplete Answer | Retrieved correctly but answer is partial |
| Wrong Interpretation | Retrieved correctly but misunderstood the content |

RAGScore generates complex structured QA pairs (question + answer + rationale + support span) in JSON format. This requires models with strong instruction-following and JSON output capabilities.
| Model | Size | Min RAM | QA Quality | Recommended |
|---|---|---|---|---|
llama3.1:70b | 40GB | 48GB VRAM | Excellent | GPU server (A100, L40) |
qwen2.5:32b | 18GB | 24GB VRAM | Excellent | GPU server (A10, L20) |
llama3.1:8b | 4.7GB | 8GB VRAM | Good | Best local choice |
qwen2.5:7b | 4.4GB | 8GB VRAM | Good | Good local alternative |
mistral:7b | 4.1GB | 8GB VRAM | Good | Good local alternative |
llama3.2:3b | 2.0GB | 4GB RAM | Fair | CPU-only / testing |
qwen2.5:1.5b | 1.0GB | 2GB RAM | Poor | Not recommended |
Minimum recommended: 8B+ models. Smaller models (1.5B–3B) produce lower quality support spans and may timeout on longer chunks.
# Recommended: 8B model with concurrency 2 for local machines
ollama pull llama3.1:8b ragscore generate docs/ --provider ollama --model llama3.1:8b
ollama pull qwen2.5:32b ragscore generate docs/ --provider ollama --model qwen2.5:32b --concurrency 5
Expected performance (28 chunks, 5 QA pairs per chunk):
| Hardware | Model | Time | Concurrency |
|---|---|---|---|
| MacBook (CPU) | llama3.2:3b | ~45 min | 2 |
| MacBook (CPU) | llama3.1:8b | ~25 min | 2 |
| A10 (24GB) | llama3.1:8b | ~3–5 min | 5 |
| L20/L40 (48GB) | qwen2.5:32b | ~3–5 min | 5 |
| OpenAI API | gpt-4o-mini | ~2 min | 10 |
RAGScore auto-reduces concurrency to 2 for local Ollama to avoid GPU/CPU contention.
