Your AI just confidently told a customer that pandas eat metal, that Paris is in Germany, or that a completely fictional API endpoint exists.
You've been there. We all have.
Your model is brilliant 99% of the time, but that 1% of hallucinations? It's destroying user trust, costing you customers, and keeping you awake at night wondering when the next embarrassing AI mistake will hit production.
Traditional solutions are bandaids:
- ❌Fine-tuning takes months and costs thousands
- ❌Prompt engineering is fragile and breaks with edge cases
- ❌Guardrails only catch problems after they happen
- ❌RAG systems are slow and often retrieve irrelevant context
What if your AI could fact-check itself before speaking?
memories-dev gives your AI acontextual memory system that verifies responses against real-world data in real-time. Think of it as a fact-checking copilot that sits between your model and your users.
1. Your AI generates a response2. memories-dev instantly checks it against verified data sources3. Only truthful, contextually-accurate responses reach your users4. Hallucinations are caught and corrected automaticallyResult: Your AI becomes reliable enough for mission-critical applications.
Go from installation to stopping hallucinations in under 5 minutes:
pip install memories-dev
frommemoriesimportSimpleMemoryStorefromopenaiimportOpenAI# Optional - works with any AI# Initialize memory system (works without any dependencies!)memory_store=SimpleMemoryStore()# Store geographical facts in hot memorymemory_store.store("geography_facts", {"france_capital":"Paris","spain_capital":"Madrid","italy_capital":"Rome"},tier="hot")# Your AI call (example with OpenAI, but works with any AI)# client = OpenAI()# response = client.chat.completions.create(...)# Simulate AI response for demoai_response="The capital of France is Paris"# Cross-check with memorystored_facts=memory_store.retrieve("geography_facts")print(f"AI said:{ai_response}")print(f"Memory confirms: France's capital is{stored_facts['france_capital']}")print(f"✅ Response verified against stored facts!")
# Test advanced hallucination detectionhallucinated_claim="The capital of France is Lyon"# Wrong! ❌# Use built-in hallucination detectionresult=memory_store.detect_hallucination(hallucinated_claim, ["geography_facts"])print(f"Claim:{result['claim']}")print(f"Verified:{result['is_verified']}")print(f"Confidence:{result['confidence']:.1%}")ifnotresult['is_verified']:print("❌ Hallucination detected!")correct_facts=memory_store.retrieve("geography_facts")print(f"✅ Correct answer:{correct_facts['france_capital']}")# Test with correct informationcorrect_result=memory_store.detect_hallucination("The capital of France is Paris", ["geography_facts"] )print(f"\n✅ Correct claim verified:{correct_result['is_verified']}")
Congratulations! You just eliminated a whole class of AI errors. Your users will never see that hallucination.
🔰 I'm New to AI Safety - Start here if you're exploring AI reliability solutions
AI hallucinations aren't just embarrassing—they're expensive:
- Customer trust: 73% of users lose confidence after one AI mistake
- Business impact: Companies lose $62M annually to AI errors
- Developer time: Teams spend 40% of their time debugging AI outputs
Unlike other solutions, we don't just detect problems—weprevent them:
| Traditional Approach | memories-dev |
|---|---|
| 🔍 Detect hallucinations after they happen | ✨ Prevent hallucinations before they reach users |
| 🐌 Slow fact-checking (5-10 seconds) | ⚡ Real-time verification (<100ms) |
| 🔧 Complex setup requiring ML expertise | 🎯 Simple API that works with any AI model |
| 💸 Expensive fine-tuning and retraining | 📈 Zero-training solution that improves over time |
"We reduced AI hallucinations by 94% in our customer service bot. Support ticket volume dropped 60%."
— Sarah Chen, CTO at TechFlow
"memories-dev saved us from a potential PR disaster. Our AI was about to give medical advice that could have been dangerous."
— Dr. Michael Rodriguez, Healthcare AI Startup
