Life as an ML Engineer: When the LLM Is More Confident Than You! 😂
Me: “Answer only using the provided documents.”
LLM: “Absolutely! I will be accurate and grounded.”
The LLM 2 seconds later: Invents a company, three statistics, and a research paper that has never existed.
Me: “Where did you get this information?”
LLM: “Trust me, bro.” 🤝😂
And then begins the real engineering work:
Checking retrieval quality
Adjusting chunk sizes
Improving prompts
Evaluating hallucinations
Checking token costs
Trying to reduce latency
After hours of debugging…
Me: “Let's try adding a reranker.”
LLM: Still confidently wrong, but now slightly slower and more expensive. 😭
Building a GenAI demo is fun. Making it reliable enough for production? That's the real adventure.
AI engineers, be honest: What's your biggest LLM headache?
1️⃣ Hallucinations
2️⃣ Bad retrieval
3️⃣ Latency
4️⃣ The cloud bill after deployment 😂
