Eva noticed Mo's puzzled expression and decided to address a common curiosity. "Mo, I see you're wondering why sometimes ChatGPT, like Charger, gives unexpected answers. Let's unravel this mystery."

"First, let's talk about 'hallucinations' in the world of AI," Eva started. "Imagine if our village storyteller, instead of sticking to known tales, started weaving stories with dragons and fairies based on a few words he heard. That's similar to what happens with LLMs like Charger. They sometimes 'hallucinate' or give answers based on partial understanding or patterns they've learned, rather than solid facts."

Why Hallucinations Occur

"Think of it as our storyteller getting carried away without the complete picture," Eva explained. "Hallucinations in LLMs often occur when they don't fully grasp the context of a prompt. Sometimes, it's because the training data they learned from was incomplete or not entirely accurate. These AI models, like our storyteller, rely on the stories – or data – they've been told, not on real-time, real-world information."

"But fear not," Eva reassured, "there are ways to keep our digital storyteller on track, like using Retrieval Augmented Generation. It's like giving our storyteller a library of current books to reference, ensuring the stories stay relevant and factual. Products like Google Bard, Perplexity or Bing provide references or citation along with the response to avoid the hallucination or cross reference the original sources."

Reducing Hallucinations: Techniques

"Now, let's dive into how we can reduce these hallucinations," Eva continued. "Sometimes, a little imagination is good, like when creating a fictional story or a catchy marketing slogan. But when we need Charger to stick to the facts, we use several techniques."

  1. Prompt Engineering: "By adding more details to our prompts, we give Charger clearer directions. It's like providing our storyteller with a detailed script to follow, ensuring the story stays on course."
  2. In-Context Learning: "Giving Charger more context is like giving our storyteller background information about his audience. It helps Charger understand better what's expected and tailors its responses accordingly."
  3. Controlled Generation: "We also set boundaries in our prompts. It's like telling our storyteller the specific themes to stick to, preventing him from veering off into fantasy land."

Eva concluded, "While we can't completely eliminate hallucinations, these methods help keep Charger's responses more accurate and relevant."

The villagers, now enlightened about the nature of AI's 'hallucinations,' chuckled at the analogy. Mo, particularly, seemed satisfied with the explanation, his curiosity quenched. The gathering buzzed with discussions, the villagers now more intrigued than ever by the capabilities and quirks of their AI creation.


Eva, with a spark in her eyes, geared up to address a question buzzing among the villagers. Dr. Ingrid and other villagers, curious about the practicality of LLMs, listened intently.

Bringing LLMs Home with MLC

“Have you ever wished you could have a mini version of Charger right on your laptop?” Eva asked the crowd. “Well, with Machine Learning Compilation, or MLC, that's not just a Christmas wish anymore!”

A villager piped up, “But Eva, isn’t running an AI model like Charger a complex task?”

Eva nodded. “Absolutely, but think of MLC as a Christmas elf who’s excellent at packing big gifts into small boxes. It packs the power of LLMs into our local devices, making them run faster and efficiently. Whether you have a PC, Mac, or even a tablet, MLC is like Santa’s helper, making sure everyone gets to enjoy the magic of AI!”

llama.cpp: LLMs on MacBooks

“Now, for the MacBook users among us,” Eva continued, “there's something special called llama.cpp which is a port of facebook's LLaMA in C/C++ to run on MacBook. It’s like having a compact Christmas gadget that can light up the biggest tree with ease.”

A young student, Lily, raised her hand. “Does that mean I can run Charger on my MacBook for my school projects?”

“Yes, Lily!” Eva replied. “llama.cpp uses tech wizardry to make Charger run smoothly on your MacBook. It's like having a smart cookie cutter that shapes dough into any Christmas cookie design you want – efficient and precise!”

Eva then turned to her laptop for a live demonstration. “Let’s ask Charger for a fun Christmas recipe, shall we?”

As Charger churned out a delightful recipe for gingerbread cookies, the crowd gasped in amazement.

“Imagine the possibilities,” Eva said, closing her laptop. “Recipes, homework help, business insights – all powered by AI on your own devices!”

The villagers buzzed with excitement, their minds whirling with ideas. Dr. Ingrid, her curiosity piqued, wondered aloud, “Could this technology help me in my linguistic research?”

Eva nodded enthusiastically. “Absolutely, Dr. Ingrid! The potential is limitless.”
