What’s On My Mind: A Large Language Model Power Technique
This week, Iβm going to share with you one power technique that will dramatically increase your productivity and accuracy when using large language models, like the ones that power ChatGPT and similar software. But before I delve into the technique itself, we need to go over some very basic foundational aspects of transformer-based models.
Large language models have two conceptual types of memory. This explanation is mathematically incorrect, so know that from the beginning, if you go read the relevant academic papers and you do the calculus yourself, this is not how the models mechanically work under the hood. But for now, this is a good conceptual model to remember.
Like you and me, language models have two kinds of memory, long-term and short-term. Long-term memory, also known by the fancy technical term latent space, is the statistical library of everything the model was trained on. To be clear, the original documents it was trained from are NOT in its long-term memory. Instead, a modelβs long-term memory is essentially a bunch of associations. Itβs seen βI pledge allegiance to theβ so many times that it can predict with near-mathematical certainty that the next word in the sentence should be flag, at least in North American English.
In general, the long-term memory of a language model is very large and diverse. Itβs seen everything from the most credentialed academic papers to your drunk uncleβs Reddit shitposts, and it has learned language patterns from it (this is why all models have biases). The process of building that long-term memory is so intensive and expensive that companies rarely do it. When they do, thereβs usually a big announcement, like when GPT-4, Claude 3, or Gemini 1.5 were announced, to much fanfare. This is why models often warn that they only have knowledge up to a certain date.
The short-term memory of a language model starts empty. Itβs the memory used during a conversation, so when you first open up a browser window to Gemini or Claude or ChatGPT, thereβs literally nothing there. The short-term memory is governed by some internal mechanics, but all models have a defined short-term memory; after you reach the limit of that memory, it starts forgetting the earliest parts of your conversation. How short is short-term memory? For some models, like the open-source LLaMa 2 model, the memory is as little as 2,200 words. For other models, like Claude 3 Opus and the upcoming Google Gemini 1.5, it’s as large as 700,000 words. Big or small, eventually models do run out of memory and delete the earliest information in their memories.
What makes transformers-based models – which is basically almost all language models today – different from their predecessors is a technical concept called attention. Without getting into details, the short conceptual summary is that attention means a model takes into account everything in its short-term memory to help predict what itβs going to say next. Everything in our prompt and subsequent conversations is used by the model for what it generates next.
I often call language models the smartest, most forgetful interns youβve ever worked with. Their knowledge in their long-term memories is substantial, more than any human could know. Their short-term memory means they have to constantly be reminded of what they know, even within the space of a single conversation.
So, with that somewhat technical background, letβs talk about this prompting power technique. It goes like this:
What do you know about this topic?
Kind of anti-climactic, isnβt it? Letβs see what it looks like in practice so we can see the value of it. Iβll start with the basic RACE framework prompt (grab the free, no form or data required PDF here):
You are an expert virologist and epidemiologist. You know viruses, viral replication, RNA, mRNA, protein structures, spike proteins, COVID-19, SARS-CoV-2, COVID variants, and immune escape. Your first task is to explain the importance of position 13,468 on Open Reading Frame 1ab of the SARS-CoV-2 virus and its significance for immunity.
That prompt fulfills the basic RACE framework. Letβs see what a model like ChatGPT says:
And for good measure, letβs see what Google Gemini says:
What’s important to note here is that both models have failed to mention the most salient fact about ORF1ab and position 13,468: it’s the mutation of the current COVID variant.
Now, letβs add our power technique:
You are an expert virologist and epidemiologist. You know viruses, viral replication, RNA, mRNA, protein structures, spike proteins, COVID-19, SARS-CoV-2, COVID variants, and immune escape. Your first task is to explain the importance of position 13,468 on Open Reading Frame 1ab of the SARS-CoV-2 virus and its significance for immunity. What do you know about this topic?
Let’s see what ChatGPT has to say:
and Gemini:
In both cases, the query that ends with asking it what it knows delivers more detailed results. That alone is helpful. However, more important is the continued omission of the basic fact that the JN.1 variant is why this mutation is so significant.
What does that tell us? Right out of the gate, it tells us that the long-term memory of these models does NOT have any information about the JN.1 variant, which in turn means that if we want to use generative AI for this topic, we will need to supply that information ourselves. This, by the way, is one of the reasons why subject matter expertise and human review still matter a great deal. To the untrained eye, these responses might look fine, but for anyone in virology, these are deeply deficient responses.
Second, if we were to proceed, then the short-term memory already has quite a bit more information in it. Remember that these transformers-based models take into account everything within the short-term memory, so by asking a model what it knows, we’ve effectively multiplied the length of the starting prompt by several times.
Let’s take something that requires a bit less current knowledge to further illustrate the point. Suppose you are a real estate agent and you want to write up a description of a property for sale. Let’s say these are the basics of the property:
- 2 bedrooms, 1 full bath
- House built in 1920
- House in terrible condition but livable
- 6 rooms total
- 4770 square foot lot
- $4,064 annual taxes
- Seller asking $440,000
- House has 1,122 square feet total with a shingle roof, block foundation, bungalow style
- House has city water and sewer
- Not in a particularly nice part of the city
- Houses selling fast in the city, only 10 single family homes available in the entire city of 70,000 people, very hot market
Now, if you were to use a language model with the RACE framework to prompt it to write a property description, it might go like this:
You are a top-selling real estate agent. You know real estate, realtors, house sales, single family homes, residential real estate, buyer’s agent, seller’s agent. Your first task, as the seller’s agent for a property, is to write a compelling description of this house to attract potential buyers. Here are the details: (paste in the list above) Write a compelling housing description.
What kind of description will we get?
Let’s see what ChatGPT has to say:
and Gemini:
These descriptions aren’t bad, but the models don’t have much to work with in the prompt, so what they come up with is a bit bland, generic, and dry.
Now, let’s start the conversation a little differently, using our power technique.
You are a top-selling real estate agent. You know real estate, realtors, house sales, single family homes, residential real estate, buyer’s agent, seller’s agent. Your first task, as the seller’s agent for a property, is to write a compelling description of this house to attract potential buyers. What do you know about the best practices for writing compelling real estate property descriptions to attract the attention of buyers?
Each model will tell us what it knows about the topic and some general best practices. What it’s doing as well is filling in what’s basically a very long prompt filled with the general best practices.
Let’s see what ChatGPT has to say:
and Gemini:
Now, with these pre-loaded expert prompts, let’s take a look at the revised listings.
Let’s see what ChatGPT has to say:
and Gemini:
Qualitatively, these responses are not just a little better, they’re a lot better. There’s still definitely some tweaking to do to make them better listings, but you can see just how including the basic best practices – pulled from the model’s long-term memory – into the conversation made for a better result.
Naturally, if your firm has a specific style of writing, or you have a database of listings that sold really fast, you’d want to include that context as well to create exactly the kind of output you want.
Asking a model what it knows about a topic is a fast way to tell whether or not the model is even capable of generating correct outputs, and pre-loading the conversation with rich information that substantially improves what it generates. Add this into your workflow to make your work with generative AI and large language models much better.
