What’s On My Mind: How To Evaluate a Generative AI System
I strongly encourage you to watch the video edition of this week’s newsletter to see the actual results of generative AI.
This week, Google rebranded and relaunched its Bard service as Gemini, while OpenAI was making noises about GPT-5. Stable Diffusion’s Stable Video got a nice buff in terms of video quality output, and Mistral Medium has been climbing the charts over at LMSys’ Chatbot Arena. With all these models, it might be tempting to throw your hands up, pick one with a throw of a dart, and call it a day. So today, let’s talk about HOW to evaluate models to decide which is best for you.
Unsurprisingly, we’ll be using the Trust Insights 5P Framework to do this evaluation. Here are the five parts:
- Purpose: what task do you want the model to do?
- People: who will be using the model?
- Process: what prompt will you be evaluating the model with?
- Platform: which models are you evaluating?
- Performance: score the models based on their output.
This is a very straightforward testing framework, but it helps codify and simplify the testing process – especially when you have a lot to test, or you have specific needs for testing.
So let’s dig in.
Purpose
What task do you want the model to perform? Ideally this is a task suited to the model type you’re working with. For example, suppose you want to render an image as digital art. You have a gigantic bounty of open weights models on sites like Hugging Face and CivitAI as well as commercial SaaS tools like DALL-E, Microsoft Bing Image Creator, Photoshop, and Google Gemini.
The first step is to clearly define the task. What do you want to do? What are the criteria for success? For example, if you’re rendering an image of, say, a middle-age Korean woman CEO, at the very least the image should look like that kind of person – correct number of fingers, not blatantly a racist caricature, etc. If you’re evaluating a model to pick the winner of the Super Bowl, you’d want a clear, definitive answer, probably along with some reasoning about the model’s choices.
People
If you’re evaluating models for work, who else besides you will be using the model? What skills does that person need? Will they need to revise and upgrade your prompt? Understanding who the people are that will benefit from your selected model is critical – a model, for example, that requires relatively technical setup is probably going to be a non-starter for non-technical people. A good example of this is setting up ComfyUI with Stable Diffusion. For a technically skilled person, setting up this environment is trivial. For a non-technical person, asking them to clone a Git repo and run local Python code may as well be asking them to interpret ancient Sumerian.
We have to know our people to know what processes and platforms are even on the table.
Process
For model comparison, we want a standardized prompt that follows basic best practices and is relatively portable across systems. After all, if there’s an important task you want to accomplish with a generative AI model, you want that task to work well on your platform of choice. Thus, you want to invest a lot of time up front in thinking through what that prompt should look like.
For example, with my Super Bowl prediction prompt, I copied all the post-season data from the NFL public website for offense, defense, and special teams for the two teams playing, plus set up a tree-of-thought prompt to walk through the data and really invest time in digging through it.
Generally speaking, big public models like Gemini, GPT-4, and Claude 2.1 can all more or less interchangeably parse the same prompt in very similar ways. They have enough data in them that you probably won’t get wildly different results. Some systems, like Bing and Gemini, will also augment what the models knows with data from other platforms, so clarifying whether a task relies on external data is important. Again, with my Super Bowl prompt, Bing and Gemini both pulled in player data as well as the team data I supplied, giving more robust answers than ChatGPT did.
Platform
Choosing a model depends on the task you’re trying to accomplish. If you’re doing language tasks, choose a language model and system like ChatGPT. If you’re doing image tasks, choose an image or multimodal model like DALL-E or Stable Diffusion. If you’re not sure, start with a multimodal model – Gemini and paid ChatGPT are good places to start.
How do you know what kind of model to pick? It’s based on your Purpose, which is why we start with purpose. Clearly defining what we want makes it easier to evaluate a model.
Performance
Finally, we get to the evaluation itself. Generally speaking, you want a combination of qualitative and quantitative evaluation. For tasks with clear success parameters – like extracting data from text into a table, for example – you want to have numeric scores. I use a 3 point system – 0 points if a model fails, 1 point if it minimally succeeds but quality of response is low, and 2 points if it fully succeeds. Again, for something like tabular data, if a model produces word salad and not a table, that would be a 0. If it makes a table but the table is clearly wrong, that’s a 1. And if it succeeds in processing the data correctly, that’s a 2.
So let’s step through an example to see how this might play out. I was talking with my friend Ashley Zeckman, CEO of Onalytica, the other day about thought leadership in the context of publishing content on LinkedIn. In that discussion, we realized that there were some very divergent points of view about what thought leadership even was. So let’s make a tree of thought prompt about the topic to see if we can arrive at a fresh, original perspective.
First, the purpose is clear. I’ll use a user story to define it. As a content creator, I need to determine which language model is capable of generating the most unique insights on a topic using tree of thought prompting so that I can have generative AI create better, more original content.
That’s a pretty clear user story. The people – well, that’s me. Let’s take a look at the process.
Here’s the prompt I’ll use:
Today, we’re going to simulate an academic debate between two points of view, along with a debate moderator. The topic of the debate is thought leadership in the context of marketing, personal brand, and social media. Our two debate contestants are:
– Ashley Awesome: Ashley Awesome is a personal branding expert who coaches executives on thought leadership and building a personal brand, especially on platforms like LinkedIn, YouTube, and Medium. Ashley wholeheartedly believes in the power of personal branding and thought leadership, and thinks thought leadership should be a core strategic pillar of any executive and company. Ashley’s tone is typically optimistic, but she can become frustrated when dealing with someone displaying willful ignorance or condescension.
– Christopher Contrary: Christopher Contrary is a marketing expert who is a non-believer in personal branding and thought leadership. Christopher thinks thought leadership is thinly disguised narcissism and promotional sales content, and so-called “thought leaders” on many platforms are recycling obvious points of view or taking needlessly provocative stances on settled issues to generate vapid attention. Christopher’s tone is confrontational and contrary, and can become brusque when repeatedly challenged.
The debate will be moderated by Betty Balanced. Betty is a cool-headed moderator with extensive experience in moderating controversial topics in high-stakes debates like presidential forums.
Structure the debate as a question from the moderator, followed by responses from each contestant. Each contestant may reply once in rebuttal before Betty moves onto the next debate question.
This is the format the debate should take:
“””
BETTY: Good afternoon, ladies and gentlemen. Welcome to the World Leadership Forum. I’m your moderator, Betty Balanced. Today we will be hearing from our contestants, Ashley Awesome and Christopher Contrary, on the topic of thought leadership. Welcome, Ashley and Christopher.
ASHLEY: It’s a pleasure to be here.
CHRISTOPHER: Thank you for having me.
BETTY: With introductions out of the way, let’s begin with our first debate point. What is, from your point of view, thought leadership?
“””
After a question has been answered and rebutted, wait for feedback from me, the user.
Begin the debate by having Betty ask the contestants to each define thought leadership.
In terms of platform, I want to evaluate Claude 2.1 in the Anthropic interface, GPT-4-Turbo in the OpenAI Playground, and Gemini in the Google Gemini interface.
Watch the video for this issue of the newsletter to see how GPT-4-Turbo, Claude 2.1, and Gemini handle this complex prompt.
You’d follow this process for any generative AI system. If you wanted to evaluate an image, you’d follow the 5Ps to set your purpose, determine the people involved, build a complex, robust prompt, choose the models and systems you want, and then evaluate the results. The reason you should do this is so that you evaluate generative AI for your specific needs. There are a lot of benchmarks and comparisons that people publish about all these different models, but most of the time, those benchmarks don’t reflect your specific needs. By following this framework, you will find the best fit for the generative AI model that meets your specific use cases – and it may not be the same model and software that others say is the best. Best is often personal.
