Definition of Generative AI
Stated simply, generative artificial intelligence (GAI) is a system that relies on models trained on very large data sets to generate content (text, images, video) in response to a prompt.
This generated content is composed based on a model that is then tuned by companies and engineers, and that model predicts the likelihood of what output is most likely to associate with the words used in the prompt.
Generative AI is software�
In our conversations, we may use words like ‘learn,’ ‘understand,’ ‘teach,’ in our discussion of engagement with GAI tools.
Anthropomorphizing is a term that describes assigning human characteristics to GAI tools when they are just software.
Output can vary from one tool to another (and from one session to another)

Tokens and how Computers ‘Understand’ Language

How do computers make sense of natural language?
What should you take away from this explanation?
COMPUTERS CANNOT UNDERSTAND LANGUAGE THE WAY HUMANS DO.
ALL TEXT PRODUCTION IS A RESULT OF A PREDICTIVE PROCESS THAT IS *GUESSING* WHAT TOKEN COMES NEXT.
AI TOOLS DO NOT KNOW WHAT IS CORRECT OR INCORRECT. THEY DON’T KNOW THEIR OWN RELIABILITY.
ALL AI TOOLS RELY ON MODELS SHAPED BY THE DATASETS THAT INFORM THEM. THE MODELS ARE FURTHER TUNED BY COMPANIES AND ENGINEERS.
LLM-BASED TOOLS ARE NOT DESIGNED TO PROVIDE ANSWERS – THEY GENERATE BEST GUESSES ASSOCIATED WITH THE PROMPT
Kinds of Bias Possible in Output
• Availability bias
• Linguistic bias
• Cultural world views are conveyed in language
• Can result in incorrect translations
• Social bias
• More likely to generate stereotypical associations
• Low resourced information about underrepresented populations
• Bias in accounting of history or historical events
Errors and Confabulations – �Why might they happen
What GenAI can do reasonably well…
Generate multiple possible ways of organizing a set of words or ideas (or other quantitative aspects of texts)
Summarize or synthesize text from multiple sources for general content (not nuance)
Produce an average version of a common genre (like a travel itinerary or a sales pitch)
Smooth text to approximate an average use of American English or mimic well-defined styles
Write python code or provide syntax for R commands
Review an organizational document using well-defined criteria and with human oversight
Generate images that might help convey an idea or concept in a graphical rather than textual way (though they may reflect bias in their composition)
Visit websites and aggregate information with links into a table/csv file
What GenAI cannot do
Generative AI cannot produce text or images that:
Do generative AI tools boost efficiency?
Measuring productivity is complex:
Software engineering - tradeoffs from decreasing manual coding include more time spent debugging, increased code review, and cognitive overloading from constant output verification.
Professional Tasks – study of 3500 individuals found an increase in productivity by integrating genAI tools, but, reported 20% increased boredom and an increasing loss of motivation

Experience and domain knowledge may be key factors:
Faster but not always better – data analysts might use AI to quickly generate marketing copy, but without marketing expertise, work is of poor quality.
Expectations for efficiency gains vary – C-suite executives report much higher expectations for how much time genAI is saving employees than they are reporting
Tasks not well aligned for GenAI tools
GenAI is not the right tool to bring to tasks that depend on:

Agents
Put simply, an Agent is a software program that has the potential to act autonomously in some way. This can mean being given a high-level instruction without detailing the steps required to complete it or it can involve a complex series of tasks based on user input.
Agents are typically created using the following:
Agentic AI
Multi-agent systems rely on agent collaboration or competition to complete tasks. An example might be a system where one agent engages with a customer, another accesses a database and provides information, and another generates a return label or escalates the interaction to a human or some other personalized result.
Agentic AI is typically a multi-agent autonomous system acting according to predefined goals. It will collect information, formulate a strategy, undertake actions, and self correct (to an extent) to achieve its specific goal. The Canvas homework completion tool – Einstein for ex.

Is Resistance Futile?
In work, productivity gains may be more likely to happen when well-aligned systems are implemented in ways that augment, rather than replace, human activity.
Responsible Use
Data Privacy
Transparency and Disclosure
Consider Local Norms
Review Authorship Policies
Avoid Plagiarism
Remember Bias
