Overview: Large language models

While this overview will eventually reflect everything tagged #llm on this Hub, my current focus is on how LLMs could best support MyHub users in particular and inhabitants of decentralised collective intelligence ecosystems in general (cf. How Artificial Intelligence will finance Collective Intelligence). This is version 1.x, 2023-04-24.

How the hell does this work?

The best explanation of how it works by far comes from Jon Stokes' ChatGPT Explained: A Normie's Guide To How It Works. In essence, "each possible blob of text the model could generate ... is a single point in a probability distribution". So when you Submit a question, you're collapsing the wave function and landing on a point in that probability distribution: a collection of symbols probably related to what you inputted. That collection's content depends "on the shape of the probability distributions ... and on the dice that the ... computer’s random number generator is rolling."

So if you ask whether Schrodinger's Cat is alive or dead, you'll get different answers depending on how you ask the question not because the LLM understands anything about Schrodinger, his cat or quantum mechanics, but because amongst all "possible collections of symbols the model could produce... there are regions in the model’s probability distributions that contain collections of symbols we humans interpret to mean that the cat is alive. And ... adjacent regions ... containing collections of symbols we interpret to mean the cat is dead. ChatGPT’s latent space has been deliberately sculpted into a particular shape by...":

  • Training "a foundation model on high-quality data" so it's "like an atom where the orbitals are shaped in a way we find to be useful.
  • Fine-tuning "it with more focused, carefully curated training data" to reshape problematic results
  • Reinforcement learning with human feedback (RLHF) to further refine the "model’s probability space so that it covers as tightly as possible only the points ... that correspond to “true facts” (whatever those are!)"

The key takeaway here is that ChatGPT is not truly talking to you, it's "just shouting language-like symbol collections into the void". And here's a good example of its spectacularly wrong hallucinations.

What the hell does it mean?

As such it is not "almost AI", it's not even close. According to Noam Chomsky, "The human mind is not... a lumbering statistical engine for pattern matching... True intelligence is demonstrated in the ability to think and express improbable but insightful things.... [and is] also capable of moral thinking", whereas ChatGPT's "moral indifference born of unintelligence... exhibits something like the banality of evil: plagiarism and apathy and obviation", summarising arguments but refusing to take a position because its creators learnt their lesson with Taybot.

Not understanding this is dangerous, as the interview/profile of Emily M. Bender in You Are Not a Parrot And a chatbot is not a human makes clear: "LLMs are great at mimicry and bad at facts... the Platonic ideal of the bullshitter... don’t care whether something is true or false... only about rhetorical power. [So] do not conflate word form and meaning. Mind your own credulity... [we've made] machines that can mindlessly generate text... we haven’t learned how to stop imagining the mind behind it."

Believing an LLM understands what it says is particularly a problem given that it was trained on words written overwhelmingly by white people, with men and wealth overrepresented (see also OpenAI’s ChatGPT Bot Recreates Racial Profiling). Bender is very good on what the safe use of artificial intelligence looks like (TL:DR; ChatGPT ain't it), covering the dehumanising effect of treating LLMs like humans, and humans like LLMs, and asking what happens when we habituate "people to treat things that seem like people as if they’re not”? Won't we all start treating real humans worse?

Answer: we might "lose a firm boundary around the idea that humans... are equally worthy", bordering on fascism: "The AI dream is governed by the perfectibility thesis... a fascist form of the human."

For more on why we must avoid a tiny number of companies dominating the field:

How can I use it?

Understanding how it does what it does is key to understanding the answer to this question, so Stokes' Normie's Guide, above, is also good here: "Isn’t the model’s ability to make things up often a feature, not a bug?".

More practically:

  • in The Mechanical Professor Ethan Mollick, uni professor, puts ChatGPT through its paces. From my notes: impressive as a teacher, not great as a researcher/academic writer ("Nothing particularly wrong, but also nothing good"), reasonable summariser and general writer ("results were not brilliant, and I wouldn’t vouch for their accuracy"). So while not yet a threat to real academics, ChatGPT is a jobkiller for copywriters, almost everyone on New Grub Street and anyone else spending their days churning out rehashed content.
  • learn something: give it a summary of something (or ask it so summarise, but then doublecheck for hallucinations), and then ask it to ask you questions about it and rate your answers. But doublecheck for hallucinations...

Prompt engineering

My reading queue is overflowing with identikit posts on prompt engineering, which I'll get to eventually.

AutoGPT: adding value to LLMs to create focused AI assistants

"AutoGPTs... automate multi-step projects that would otherwise require back-and-forth interactions with GPT-4... enable the chaining of thoughts to accomplish a specified objective and do so autonomously" - something I've already played with inthe shapre of AgentGTP, and which encapsulates how I'll integrate this into MyHub.ai (next), because this approach "transforms chat from a basic communication tool into ... AI into assistants working for you".

How should it be integrated into MyHub?

How could these LLMs be integrated into tools for thought in general, and (tomorrow's) MyHub.ai in particular? I've always wanted to access AI services from inside the MyHub thinking tool (see Thinking and writing in a decentralised collective intelligence ecosystem), from where it can apply its abilities to one's own notes. But what will that look like?

My first thought: "imagine your own personal AI assistant operating across your content - your public posts, private library (including content shared from friends, stuff in your reading queue, etc.) and the wider web, emphasising the sources you favour (based firstly on your Priority Sources, and then on the number of times you've curated their content)."

In I Built an AI Chatbot Based On My Favorite Podcast, the author shows how to do just that: "It took probably a weekend of effort" to build a chatbot to search his library "of all transcripts from the Huberman Lab podcasts, finds relevant sections and send them to GPT-3 with a carefully designed prompt".

A step-by-step guide to building a chatbot based on your own documents with GPT goes into far more detail.

Pretty soon I'll be able to do something similar, playing with ChatGPT combined with my entire Hub of over 3600 pieces of content. But while the above chatbot answers questions, I'm already pretty sure I don't want to treat ChatGPT like a search engine.

Instead, going into this experiment, ChatGPT as muse, not oracle is my overall starting point, asking "What if we were to think of LLMs not as tools for answering questions, but as tools for asking us questions and inspiring our creativity? ... ChatGPT asked me probing questions, suggested specific challenges, drew connections to related work, and inspired me to think about new corners of the problem."

Other ideas include:

  • as a tutor, as in The Mechanical Professor, who "put the text of my book into ChatGPT and asked for a summary ... asked it for improvements... to write a new chapter that answered this criticism... results were not brilliant, and I wouldn’t vouch for their accuracy, but it could serve a basis for writing."
  • finding me content on the web based on my interests, as represented by my notes
  • auto-categorisation: I've been manually tagging stuff I like since 2002. I have not been consistent in the use of tags. Can ChatGPT help me organise my stuff?

Or should it be integrated at all?

But I'm mindful that I might not find it that useful. Many years ago, for example, I thought I wanted autosummary: click a button and get an autosummary of an article in my Hub. But that risks robbing me of any chance of learning anything from it.

Moreover, as Ted Chiang points out in ChatGPT Is a Blurry JPEG of the Web, AI should not be used as a writing tool if you're trying to write something original: "Sometimes it’s only in the process of writing that you discover your original ideas... Your first draft isn’t an unoriginal idea expressed clearly; it’s an original idea expressed poorly", accompanied by your dissatisfaction with it, which drives you to improve it. "just how much use is a blurry jpeg when you still have the original?"

Which links to a piece not tagged "llm", where Jeffrey Webber points to a central problem with Tools for Thought: "the word ‘Tool’ first causes us to focus on the tool more than the thinking... to confuse thought as an object rather than thought as a process... obsessed with managing notes, the external indicator of thought, rather than the internal process of thinking... we do less and less of the thinking and more and more of the managing."

Can AI help? Maybe, but would we be as willing to have another human do our thinking?
