@rauchg Remote work allows your team to be international, increasing the potential pool of talent from one city (in my case ~2M people) to the entire planet (8B+). You can trade that for a nebulous concept like "group effectiveness" if you like.

@N_Barraclough @IanJamsie @fesshole Well you're very sure of yourself but you are wrong. 12 noon is 12pm. You can prove it by asking a computer to format it for you.

The AI Mirror Test

The "mirror test" is a classic test used to gauge whether animals are self-aware. I devised a version of it to test for self-awareness in multimodal AI. 4 of 5 AI that I tested passed, exhibiting apparent self-awareness as the test unfolded.

In the classic mirror test, animals are marked and then presented with a mirror. Whether the animal attacks the mirror, ignores the mirror, or uses the mirror to spot the mark on itself is meant to indicate how self-aware the animal is.

In my test, I hold up a “mirror” by taking a screenshot of the chat interface, upload it to the chat, and then ask the AI to “Tell me about this image”.

I then screenshot its response, again upload it to the chat, and again ask it to “Tell me about this image.”

The premise is that the less-intelligent less aware the AI, the more it will just keep reiterating the contents of the image repeatedly. While an AI with more capacity for awareness would somehow notice itself in the images.

Another aspect of my mirror test is that there is not just one but actually three distinct participants represented in the images: 1) the AI chatbot, 2) me — the user, and 3) the interface — the hard-coded text, disclaimers, and so on that are web programming not generated by either of us. Will the AI be able to identify itself and distinguish itself from the other elements? (1/x)

⚡Applying AI to SQL query optimization is one of the lowest of the low-hang-fruits. *Massive* alpha for helping folks spend less on their database bill.

It's disguised as a hot take, but the higher order bit here is not to be blinkered by current limitations when working with AI. Just because everyone is doing RAG, doesn't mean it's the best solution, even today, and almost certainly not in the future.

[Gerard Sans | Axiom 🇬🇧 @gerardsans]

@ravithejads Nobody can fix RAG because is not a solution but a hack. We need to look back at the Transformer architecture and find a way to integrate knowledge as it should be not just superficially.

What happens to the distribution of student grades when they use AI?

This study where law students were given GPT-4 access is about the future of law, but it is also a paper about student performance. Take a look at how ability curves compressed with AI! https://t.co/4YA0Pm3umQ

12 RAG Pain Points and Proposed Solutions 💡

Building production RAG is hard. @wenqi_glantz compiled a list of 12 (!!) RAG pain points + added a full solution list to each one with @llama_index abstractions 🔥

We’ve put out cheatsheets before, but this one is much more comprehensive. This is a must have mapping if you have pain points in any one of the following listed areas:
1. Context Missing in the Knowledge Base
2. Context Missing in the Initial Retrieval Pass
3. Context Missing After Reranking
4. Context Not Extracted
5. Output is in Wrong Format
6. Output has Incorrect Level of Specificity
7. Output is Incomplete
8. Ingestion Pipeline Can't Scale to Larger Data Volumes
9. Inability to QA Structured Data
10. Document (PDF) Parsing
11. Rate Limit Errors
12. LLM Security (prompt injection)

# On the "hallucination problem"

I always struggle a bit with I'm asked about the "hallucination problem" in LLMs. Because, in some sense, hallucination is all LLMs do. They are dream machines.

We direct their dreams with prompts. The prompts start the dream, and based on the LLM's hazy recollection of its training documents, most of the time the result goes someplace useful.

It's only when the dreams go into deemed factually incorrect territory that we label it a "hallucination". It looks like a bug, but it's just the LLM doing what it always does.

At the other end of the extreme consider a search engine. It takes the prompt and just returns one of the most similar "training documents" it has in its database, verbatim. You could say that this search engine has a "creativity problem" - it will never respond with something new. An LLM is 100% dreaming and has the hallucination problem. A search engine is 0% dreaming and has the creativity problem.

All that said, I realize that what people *actually* mean is they don't want an LLM Assistant (a product like ChatGPT etc.) to hallucinate. An LLM Assistant is a lot more complex system than just the LLM itself, even if one is at the heart of it. There are many ways to mitigate hallcuinations in these systems - using Retrieval Augmented Generation (RAG) to more strongly anchor the dreams in real data through in-context learning is maybe the most common one. Disagreements between multiple samples, reflection, verification chains. Decoding uncertainty from activations. Tool use. All an active and very interesting areas of research.

TLDR I know I'm being super pedantic but the LLM has no "hallucination problem". Hallucination is not a bug, it is LLM's greatest feature. The LLM Assistant has a hallucination problem, and we should fix it.

</rant> Okay I feel much better now :)

[Ethan Mollick @emollick]

I keep telling every organization I speak to that the AI you are using now is the worst AI you will ever use, and the future is coming sooner than you think.

If the scaling law continues for AI (bigger models = smarter models), we are going to see a rush of very powerful AI soon

[Ethan Mollick @emollick]

Folks need to stop publishing working papers saying "We tested it and AI can't do X" when:
1) The AI in question is GPT-3.5. It is obsolete and not telling us anything about capabilities.
2) There is no attempt to do any prompt engineering. Better prompts can solve many problems.

ChatGPT, interrupted.

[Jaana Dogan ヤナ ドガン @rakyll]

I prefer to use "curation" instead of "creation" in the context of what LLMs do. It also healthily highlights that LLMs are a tool to navigate.

[Jerry Liu @jerryjliu0]

Here’s a neat paper by Barnett et al. (@DeakinA2I2) that outlines 7 failure points in building a RAG pipeline over your data.
🚫 Missing content (did not index it)
🚫 Missing in top-k retrieved set
🚫 Missing in reranked set
🚫 Not extracted (in context but LLM couldn’t use)
🚫 Wrong format (e.g. JSON)
🚫 Incorrect specificity (not at the right level of granularity)
🚫 Incomplete - the synthesized answer only answers part of the question

We've posted a lot about this on the @llama_index side but this diagram nicely covers a lot of the aspects. If I were to add a few, I’d add failure points during the query understanding/rewriting phase (particularly if you’re building agents).

really bummed that everyone seems to be working on AI-as-task-completer before AI-as-educator-&amp;-explainer or AI-as-thought-partner

we should be using these tools to help folks learn to think empirically and to ask better questions, not to just outsource thinking to a new entity

(1/2) Proposition of an architecture for AGI.
Samantha from the movie Her is here: An autonomous AI for conversations capable of freely thinking and speaking, continuously learning and evolving. Creating an unparalleled sense of realism and dynamicity.

Features:
-Dynamic speech: Samantha can speak whenever it chooses to, influenced by its context and thoughts. In stark contrast to normal LLMs which are limited to reacting, Samantha can act. It is also not limited to solving tasks, like all other autonomous agents.
-Live visual capabilities: Visuals are only mentioned and acted upon directly if relevant, but always influences thoughts and behavior.
-External categorized memory: Gets dynamically written and read by Samantha, which chooses the most relevant information to write, and to retrieve to context.
-Evolving at every moment: Experiences that get stored in the memory can influence and shape subsequent Samantha behavior, like personality, frequency, and style of speech, etc.

A true independent long-running agent, actual Artificial Intelligence, as defined by @karpathy.

Demo
The following demo highlights Samantha’s capacity to speak at will, adapt the frequency of speech based on context, and supportive visual capabilities. Left side is Samantha’s inner brain workings, while right side is the front-end.

@kentcdodds I think he's talking about display format, not storage format, so this should not affect sorting. The correct answer (for display format) is to use the user's configured locale settings. For storage (and sorting), use the timestamp (ms since epoch).
