I read all 154 pages of Microsoft Research's "Sparks of AGI".
Most people don't realise the shocking reality AI is going to bring.
Here's what I found:
1/ Tool use
GPT-4 suffers from serious limitations:
β€’ Lack of world knowledge after September 2021
β€’ Difficulty with math
β€’ Can't execute code
However GPT-4 can use external tools like search engines, APIs and plugins to overcome these limits.
For humans, the use of tools was a milestone in history.
It allowed us to overcome the limitations of our physical abilities.
The same can be said for GPT-4.
It can use tools with:
β€’ No demonstration
β€’ Minimal instruction
β€’ Make appropriate use of the output
2/ AI personal assistant
GPT-4 can use multiple tools at once:
β€’ Retrieves information about a user’s calendar
β€’ Coordinates with others over email
β€’ Books a dinner reservation
β€’ Messages details to the user
It can reason with free-form output to solve complex problems.
3/ Mental maps
GPT-4 is asked to explore a house and build a mental map.
It then summarises what it sees after navigating through the map.
4/ Virtual handyman
GPT-4 is able to identify the actions a human needs to take in order to address a problem.
β€’ Guides the human to find and fix a water leak
β€’ Recommends the exact actions for the human to take
The human acts as GPT-4's real-world agent.
5/ Challenges and limitations
GPT-4 is a next-word prediction model.
It predicts future values based on past values.
It lacks:
β€’ Planning
β€’ Working memory
β€’ Reasoning abilities
Whilst it can produce coherent text generation it struggles with complex problems.
This can be broken into two types of intellectual tasks.
Incremental tasks (GPT-4 is great at these)
β€’ Solved sequentially or gradually
β€’ Progress made by adding one word or sentence at a time
β€’ Examples: writing summaries, answering factual questions, composing poems
Discontinuous tasks (GPT-4 is bad at these)
β€’ Require a creative leap in progress
β€’ Involves discovering new ways to frame problems
β€’ Examples: writing jokes, developing scientific hypotheses or new writing styles
What I'm excited for:
β€’ Augmenting GPT-4 and language models with external memory
β€’ Implementing feedback loops
β€’ Equipping language models with plans
With the recent addition of plugins to GPT-4 we have some exciting times ahead.
I feel the fire has been lit as we approach AGI.
