What we can reasonably assume from statements made by insiders: They want a 10x improvement from scaling and a 10x improvement from data and algorithmic changes The sources of public data are essentially tapped Algorithmic changes will be an unknown to us until they release, but from published research this remains a steady source of improvement Scaling seems to stall if data is limited So with all of that taken toge…

Great improvements and all, but they are still no closer (as of 4o regular) to having a system that can be responsible for work. In math problems, it forgets which variable represents what, in coding questions it invents library fns. I was watching a YouTube interview with a "trading floor insider". They said they were really being paid for holding risk. The bank has a position in a market, and it's their ass on the…

> ChatGPT (as far as I can tell) is no closer to being accountable or responsible for anything it produces.

What does it even mean? How do you imagine that? You want OpenAI to take on liability for the kicks of it?

"OpenAI’s is called GPT-4, the fourth LLM the company has developed since its 2015 founding." - that sentence doesn't fill me with confidence in the quality of the rest of the article, sadly.

There’s nothing grammatically offensive about this. It’s like saying, “Cars come in all colors. Mine is red.”

"Orion’s problems signaled to some at OpenAI that the more-is-more strategy, which had driven much of its earlier success, was running out of steam." So LLMs finally hit the wall. For a long time, more data, bigger models, and more compute to drive them worked. But that's apparently not enough any more. Now someone has to have a new idea. There's plenty of money available if someone has one. The current level of LLM…

What wall? Not a week has gone by in recent years without an LLM breaking new benchmarks. There is little evidence to suggest it will all come to a halt in 2025.

Sure, but "benchmarks" here seems roughly as useful as "benchmarks" for GPUs or CPUs, which don't much translate to what the makers of GPT need, which is 'money making use cases.'

We are close. Language models and large vision models have transformed robotics. It just takes some time to get hardware up and running.

I think it would be many decades before I'd trust a robot like that around small children or pets. Robots with that kind of movement capability, as well as the ability it pick up and move things around, will be heavy enough that a small mistake could easily kill a small child or pet.

That's a solved problem for small devices. And we effectively have "robots" like that all over the place. Sliding doors in shops/trains/elevators have been around for ages and they include sensors for resistance. Unless there's 1. extreme cost cutting, or 2. bug in the hardware, devices like that wouldn't kill children these days.

O3 has demonstrated that OpenAI needs 1,000,000% more inference time compute to score 50% higher on benchmarks. If O3-High costs about $350k an hour to operate, that would mean making O4 score 50% higher would cost $3.5B (!!!) an hour. That scaling wall.

No, I'm complaining that just because GPT-4 is called GPT-4 doesn't mean it's the fourth LLM from OpenAI.

Off the top of my head: GPT-2, Codex, GPT-3 in three different flavors (babbage, curie, davinci), GPT-3.5.

Suggesting that GPT-4 was "fourth" simply isn't credible.

Just the other day they announced a jump from o1 to o3, skipping o2 purely because it's already the name of a major telecommunications brand in Europe. Deriving anything from the names of OpenAI's products doesn't make sense.

The value of synthetic data relies on having non-zero signal about which generated data is "better" or "worse". In a sense, this what reinforcement learning is about. Ie, generate some data, have that data scored by some evaluator, and then feed the data back into the model with higher weight on the better stuff and lower weight on the worse stuff. The basic loop is: (i) generate synthetic data, (ii) rate synthetic d…

But who rates the synthetic data? If it is humans, I can understand that this is another way to get human knowledge into it, but if it's rated by AI, isn't it just a convoluted way of copying the rating AI's knowledge?

This is the bit I've never understood about training AI on its own output; won't you just regress to the mean?

It’s more like saying “the Audi Quattro, the company’s fourth car…”

Wait a few month and they will have a distilled model with the same performance and 1% of the run cost.

The issue isn't the grammar. It is that there are 5 distinct LLMs from OpenAI that you can use right now as well as 4 others that were deprecated in 2024.
