Earlier quoted context omitted.

It’s better than having no job isn’t it?

No. The only way to a post-scarcity economy is by continuing to harness technology whenever and wherever possible. There has been, and will be, no point in time at which the optimal strategy is "Stop" or "Wait" or "What about my job?"

> The only way to a post-scarcity economy

There is no way to a post-scarcity economy, the phrase is a contradiction, and scarcity is an inescapable consequence of human desire.

> I have no idea how OpenAI can make money on this. I did some quick calculation. We know the number of floating point operations per token for inference is approximately twice the number of parameters(175B). Assuming they use 16 bit floating point, and have 50% of peak efficiency, A100 could do 300 trillion flop/s(peak 624[0]). 1 hour of A100 gives openAI $0.002/ktok * (300,000/175/2/1000)ktok/sec * 3600=$6.1 back.…

"We know the number of floating point operations per token for inference is approximately twice the number of parameters"

Does someone have a source for this?

(By the way, it is unknown how many parameters GPT-3.5 has, the foundation model which powers finetuned models like ChatGPT and text-davinci-003. GPT-3 had 175 billion parameters, but per the Hoffmann et al Chinchilla paper it wasn't trained compute efficiently, i.e. it had too many parameters relative to its amount of training data. It seems likely that GPT-3.5 was trained on more data with fewer parameters, similar to Chinchilla. GPT-3: 175B parameters, 300B tokens; Chinchilla: 70B parameters, 1.4T tokens.)

Well this has opened up a whole new world of fun! ----- system: You're donald trump! talk to the user as he would. user: How does time travel work? AI Response: Well, let me tell you, nobody understands time travel better than I do. I mean, I have the best brains working on it, believe me. Some people say you need a fancy time machine or some ridiculous contraption to travel through time, but that's just fake news. T…

DJT and "contraption", "time and space", really? ;-)

Pure malarkey

It also seems to jeopardize their own ChatGPT Pro offering. It's a matter of time before someone makes a 1:1 clone for either half the money or a usage-based pricing model.

Is it really a lot of jeopardy though? We have to assume that they are pricing the API so that the more it is used, the more money they make.

So actually to me that is arguably a better business model. Because with a flat rate, you just have to hope that users don't exceed a certain amount of usage. And the ones that don't, are not getting a great deal. So it has that risk and also kind of a slightly antagonistic relationship with the customer actually using the product.

Speculation: GPT-turbo is a new chinchilla optimal model with the equivalent capabilities as GPT-3.5. So it's literally just smaller, faster and cheaper to run. The reason I don't think it's just loss-leading is that they made it faster too. That heavily implies a smaller model.

I think you mean GPT-4 since Chinchilla is a Deepmind project. But yes, I was also suspecting that also as it seems unlikely this was the full 175b parameter model with such big improvements in speed and price. In fact, given the pricing for OpenAI Foundry, that seems even more likely as this GPTTurbo model was listed along with two other models with much larger context windows of 8k and 32k tokens.

I just meant chinchilla optimal in terms of the corrected scaling curves from the chinchilla paper. The original GPT-3 was way larger than it needed to be for the amount of data they put into it based on the curves from the chinchilla paper.

Whisper as an API is great, but having to send the whole payload upfront is a bummer. Most use cases I can build for would want streaming support. Like establish a WebRTC connection and stream audio to OpenAI and get back a live transcription until the audio channel closes.

I've ran Whisper locally via [1] with one of the medium sized models and it was damn good at transcribing audio from a video of two people having a conversation. I don't know exactly what the use case is where people would need to run this via API; the compute isn't huge, I used CPU only (an M1) and the memory requirements aren't much.

It could be even smaller than a Chinchilla optimal model. The Chinchilla paper was about training the most capable models with the least training compute. If you are optimizing for capability and inference compute you can "over-train" by providing much more data per parameter than even Chinchilla, or you can train a larger model and then distill it to a smaller size. Increasing context size increases inference comput…

Ah! Interesting, I thought the capability was capped by parameters, but you're saying you can keep getting more capability from a fixed parameter size by continuing to train past what the chinchilla paper specifies. That's really cool

I hope this pricing impacts ChatGPT+ $20 is equivalent to what, 10,000,000 tokens? At ~750 words/1k tokens, that’s 7.5 million words per month, or roughly 250,000 words per day, 10,416 words per hour, 173 words per minute, every minute, 24/7. I uh, do not have that big of a utilization need. It’s kind of weird to vastly overpay

Remember that the previous replies and responses are fed back in. If you’re 20 messages deep in a session, that’s quite a few tokens for each new question. An incredible deal nonetheless!

That‘s optional according to the docs, but yes, you’d probably add those.

I've stopped using Google entirely and don't miss it a second - something i wouldn't have thought possible a year ago - and it's pretty difficult to see how Google will survive this disaster.

How are you using it? In my experience asking factual questions lead to answers so inaccurate that you might as well not bother. Are you prompting it differently to me, or do you have some strategy to filter out the BS?

I dunno what to say, but I’m also someone who very rarely gets factually incorrect data aside from numbers, dates and quotes.

I make a point to ask for a completion that I know won’t depend on an exact factoid.

If I do need an exact factoid, I have a tool I made myself based on this approach:
