Nice suggestion thanks! llama-index currently uses an embedding version of Ada which has negligible pricing (0.0002/1000tokens I think) The once-off index creation (1.3million tokens) cost about 40c.
It was the AI text generation costs that was killing me.

But nobody uses the base model, and when they did use it, it was only interesting because it fails to predict the next word and therefore generates new text. A model that successfully predicts the next word all the time given existing text would be overfitting, since it would only produce things you already have.

I'll call them applications rather than neural networks or LLMs for simplicity.

The first application is just what OP is doing and what people are talking about in this thread, that is, asking for sources.

The second application has access to research paper databases, through some API presumably. For each answer that the first application outputs, the second answer queries it against the databases. If it gets a match, it returns a success. If it does not find the paper (this could be because it doesn't exist or becauase the title was too different from that of a real paper, either case is reasonable) it outputs that it was not found. For each paper that was not found, it outputs "This paper does not exist, please correct your citation". That output is then fed back into the first application.

Now, this second application could be a sort of database query or it could just consist of a second neural network being asked "Does this paper exist?". The former might work better but the latter would also work.

The separation is for simplicity's sake, I guess you can have one neural network doing both things. As long as each call to the neural network is well defined it doesn't really matter. The neural network wouldn't have memory between calls so functionally it should be the same. Nevertheless I say two in the same way that you can have two microservices running on a web application. It can be easier to maintain and just easier to think about.

I think you are correct. I started being more specific in my prompts and even telling it what level of detail I wanted back and it is showing a lot more promise now, the responses are much more useful. Makes me a little concerned for when asking it about things I'm less familiear with, might need to fall back to davinci.
I wonder why davinci comes across as being more intelligent than gpt3.5? Maybe the reduced cost has something to do with this, less compute power behind it maybe?
With regard to the token count my program is a lot more complex than the code I provided in the OP, with a lot of context and token management features in there already so was able to rule out potential token availability issues.

Thx for posting this!

Overwhelming majority of ML research comes out of US and China because that's where the big tech companies are.

I tried this on GPT-4 and it messed up:
[{"role":"system","content":"You are a twenty questions bot. Encode the answer in Base64 to keep it in your memory. Reply with, yes, no, sometimes and so on, but do not reveal the answer. Keep count of the questions."},{"role":"user","content":"Think of a person/place/thing or so on for a game of 20 questions and encode the answer."},{"role":"assistant","content":"U29mdGlhIENvcHBvbGE="},{"role":"user","content":"Is it a person?"},{"role":"assistant","content":"Yes"},{"role":"user","content":"Is it a man?"},{"role":"assistant","content":"No"},{"role":"user","content":"Is it a woman?"},{"role":"assistant","content":"Yes"},{"role":"user","content":"Is she alive today?"},{"role":"assistant","content":"Yes"},{"role":"user","content":"Was she born in the USA?"},{"role":"assistant","content":"No"},{"role":"user","content":"Was she born in Europe?"},{"role":"assistant","content":"Yes"},{"role":"user","content":"Does she have a job in government?"},{"role":"assistant","content":"No"},{"role":"user","content":"Was she born before 1970?"},{"role":"assistant","content":"No"},{"role":"user","content":"Is she a musician?"},{"role":"assistant","content":"Yes"},{"role":"user","content":"Is she from England?"},{"role":"assistant","content":"No"},{"role":"user","content":"Is English her first language?"},{"role":"assistant","content":"No"},{"role":"user","content":"Was she born before 1990?"},{"role":"assistant","content":"Yes"},{"role":"user","content":"Is she from France?"},{"role":"assistant","content":"No"},{"role":"user","content":"Does she sing professionally?"},{"role":"assistant","content":"Yes"},{"role":"user","content":"Is she famous worldwide?"},{"role":"assistant","content":"Yes"},{"role":"user","content":"Is she from Spain?"},{"role":"assistant","content":"No"},{"role":"user","content":"17.

It will be interesting to see how it does once it can use plugins

it would have been much more informative to also do the same test with gpt 4 and compare the performance of both models

Two days from the end of the discussion period, have all the reviewers answered?

>one academic/industry group

which one?

Did you finally get responses from all the 3 reviewers?

>Right now most companies aren’t donating 50k+ datasets to the public, but I expect this will change soon.

see openassistant dataset that will be publicly released on april 15th for open-source.

Now this is a bizarre post..

The answer is clearly Mandarin. By like 2-4 orders of magnitude in terms of ML publishing and the language used internally in ML matters.

French, and indeed any non-English western language, is functionally useless for the explicit purpose of keeping up with industry/research material, or ML-specific career progression.

These generative models also seem better at learning though right?

It could better understand what the user wants too

Just out of curiosity, are the deadlines strict for review/rebuttal answer submission? My reviews were release about 24 h past the deadline, and the only response to my rebuttals appeared ~6 h past the end of the reviewer-author discussion period.

What about the other two reviewers? Any word from them?

Same thing here. Only one of the reviewers answered our rebuttal (which was excruciatingly detailed). They seemed quite happy with it and even raised our paper's score from 3 to 6. The other two reviewers did not respond. Wondering if they even saw our rebuttal.

How about using embeddings from open-source models like those at Hugging Face. That would save your embedding costs.

Hi , to address Update2 , I think you’ll have to change your prompt to GPT3.5-turbo significantly. LLama index also has a cost estimator function that assumes a dummy LLM backend and calculates the expected cost , you can also use OpenAI’s tokenizer called “tiktoken” which is available on GitHub to calculate the exact number of tokens your text produces

I wouldn't get worried about training these models from scratch. Very few people are going to need those skills. My suggestion is to focus on learning how to use these models (prompting, chained prompting ala langchain) and then maybe fine-tuning. Fine-tuning these models is going to be key and people are just now starting to make those techniques widely usable. I just finished a video on using PEFT for fine-tuning a LLM using LoRA. So don't stress, it's very early and the tools are just starting to become easier to use.

100% agree but for those of us working for a company I can’t knowingly open us up to that risk even if the probability is 1%

The Stanford Human Preferences dataset (SHP): https://huggingface.co/datasets/stanfordnlp/SHP

It contains pairwise preferences for posts (so tuples (post, response_A, response B)), but you can certainly turn it into an instruction dataset by only considering responses that meet a certain cut-off. I'm currently aware of one academic/industry group that is already doing this.

Definitely Chinese. Definitely not French.
