Community to discuss about Llama, the family of large language models created by Meta AI.
Yi is not trustable on standard benchmarks because they are easy to game by including them in training data and the LKF gang who built this has a high pressure to justify their 1 billion dollar valuation and continue to milk investors.
The only way to really evaluate this is on some hidden benchmark never seen before and / or rigorous qualitative experiments.
Until then, I’m not holding my breath.
I believe they said they’re going to release training data. We’ll see. That’s about the only way to easily verify what made it in.
I have trained book3 for 1 day on a number of GPUs on the 200k, 34B & 6B, it is totally garbage.
It is not a BASE model at ALL. It even knows itself as GPT sometimes. It was a SFT model on format of benchmarks.
Try it before you do silly things, you would not find it on SFT immediately, but sooner or later.
It referring to itself as a GPT could just be from pre-training internet data if it was trained on internet data from 2023.
It sounds rather like it trained on chatGPT output and they didn't curate it enough to delete those "As a large language model trained by openAI..." category statements.
It's kinda like Shutterstock watermarks showing up in image generation.
Yea I’m saying that ChatGPT outputs are contained on internet posts in the year 2023, so simply training from 2023 internet data would end up with training on ChatGPT data as a side effect.
Yes, I understood you. My claim differs in that I think they DIRECTLY used a lot of GPT4 output through the api, which is very probable because a lot of LLM training is done that way. You ask GPT4 to generate examples of conversations with properties you want your LLM to learn and then train on that.
In order for self identification, as GPT I don’t think that randomly crawled chat Examples from the Internet would be enough.
I am not trying to make a strong claim on that, it’s just a thought. My people both.
The regular 34b "feels" like it ignores my prompt a lot.
It's supposed to be a base model and not Instruction finetuned model. That's how base models generally behave unless they are sold as base but actually finetuned (llama 2 base models).
I felt this too. It seems to "grab on" when you give it a longer context to continue though.
I am running my story on 200K, feels the same as 4K to me (which I tried in the same setting before 200K was released).
And honestly... Even if it is much worse (and I dont think it worse at all), the mega context is such a boon for storytelling.
What I did not try was 4K stretched out with RoPE alpha or anything like that, but the 200K model does not need any stretching out to at least 42K.
The normal Yi model can go up to 32K btw
In most scenarios, models with extended context are optimized for long sequences. If the sequence is not very long, it is often recommended to use a regular model
Doctor Shotgun has made some Yi-34bs with Airoboros and LimaRP. You might want to talk with them and try out their version. Measure twice and cut once, as they say.
Random update on this, I did some more experimenting on the start of a story (with LimaRP and Petrol LoRAs), and the 4K model seems... fine? So does the 200K.
I don't how know to stretch out the base model. Their page claims it supports 32K, but it has a 4K context in the config and no RoPE scaling section. Just a high rope theta.
The one difference I did notice is that the 200K model really likes to summarize and reference previous parts of the story. Maybe it was trained on retrieval or summarization examples.
How are such models finetuned ? Is finetuning are retraining similar ?
