Hm, roundabout 84 authors of one "scientific" paper. I wonder if this says something about (a) the quality of its content, (b) the path were academic (?) paper publishing goes to, (c) nothing at all, or (d), something entirely else.

I have been on far larger author lists :) There's probably a whole team for the training data generation and assessment, a whole team for the safety assessment (section 4), that stuff adds up.

Incredible, rivals Llama 3 8B with 3.8B parameters after less than a week of release. And on LMSYS English, Llama 3 8B is on par with GPT-4 (not GPT-4-Turbo), as well as Mistral-Large. Source: https://chat.lmsys.org/?leaderboard (select English in the dropdown) So we now have an open-source LLM approximately equivalent in quality to GPT-4 that can run on phones? Kinda? Wild.

On par in some categories. Phi was intended for reasoning, not storing data, due to small size. I mean, it's still great, but the smaller it gets, the more facts from outside of the prompts context will not be known at all.

Can’t wait to see some Phi-3 fine tunes! Will be testing this out locally, such a small model that I can run it without quantization. Feels incredible to be living in a time with such neck breaking innovations. What are chances we’ll have a <100B parameter GPT4/Claude Opus model in the next 5 years?

We already do. It’s called LLama 3 70B Instruct.

Llama 3 is awful in non-English. 95% of their training data is in English....

GPT is still the king when talking about multiple languages/knowledge.

Yes, I don't know how people don't realize how much cheap tricks works in Chatbot Arena. A single base model produces 100s of ELO difference depending on the way it is tuned. And on most cases, instruction tuning heavily slightly even decreases reasoning ability on standard benchmark. You can see base model scores better in MMLU/ARC most of the times in huggingface leaderboard. Even GPT-4-1106 seems to only sounds be…

When I tried Phi2 it was just bad. I don't know where you got this fantasy from that people accept obviously wrong answers, because of "pandering".

Obviously correct answer matters more but ~100-200 elo points could be gained just for better writing. Answer would be range of 500 elo in comparison.

This won't dethrone Llama 3, but it's equally impressive. They mention this model's relative weakness in the TruthfulQA eval, since it's more lossy trying to pack 'knowledge' into a small model relative to problem-solving skills (which shine on MMLU) Regardless - still a very useful thing to have offline and on the fly. Those scores are nothing to scoff at. Given that these pipelines are likely harder harder to imita…

> TruthfulQA Wait, people still use this benchmark? I hear there's a huge flaw on it. For examples, fine-tuning the model on 4chan make it scores better on TruthfulQA. It becomes very offensive afterwards though, for obvious reasons. See GPT-4chan [1] [1] https://www.youtube.com/watch?v=efPrtcLdcdM

Couldn't it be that training it on 4chan makes it more truthful for some reason?

Just means you need a big machine and a lot of capital to make advancement. Take a look at any paper coming out of cern.

At a glance, it looks like Phi-3 was trained on an English only, STEM-strong dataset. See how they are not as strong in HumanEval, Trivia, etc. But of course it's very good.

Where did you get this from?

> So we now have an open-source LLM approximately equivalent in quality to GPT-4 that can run on phones

No, not even close ... Even Gemini has huge UX gap comparing to GPT4/Opus, 8B I won't even attempt this argument.

It's a tech report. Fair enough to include the whole lab.
