"64K tokens context window" I do wish they had managed to extend it to at least 128K to match the capabilities of GPT-4 Turbo Maybe this limit will become a joke when looking back? Can you imagine reaching a trillion tokens context window in the future, as Sam speculated on Lex's podcast?

Why do we expect this to perform better? Couldn’t a regular network converge on this structure anyways?
Here's my naive intuition: in general bigger models can store more knowledge but take longer to do inference. MoE provides a way to blend the advantages of having a bigger model (more storage) with the advantages of having smaller models at inference time (faster, less memory required). When you do inference, tokens hit a small layer that is load balancing the experts then activate 1 or 2 experts. So you're storing r…

#165Does anyone have a good layman's explanation of the "Mixture-of-Experts" concept? I think I understand the idea of having "sub-experts", but how do you decide what each specialization is during training? Or is that not how it works at all?
Ignore the "experts" part, it misleads a lot of people [0]. There is no explicit specialization in the most popular setups, it is achieved implicitly through training. In short: MoEs add multiple MLP sublayers and a routing mechanism after each attention sublayer and let the training procedure learn the MLP parameters and the routing parameters. In a longer, but still rough, form... How these transformers work is rou…

#166Dumb question: Are "non-instructed" versions of LLMs just raw, no-guardrail versions of the "instructed" versions that most end-users see? And why does Mixtral need one, when OpenAI LLMs do not?

LLM’s are first trained to predict the next most likely word (or token if you want to be accurate) from web crawls. These models are basically great at continuing unfinished text but can’t really be used for instructions e.g. Q&A or chatting - this is the “non-instructed” version. These models are then fine tuned for instructions using additional data from human interaction - these are the “instructed” versions which…

That's for an 8B model.
This is over trivializing it, but there isn't much more inherent complexity in training an 8B or larger model other than more money, more compute, more data, more time. Overall, the principles are similar.
