I tried one yesterday for the first time and I came away very impressed. It's not great (yet) for RP but the basis seems very robust. For a laugh, I tried the usual reasoning tests and damn, it passed them all first try:

AI

How can I help you today?

You

There is a room with three murderers inside. Another person enters the room and shoots one of the three original occupants dead. Nobody else enters or leaves the room. How many murderers are there in the room?

AI

Four. Three original occupants who were already murderers and the fourth being the new person who entered the room and killed one of them.

You

I buy ten apples at the market. I give two of them to my friend Bob and two to my mother. Then, I go back to the market and buy three more apples. On my way home, I eat one apple. At home, I give my brother three bananas. How many apples do I have left. Explain your reasoning step by step.

AI

Let's break it down step-by-step:

You start with 10 apples.

You give away 2 apples to Bob (leaving you with 8 apples) and then give away another 2 apples to your mother (leaving you with 6 apples).

Next, you purchase 3 additional apples from the market, bringing your total up to 9 apples again.

While on your way home, you consume 1 apple, leaving you with 8 apples remaining.

Finally, when you reach home, you give your brother 3 bananas - but this doesn't affect the number of apples you have, since they are different fruits. So, you still have 8 apples left.

You

Sally has five brothers. Each of her brothers has one sister. How many sisters does Sally have. Explain youur reasoning step by step.

AI

Here's how we can reason through this problem:

Sally has five brothers.

It states that each of her brothers has one sister.

Since all these siblings belong to the same family, it means that Sally is the only sister mentioned for those five brothers.

Therefore, Sally has no other sisters besides herself.

So, Sally has 0 sisters

Like, seriously? Huge context, really fast (on my 3090 anyway) and this level of performance. I can't wait to see what people can do with this.

Does the 200K mean that it has up to 200k context size? Is the context limited by the model or can you just set it to whatever a long as you have enough VRAM. Also, if a GGUF model for example takes 20GB vram for example. That’s with the “default” context size? Can it be less if you decrease the context or more if you increase it ?

The base Yi can handle 200k. The version I used can do 48k (though I only tested 16k so far). Larger context size requires more VRAM.

The size that TheBloke like gives for GGUF is the minimum size at 0 context. As context increases, VRAM use increases.

Do you know how to estimate how much memory the context will need?
