I'm curious about their business model.

Well so far their business model seems to be mostly centered about raising money[1]. I do hope they succeed in becoming a succesful contender against OpenAI. [1] https://www.bloomberg.com/news/articles/2023-12-04/openai-ri...

Still 7B, but now with 32k context. Looking forward to see how it compares with the previous one, and what the community does with it.

Not 7B, 8x7B. It will run with the speed of a 7B model while being much smarter but requiring ~24GB of RAM instead of ~4GB (in 4bit).

No public statement from Mistral yet. What we know: - Mixture of Experts architecture. - 8x 7B parameters experts (potentially trained starting with their base 7B model?). - 96GB of weights. You won't be able to run this on your home GPU.

> - 96GB of weights. You won't be able to run this on your home GPU.

You can these days, even in a portable device running on battery.

96GB fits comfortably in some laptop GPUs released this year.

>> You won't be able to run this on your home GPU. Would this allow you to run each expert on a cheap commodity GPU card so that instead of using expensive 200GB cards we can use a computer with 8 cheap gaming cards in it?

Yes, but you wouldn't want to do that. You will be able to run that on a single 24gb GPU by the end of this weekend.

looks like they're too busy being awesome. i need a fake video to understand this!

What memory will this need? I guess it won't run on my 12GB of vram

"moe": {"num_experts_per_tok": 2, "num_experts": 8}

I bet many people will re-discover bittorrent tonight

Looks to be Mixture of Experts, here is the params.json: { "dim": 4096, "n_layers": 32, "head_dim": 128, "hidden_dim": 14336, "n_heads": 32, "n_kv_heads": 8, "norm_eps": 1e-05, "vocab_size": 32000, "moe": { "num_experts_per_tok": 2, "num_experts": 8 } }

What does expert mean in this context?

I'm sure it's also a marketing move to build a certain reputation. Looks like it's working.

Not geoblocking the entirety of Europe also makes them stand out like a ringmaster amongst clowns.

Well they are French after all. They should be geoblocking the USA in response for a bit to make a point lol.

Be a lot cooler if you said what laptop, and how much quantisation you're assuming :)

What does expert mean in this context?

It means it's 8 7B models in a trench coat in a sense, it runs as fast as a 14B (2 experts at a time apparently) but takes up as much memory as a 40B model (70% * 8 * 7B). There is some process trained into it that chooses which experts to use based on the question posed. GPT 4 is allegedly based on the same architecture, but at 8*222B.
