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.

Not with their cap table, they won't ;-)

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 like it will squeeze into 24GB once the llama runtimes work it out.

Its also a good candidate for splitting across small GPUs, maybe.

One architecture I can envision is hosting prompt ingestion and the "host" model on the GPU and the downstream expert model weights on the CPU /IGP. This is actually pretty efficient, as the CPU/IGP is really bad at the prompt ingestion but reasonably fast at ~14B token generation.

Llama.cpp all but already does this, I'm sure MLC will implement it as well.

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.

unfortunately too big for the broader community to test. Will be very interesting to see how well it performs compared to the large models

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.

That is only 24GB in 4bit. People are running models 2-4 times that size on local GPUs. What's more, this will run on a MacBook CPU just fine-- and at an extremely high speed.

Yeah, 70B is much larger and fits on a 24GB, admitedly with very lossy quantization.

This is just about right for 24GB. I bet that is intentional on their part.

> You won't be able to run this on your home GPU.

As far as I understand in a MOE model only one/few experts are actually used at the same time, shouldn't the inference speed for this new MOE model be roughly the same as for a normal Mistral 7B then?

7B models have a reasonable throughput when ran on a beefy CPU, especially when quantized down to 4bit precision, so couldn't Mixtral be comfortably ran on a CPU too then, just with 8 times the memory footprint?

Not really, looks like a ~40B class model which is very runnable.

I don't see any code in there. What runtime could load these weights?

Its presumably llama just like Mistral. Everything open source is llama now. Facebook all but standardized the architecture. I dunno about the moe. Is there existing transformers code for that part? It kinda looks like there is based on the config.

Mistral is not llama architecture.

Because it's JSON? :)

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

They're probably referring to the new MacBook Pros with up to 128GB of unified memory.
