How is the capex on 8 * MI354X even remotely justified at less than $10/h?

Even without the base system, power and every other expenses: 365d * 24h * $2.95 = $25842/a invoicable.

That doesn't add up within one year, that doesn't add up in three years and it is questionable that it brings in the money during the lifetime of the device?

It's like saying binaries are the preferred way of modifying program because you can't afford to have a fast enough machine to compile it yourself. Most people don't have resources to compile their own brow…

No, it's the preferred way because that's literally how you train it. Contrary to popular misconceptions, you don't "compile" data into weights. You initialize a model (based on architecture, config, etc) and then you modify it via training. But crucially they (i.e. model creators) modify it the same way (technically speaking) as you would. That's what the license grants you. Nothing less, nothing more. The "how" as in knowhow has never been something covered by a license.

Open-weight is something dreamt up by people misunderstanding the basics of model creation and training, and having ideological biases against AI and/or LLMs. It is what it is, but you should know that you are technically wrong. A model released under an open source license (Apache, MIT, etc) is an open source model. Because the weights are the source of the models. Training is not "compilation". Training is the "how" as in knowhow to modify the model. Training deals with values. Source deals with everything, including values.

In the past, if someone would have released a piece of software (say a PID controller algo) w/ hardcoded values, no-one would bat an eye. LLMs are just that, with billions of hardcoded values. Nothing less nothing more.

That can’t be real. Modal rents out an RTX 6000 Pro for more than that. Nvidia will rent your GPUs at a fixed cheap rate if you buy from them. Perhaps AMD has a different subsidy style program. Because those MI355X are going cheap here.

I think you are failing to see how the weights are the preferred form of working with a model. It's like if I shared a png with others to use as a meme template. Even if I don't share the source code to photoshop other people can use that "binary file dump" to make derivative images of their own with it.

Per the OSD definition of source code, "the source code must be the preferred form in which a programmer would modify the program." which means an argument could be made (as charcircuit is making) that the weights, being the preferred form to modify, are the source. I do prefer open weights as being more precise (like, is it even really software that has source code in the first place?) but I feel like at this point…

You can also edit/patch binary executables, but no one says about that software that is open source.

I wish they wouldn't call them "open source models". They aren't open source. They didn't publish the training data. They didn't publish the tools they used to train the model. They published the weights. It's an "open weight model", a term that it seems nearly everyone has agreed is appropriate. Why is this company not using it?

If they open sourced the training data and code but you had to train the network yourself, would that be open source?

Yes, obviously.

Even though none of us could actually afford to train it?

Where do you see less than $10/h for 8 * MI354X? I can only find $2.50 for 1 * MI355X (lowest I can find for rent on other websites is $2.65, but maybe they got a better deal).

Is anyone actually renting them out that cheap? The very cheapest on-demand price I see online is $14, and most providers are a lot higher

Some of us might be rich, or get funding, or in the future it could be useful when training is cheaper.

Open source has benefits even if you can run yourself. You can read the code for understanding/insights. Other labs could replicate/build on it.
