You’re right. That’s it!

This guy found the original.

It was originally about Napster / Gnutella.

Definitions are tricky, and especially for terms that are broadly considered virtuous/positive by the general public (cf. "organic") but I tend to deny something is open source unless you can recreate any binaries/output AND it is presented in the "preferred form for modification" (i.e. the way the GPLv3 defines the "source form").

A disassembled/decompiled binary might nominally be in some programming language--suitable input to a compiler for that langauge--but that doesn't actually make it the source code for that binary because it is not in the form the entity most enabled to make a modified form of the binary (normally or original author) would prefer to make modifications.

Russia wasn't his final destiny. He was en route to somewhere else when his passport was revoked.

also they aren't actually open source? Only the weights are open source?

This is probably the best explanation I've seen so far and really helped me actually understand what it means when we talk about "weights" for LLMs.

Just stay far, far away from their forums.

I'm not too informed about DeepSeek. Is it real open-source, or fake open-source?

It’s semi-open, not fully open source as what is typically thought of.

That sounds like fake open-source. Can I download the source, build it, have the thing run locally on my own machine, and use it without it having to interact with this company's servers?

I just looked it up.

"The AI research company DeepSeek recently released its large language model (LLM) under the MIT License, providing model weights, inference code, and technical documentation. However, the company did not release its training code, sparking a heated debate about whether DeepSeek can truly be considered "open-source."

This controversy stems from differing interpretations of what constitutes open-source in the context of large language models. While some argue that without training code, a model cannot be considered fully open-source, others highlight that DeepSeek’s approach aligns with industry norms followed by leading AI companies like Meta, Google, and Alibaba."

So fake open-source.
