This is the new OSI Open source definition for AI models:
https://opensource.org/ai/open-source-ai-definition
Mistral Large 4 is definitely not open given the "use for any purpose without having to ask for permission" requirement.
Well, to be fair, Mistral never say its open source. They call it just open weight.
Not really. That definition also requires the training code and training data composition to be open-sourced.
No major Chinese or Western labs satisfy these requirements. The only vendors I can think of that do are Nvidia and Allen AI.
K2 horizon is the closest to actually releasing everything that I am aware of https://ifm.ai/blog/k2/
Also Apertus: https://apertus-ai.org/
Allen AI imposes further restrictions on their model releases, I think: https://allenai.org/responsible-use
Nobody can do that because they were all trained on stolen content
I think IBM's Granite LLM are claimed to be trained only on legally-obtained data
