Open Weights Aren't Open Source: Aether-7B-5Attn, a From-Scratch Fully-Open Foundation Model (Apache-2.0)
Article summary
Quick briefing — cleaned from the original RSS feed
A from-scratch, fully-open foundation model (Apache-2.0): Aether-7B-5Attn Most "open" LLMs ship one thing: a weights file. That's the compiled binary of an LLM. The training data, the training code, the hyperparameters, the logs — all closed. By the software definition of "open source," that's just a published binary. VIDRAFT released Aether-7B-5Attn the other way. Under Apache-2.0, it opens the whole manufacturing process: architecture source (attention + MoE + Latin square) data recipe —…
