I'm 14, a few months ago I posted here (I think) about Plasma 1.0, an LLM trained completely from scratch on my gaming PC. Plasma 1.1 is the follow up: it has double the params, and double the training tokens at 521M params and 10B tokens. It's Llama style (26 layers, GQA, SwiGLU, RoPE), 48k custom…
