A developer has released OpenArch, a repository of hand-written PyTorch implementations of modern open-source LLM architectures, cataloged against Sebastian Raschka's LLM Architecture Gallery. The pro…
A developer ran GPT-2 XL (2019) and Qwen3-0.6B (2025) locally on the same laptop through AMD's Lemonade server, finding a 11x speed gap after correcting measurement errors. The project, called Second …
Researchers introduced TreeTracer, a visual analytics tool that aggregates hundreds of stochastic LLM generations into syntax-aligned trees to expose hidden biases. The tool uses perturbation analysis…
Researchers at arXiv (arXiv:2605.23035) used sparse autoencoders to decompose GPT-2 XL and Llama-3.1-8B into 16K-32K interpretable features per layer, finding that semantic features alone recovered 94…
Researchers decomposed GPT-2 XL and Llama-3.1-8B into 16,000 to 32,000 interpretable features per layer using sparse autoencoders, finding that semantic features alone recovered 94% of peak brain-resp…
