LLM Architecture Gallery Diff Tool

This article announces updates to the LLM Architecture Gallery, focusing on a new architecture diff tool. The tool allows users to select two models and compare their architecture stacks side by side, highlighting differences in attention blocks, decoder type, KV-cache footprint, layer recipe, model scale, and context length. It is designed for cases where models appear similar but differ in critical details, such as DeepSeek V3 versus V3.2. The tool can be accessed via selectors or gallery card actions. This is a technical update relevant to AI/ML architecture analysis and tooling.
