🌟 Gemma 4 Is Here — And My C# Library Is (Almost) Ready

This article discusses the release of Google's Gemma 4 open model family and the author's progress in updating their C# library, ElBruno.LocalLLMs, to support it. It covers Gemma 4's architecture, including Per-Layer Embeddings (PLE), model variants (E2B IT, E4B IT, 26B A4B IT, 31B IT), and features like chat templates and tool calling. The library is almost ready with model definitions, chat templates, and tests passing, but ONNX conversion is blocked due to runtime limitations. The article is technical, focused on software development and AI integration.
