containing concise 2-4 sentence summary. Then a link to original source: Read original. Use the URL from news: https://www.reddit.com/r/LocalLLaMA/comments/1uotkm7/new_model_gigachat35432ba28b_with_day0_gguf/. Summarize: new model GigaChat3.5-432B-A28B from Sberbank, includes day-0 GGUF support, available on Hugging Face, base version, and a PR for llama.cpp. Make 2-4 sentences. Let's craft: "Sberbank released the GigaChat3.5-432B-A28B model with day‑0 GGUF support, now hosted on Hugging Face alongside its base version. The GGUF format is provided via a community PR to llama.cpp, though it isn’t yet merged into the main branch." That's 2 sentences. Then link. Check rules: must be concise, 2-4 sentences. Use precise technical language. No invented info. Use only provided. The description says "New model from Sberbank". Also "For now it's not in master branch yet but one can build from this PR". So summarizing that is fine. Now output only HTML. Ensure
