Drop a .gguf and OmniViewer reports the model’s technical
shape: the parameter count, the file size and the effective
bits per weight, the layer and
expert count, the context length, the number of tensors and
the quantization mix across the whole file. It reads the
header only, so it’s instant and entirely local.
Stats are the quick way to size up a model — how big, how quantized, how deep — before you download or run it. The same drop also shows the architecture card, the metadata, the tensors and the tokenizer.
It’s one lens on OmniViewer’s GGUF Viewer — Inspect LLM Model Files: drop a file and every tab is one click away. OmniViewer opens every file format, entirely in your browser — no upload, no server.
No. OmniViewer is a static page with no server-side processing: your .gguf is read directly by your browser, and every tab — architecture, metadata, tensors, tokenizer and stats — runs locally in a Web Worker. The model never leaves your computer.
GGUF keeps all of its metadata and its tensor table at the front of the file, before the weights. OmniViewer reads only that header prefix — a few megabytes at most — and never reads the multi-gigabyte weight body, so a 40 GB model opens as fast as a small one.
A lot, with no description file: the architecture, the parameter count (computed from the tensor shapes), the quantization and effective bits-per-weight, the number of layers, the embedding and context length, the attention type (multi-head, grouped-query or multi-query), the Mixture-of-Experts configuration, the RoPE settings and the embedded tokenizer including its chat template.
Yes. When the header carries an expert count (as Mixtral and other MoE models do), the architecture card shows how many experts the model has and how many are routed per token — for example, 8 experts with 2 active.
Bits-per-weight is the average number of bits each parameter takes on disk — a direct measure of how aggressively the model is quantized. OmniViewer computes it as the file size in bits divided by the parameter count (summed from the tensor shapes), so a Q4_K model comes out around 4.5 bits per weight.
All the common GGML tensor types, including F32, F16 and BF16 and the quantized types Q4_0, Q4_K, Q5_K, Q6_K, Q8_0 and the IQ family. The Tensors tab shows the exact mix, and the Architecture card names the dominant one.
Yes. OmniViewer parses the GGUF structure in pure JavaScript, so it works in any modern browser on Windows, Linux, macOS or a phone. No llama.cpp, no Ollama, no Python, no install.
