Features

• Fast and light CLI with a single installable binary
• Fetches just the required bytes from the safetensors files on the Hugging Face Hub that contain the metadata
• Provides an estimation based on the count of the parameters on the different dtypes
• Supports both sharded i.e. model-00000-of-00000.safetensors and not sharded i.e. model.safetensors files

What's next?

• Add tracing and progress bars when fetching from the Hub
• Support other file types as e.g. gguf
• Read metadata from local files if existing, instead of just fetching from the Hub every single time
• Add more flags to support estimations assuming quantization, extended context lengths, any added memory overhead, etc.
