Frequently asked questions
What is an open-weight LLM?
An open-weight LLM is a model whose trained weights are publicly available for download, letting you self-host, fine-tune, and inspect it. This differs from fully open-source (which also releases training code and data) and from closed API-only models.
What is the best open-weight LLM?
Among open-weight models in our dataset, Llama 4 Scout 17B Instruct (US) ranks highly on context window and pricing. The best choice depends on your hardware budget and task.
Can I run open-weight LLMs locally?
Yes — open-weight models can run on your own GPUs or via inference providers. Smaller models run on a single GPU; larger ones need multi-GPU setups or quantization.
