llmfit review covering its local LLM VRAM, quantization, context, and RAM calculators, practical uses, limitations, pricing uncertainty, and alternatives.
What llmfit is
llmfit is a focused website for estimating which local language models fit a particular machine. Its live site exposes four tools: a VRAM calculator, a “What Can I Run?” GPU recommender, a context-length calculator, and a system-RAM calculator aimed at CPU and memory-heavy inference. The vendor says its calculations are checked against real local inference setups rather than relying only on theoretical parameter arithmetic. This is a planning utility, not an inference engine: it does not download, serve, benchmark, or evaluate a model for you.
