Which apps can open a model depends on the files published for it: GGUF for llama.cpp-based apps, MLX for Apple’s engine, the original weights for vLLM and SGLang. Compare every app.

Memory needed

Weights plus KV cache and runtime overhead. Leave a little extra free for the operating system and other apps. Try another context length.

KV cache: compressed KV cache shared across layers: only 4 of 40 layers write a growing cache (a single 512-value latent; 3 of them store one latent per 2 tokens) and the other layers read it, alongside a 128-token sliding window in every layer; estimate treats it like a latent cache.
