Original GitHub issue: https://github.com/ollama/ollama/issues/10994

When using Ollama to load the Unsloth Qwen3-14B-GGUF model (hf.co/unsloth/Qwen3-14B-GGUF:Q4_K_M), the memory usage spikes to 34 GB, while the standard Ollama version of the same model (qwen3:14b, also Q4_K_M) only uses around 10 GB.

The unsloth models usually have an embedded num_ctx in the Modelfile. Remove it and the memory use will be reduced.
