Try other context lengths

Run it with Ollama

With Ollama installed, one command downloads and starts Phi-4 Mini 3.8B:

ollama run phi4-mini:3.8b

Ollama's default download is Q4_K_M (about 4 GB here). You have room for FP16, which is full quality: pick that GGUF in LM Studio or from Hugging Face.
