# MiniCPM5-1B-Agent demo Space - llama.cpp server (Q8_0 GGUF) + the agent-loop UI (app.py).
# Based on the proven usermma/MiniCPM-5-Q4 pattern (FROM ghcr.io/ggml-org/llama.cpp:full), but instead
# of the raw chat UI we run app.py, which starts llama-server itself and drives the write->run->verify loop.

# model repo (MODEL_REPO/tokenizer) so the tokenizer lives in exactly one place (the GGUF repo, with the model).
