Which model? Give full command line you started this is useful.

Here is the command I used.

/data/local/tmp/llama-cpp/bin/llama-cli -m /data/local/tmp/models/models-gguf/mistral-7b-instruct-v0.1.Q4_K_M.gguf --interactive --conversation --prompt "Hello, how can I help you today?"

Ok, it's a older model, i found it here: https://huggingface.co/TheBloke/Mistral-7B-Instruct-v0.1-GGUF

TheBloke gives this example: -p "<s>[INST]{prompt} [/INST]"
