I just added Llama 2 support to my LLM CLI tool: https://simonwillison.net/2023/Jul/18/accessing-llama-2/

So you can now access the Replicate hosted version from the terminal like this:

    pip install llm
    # or brew install simonw/llm/llm
    llm install llm-replicate
    llm keys set replicate
    # Paste in your Replicate API key
    llm replicate add a16z-infra/llama13b-v2-chat \
      --chat --alias llama2
    # And run a prompt
    llm -m llama2 "Ten great names for a pet pelican"
    # To continue that conversation:
    llm -c "Five more and make them more nautical"

All prompts and responses are logged to a SQLite database. You can see the logs using:

    llm logs

This is using the new plugins mechanism I added to LLM last week: https://simonwillison.net/2023/Jul/12/llm/
