Elizabeth Interactive CLI with Tool/Function Calling
- OpenAI Chat Completions–compatible client targeting vLLM
- Provides the full Elizabeth MLOps toolkit as callable tools
- Designed for local R&D: no guardrails beyond HTTP auth
Defaults (override via flags or env):
- Base URL: http://localhost:8000/v1
- Model: qwen3-8b-elizabeth (LOCKED)
- API Key: elizabeth-secret-key-2025
Example:
python -m mlops.elizabeth_cli \
--base-url http://localhost:8000/v1 \
--model qwen3-8b-elizabeth \
--thinking chain_of_thought
While running, type your prompt and press Enter. Use commands:
/exit Quit
/clear Clear conversation
/history Show message count
/system ... Set/replace system prompt
/save path Save transcript to a file
This client supports tool/function calling. When the model returns tool_calls,
the CLI executes the function locally, adds the tool result back to the chat,
and continues until the model returns a normal message.
