Arize Phoenix demonstrates using PXI to run an experiment comparing system prompt vs schema-aware prompt with a programmatic code evaluator, avoiding the need for an LLM judge.
PXI (Phoenix Intelligence), the AI agent previously only available in-browser, is now available as an interactive chat in your terminal via the CLI package @arizeai/phoenix-cli.
Arize Phoenix's built-in agent PXI now supports slash commands and skills, allowing users to invoke custom workflows directly from chat.
