Part 1 was the why. Part 2 was the where. Part 3 is the how. Alex and Maya walk through the LLM Command Center, a single console for the entire domain-specific LLM lifecycle.

Topics covered:

- Recap of the series: why domain-specific LLMs (the Pluribus framing) and why hospitality

- The Command Center: chat compare, pipeline, observe, data, quality, lineage, HP sweep, train, register, deploy, evaluate

- Honest results: fine-tuned Qwen3 95.1, frontier Claude 94.1, base Qwen3 83.9 (MVP run, 10 of 47+ scenarios)

- Why data is the critical piece, and the curation behind a 5,000+ record hospitality dataset

The Portal is still under development. The complete cycle is open source as a Jupyter notebook lab on AWS Samples: https://github.com/aws-samples/sample-industryllm-mlops

Next episode: Abhijeet and Bharat go behind the scenes on building the platform and curating the data.
