tl;dr

For GPT, put your OPENAI_API_KEY in a .env file, and then run bash demo.sh or bash demo.sh beta if desired

For embeds, try out https://pinecone.io + set PINECONE_API_KEY and PINECONE_ENV + an index named lc-quickstart

Download + unzip, read through the code, and watch the video / read more on: https://python.langchain.com/docs

Should I care? Business is hard enough; sell me!

Yes. Real-time apps feel like magic for users. But, most magic is explain-able; here's one peek at a minimal solution.

Your engineers tell you it'll take years to build this up, but what if they weren't starting from scratch?

Kafka pushes around data (organized I/O via "topical" streams) allowing messages to "flow" between systems of record.

// mild JS surprises in the Date API
// - getDay() returns 0=Sunday day of week, vs. getDate()'s day of month
// - getMonth() returns 0 for January, which isn't how getDate() works
// - getYear() vs. getFullYear() for year X vs. 1900 + X
//

// JS puts 0=Sunday first, but Zeller considers 0=Saturday (modulate once left)
const days = Object.freeze(['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'])
