Reasoning
AI reasoning is how artificial intelligence systems solve problems, think through complex situations, and draw conclusions from available information.
Inference
Inference is a fancy term that just means using an ML model that has already been trained.
Model weights
Model weights are the numbers a model learned during training — an astoundingly unsexy name for the single most important component of an AI model.
AI agent
An AI agent is a model plus a harness — the model decides what to do, and the harness gives it the tools and the loop to actually go do it.
Databricks is apparently worth $100B. What do they even do?
What we should really be asking is “What does Databricks not do?”
ETL
ETL stands for Extract - Transform - Load, and it’s the process of moving data around your internal systems to get it ready for analysis.
Linear Regression
Linear Regression is an old school statistical method for predicting outcomes from a series of numbers.
OpenAI
OpenAI is the most popular provider of generative AI models like GPT-4.
Snowflake
Snowflake sells a powerful cloud data warehouse for analytics and data science teams.

Multi-tenant
Multi-tenant simply means shared with someone else, like having a roommate in an apartment.
ORM
An Object Relational Mapper is software that lets developers interact with their database in their programming language of choice – instead of SQL.
MongoDB

PaaS
Platform as a Service is a category of infrastructure products that makes life easier for developers: instead of managing infrastructure on their own, the vendor takes care of things like installing the right software, managing upgrades, and connecting databases.
Version control
Version control lets you track and manage changes to your code in a more sophisticated way than you’re used to.
New Relic
New Relic is observability software: teams use it to monitor the performance of their apps and infrastructure.
Splunk
Splunk is a tool for storing and searching logs, specifically focused on security.
Tokenization
Tokenization is one of the ways that backends protect sensitive information, like credit cards or social security numbers.
VPN
A Virtual Private Network (VPN) lets you route your internet access through a specialized server that keeps your sensitive information private.
Snyk
Snyk helps developers make sure that the code they're writing is secure.
Okta
Okta is an enterprise-focused identity provider: they take care of managing usernames, passwords, and permissions.
