A question about your own business data still means a ticket, a queue, and a week of waiting. Cube hands that workflow to AI agents: they model the data, explore it, and build the reports — your team guides and approves — so week-long analysis comes back in minutes. And because every agent works from one governed set of metric definitions, the answers come back right. 400+ companies run on Cube, including Brex, Wix, Patagonia, and Webflow.

In this article, you will learn how to build a complete agentic workflow in Python with LangGraph, from a single model call to a tool-using agent with persistent conversation memory. Most AI agent setups handle the single-turn case well: take a question, call a model, and return an answer. The harder problems appear soon after that.

Grok Voice Think Fast 2.0 starts speaking 0.70 seconds into a call, against 1.21 seconds for OpenAI's GPT-Realtime-2.1.The model resolved 56.5% of test support calls where OpenAI's flagship managed 45.7%, though OpenAI leads narrowly on conversational flow. The grok-voice-latest tag switches over automatically on August 5, priced at $0.08 per minute of audio.

Prompts are dependencies. Changing them can shift downstream behavior with no warning, no failing build, and no obvious signal in the request pipeline. Treat prompts exactly like any other artifact that can change production behavior. Test them, give them a gate, and default that gate to blocking until proven otherwise.

Most people try to learn AI by jumping between random YouTube videos and tutorials. Microsoft released a complete free AI curriculum on GitHub that takes you from the fundamentals all the way to neural networks and modern LLMs, with hands-on labs, quizzes, and real projects. If you've been looking for a structured way to actually understand AI, this is one of the best places to start.
An entire ad agency in the palm of your hand.
Your next campaign needs a dozen fresh ad variations by Friday. Your agency quotes two weeks and a five-figure invoice. Your in-house designers are already buried under this quarter's requests.
Hightouch Ad Studio fixes that. It reads your brand guidelines, your best-performing creative, and your product catalog, then generates on-brand ads your team can ship the same afternoon. You review and approve every asset before it goes live, so quality holds.
Growth teams use it to build variations for every audience, test more of them, and stop rationing creative because production got expensive. The work that once needed a full agency retainer now runs inside your own workflow, at your pace and under your direction.
You direct the work while Ad Studio handles production, and your designers get their week back.
