 **TL;DR:** Starting today, **September 30, 2025**, we bill **per second** at the **exact same rate as before**: **\$0.50 per minute**, billed per second, which is **\$1/120 per second** (about $0.008333). We **round Half-Up to the nearest cent per call**[^half-up-def] after the calculation, we never round your time. Two-week notice: starting **October 14, 2025**, calls under 10 seconds will be billed per second as well. Included credit dollars are unchanged, only the unit changes to **seconds**.

 Mechanical CAD is in the dark ages. Mechanical CAD engines are decades old, which is great for encompassing lots of knowledge but makes them incredibly slow since they were originally developed for the computers of that time and cannot take advantage of modern hardware. CAD programs are hard to automate into pipelines like software engineers are used to. When you change your models, you should get instant analysis feedback on your new models… interference checks, structural failures, you name it.

 Today we are introducing our [Text-to-CAD add-on for Blender](https://github.com/KittyCAD/text-to-cad-blender-addon). In the world of digital design and 3D modeling, the bridge between conceptualization and realization is crucial. Powered by [Zoo.dev](https://zoo.dev/)'s [ML-ephant Machine Learning API](https://zoo.dev/docs/developer-tools/api/ml), this add-on allows users to generate CAD models directly from text descriptions.

 You know what's the absolute worst? Surprises. Especially when they're tiny cubes multiplying silently in your CAD models, like some evil nano-scale gremlins. But hey, that's what we inadvertently _almost_ allowed in our KCL library design. Enter the "CNC Injection Vulnerability"—a term we[^1] proudly coined after discovering the absolute horror of what might happen if we didn't design our library system correctly.

 On Monday, January 15th, we will be turning on billing for [Text-to-CAD](https://zoo.dev/text-to-cad). Let’s go over a bit about what this means. Our APIs and tools have pay-as-you-go pricing. You get 20 free minutes of API access per month, followed by a cost of $0.50 per minute for additional usage.[^2025-billing-update]

 Hi, Zoo users! This month we had KittyCAMP, our annual all-hands in Los Angeles. All our employees around the world met each other in person and we celebrated our launch of Zoo Design Studio 1.0 together. This meant we only had 3 weeks of coding, but we got a LOT done this month! Here are some of the biggest features we've added to our CAD suite this month.
