About Brontosaurus, a voice
Brontosaurus is a web-based generative canvas, where you speak aloud what you want to see, and Bronto builds a widget of it in under a second. There are certainly other labs doing this today, but Thinking Machines takes a unique approach - Sean Goedecke does a great job of breaking down that novelty in his own blog post. Both the technical and philosophical pieces of this approach spoke to me, and they together made me want to build something of the same ethos.
About Stele
Shared memory for AI coding agents. Claude Code, Cursor and Codex read what your project already decided, so context survives between tools and sessions. Only one of these agents knows this was tried last spring and rolled back. KNOW-142 : a captcha on checkout shipped last spring and was reverted after two weeks. The bot traffic is real, though it spikes on release days and is quiet the rest of the time. A gate armed only during a release window would avoid repeating that.
