We're excited to share that @nvidia and @SapphireVC are joining our Series A, led by @lightspeedvp. Real-time models need infrastructure built for low latency, and that's what we've been building. Thank you to everyone building on Reactor. Fortune has the story, link below.

I've open-sourced an MCP server that lets Claude Code and other agents control TouchDesigner. Given a prompt, it writes shaders, wires operators, checks its own outputs, and iterates towards the goal.
