Ideogram·medium signal

Released June 3, Ideogram 4.0 is the company's first downloadable foundation model: 9.3B params, native 2K output, structured JSON prompting, and strong text rendering, topping open-weight rankings on DesignArena. Licensing is split — inference code is Apache 2.0 but weights fall under a non-commercial agreement requiring a separate paid license for production use. The JSON-layout control is a real workflow shift for design-tool builders.
