Is there a way to obtain a Solar Open 2 API key?

Like everyone else, I’ve been using DS V4 for a while now, and I use a variety of models—including Kimi, MIMO, OpenCode, GLM, and more—through my annual subscription. At first, just looking at the benchmark results, I thought, “Does this even mean anything to me?” But then I ran two problems through Kimi K2.6, DS V4 Flash, Solar Open2, and GPT5.6 Sol—and Solar Open2 and GPT5.6 Sol got them exactly right. This made me wonder if their actual performance in coding might be even better than what the benchmark results suggest.

I’m also active in the community of a U.S.-based startup that provides OpenWeight APIs, and while discussing this,

, but while some people got a 403 error, others were able to access it. I wonder if there are countries where the page doesn’t load. While international service seems unlikely due to language support issues, I thought we might be able to try it out in Korea and English-speaking regions if the performance is decent. If anyone has a trial OpenAI-compatible SolOpen2 API and key, or knows a way to top up and use it, I’d appreciate it if you could let me know.
