NVIDIA-Nemotron-3-Ultra-550B-A55B was released in June 4th 2026 and I think it was the largest open US model until thinking machines' Inkling (975B) was released a couple of weeks ago.

Yeah, besides that, the only big other open source US model that was worth looking at was Inkling (975B params), Jul 15, 2026.
