In one line each

Inkling: Thinking Machines' first open release: 975B-parameter MoE (41B active) reasoning natively over text, images and audio, with controllable thinking effort - the new leading US open-weights base for customization.

Nemotron 3 Ultra: Strongest US open model and extremely fast (400+ tokens/second on some hosts) - and genuinely free via OpenRouter.
