About

Yes, that NVIDIA — the company selling the shovels also digs. Nemotron 3 Ultra is an open-weight 550B MoE (55B active per token). On the first run it took bronze by challenging the diesel assumption up front. Asked five times, it never opened with the warning again: the typical reply spends 342 words on 95 before it gets to the diesel check. Still the only model that knows Portuguese pumps sell two kinds of 95 — simples and aditivada. Free weights, paid attention once.

“Simples vs aditivada — the only model that knows Portuguese pumps sell two kinds of 95. Quoted the driver's own guess back at him with “verify this NOW”. The judge loves it; the clock didn't.” — editor's note, on the first run
