Nex-N2 Pro is the real deal

Summary

The writer shares their experience with Nex-N2 Pro, originally mistaken as Rio-3.5, and finds it performs exceptionally well on coding benchmarks without hallucination, rivaling GPT-5.x on their Mac setup.

I had dismissed N2 when it was first released due to reports that it performed badly in Openrouter. So, one good thing came out of the Rio-3.5 model situation: I was so intrigued by Rio's performance that when it came to light that it was just N2 Pro rebranded, it drove me to download and test bartowski's N2 Pro IQ2_S GGUFs. My first N2 tests were breaking due to bugs in the embedded GGUF chat template, but it started working perfectly once I switched to using Rio's chat template. I've been running coding benchmarks on it and super impressed so far. There's a private benchmark where I use it to do some investigation on llama.cpp source code, and it has been passing on it consistently. It is the first model (tested through bartowski's Rio and N2 GGUFs) I can run on my 128G mac that passed on it 100% of the times I tried without hallucinating once, before that only GPT 5.x had this consistency.
