New comment by rafaquintanilha in "Rio de Janeiro's "homegrown" LLM appears to be a merge of an existing model"

I have no affiliation with them but here's what I think happened:

1. They claim the official model is based on Qwen 397B. It's likely they didn't disclose Nex Pro at all because Nex itself is based on the same base model (not saying they shouldn't).

2. The improvement would come from merging the weights PLUS on-policy distillation. The confusion is that the uploaded model didn't have the distillation at all.

3. It's important to notice they didn't advertise the model besides posting it on Reddit 2 days ago. It became viral organically, over the weekend, and during Brazil's World Cup debut (Brazilians will understand). Of course the mayor of Rio took the opportunity to capitalize over the free coverage, but that wasn't done in conjunction with the researchers.

4. I don't see why they would disclose Qwen 397B as base and mention the SwiReasoning paper but not mention Nex if all they did was to merge both models.

5. In any case, what they are claiming is easily verifiable once (if) they upload the right model.

Doesn't look like it's incompatible. Someone already released a quantization using MTP: https://huggingface.co/foxipanda/Rio-3.5-Open-397B-GGUF

Definitely one of the biggest ROI is to pay for the sync. I regret all years I tried git-based alternatives (it's still useful to have it in git for backup, but not as the main syncing mechanism).

Year is wrong in the article by the way. It says 2025.

Skills are just pointers to context so you don't need to load all of them upfront, it is as simple as that. By the way cursor rules is effectively the same as agents.md.

You can install the Gemini CLI (https://github.com/google-gemini/gemini-cli) but assign a "paid" API key to it (unless you pay for Gemini Ultra).

You realize this is copy to attract more people to the product, right?

They removed the /model option where you can select Opus to plan and Sonnet to execute. But you can still Shift + Tab to cycle between auto-accept and plan mode.

"It is requisite that a man should arrange the things he wishes to remember in a certain order, so that from one he may come to another: for order is a kind of chain for memory" – Thomas Aquinas, Summa Theologiae. Not ironically I found the passage in my Zettelkasten.

When I sat down to write today, I was willing to talk about why blogging is important as a programmer. How surprised I was when realized that the first time I hit publish on an article online was exactly 10 years ago. It just felt right to finish the article and share, not looking for views, but as a testament of what I really meant in the post.

Correct. Moreover, when you are trapped by the government, few things work better than raising international awareness. Even if the companies ultimately comply, that is typically done loud and clear, and eventually snowball until it's unsustainable.

It's funny but also worrying how much Americans underestimate the impact a centralized government can have on people's lives. That probably means that eventually it will happen there.

A centralized – often socialist – government is the _definition_ of monopoly, you can't escape from it without risking jail or worse. No U.S. monopoly, no matter how much you hate it, will get close to this, and you think it does, you are sincerely naive at least.
