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.
This should be at the top: they uploaded the wrong model, they fixed it

Brazil does have talent. Mauro Carvalho Chehab is a Linux kernel maintainer. Elixir was created by José Valim, a brazilian. I have also created my own programming language.
What Brazil doesn't have is a history of properly rewarding talent, which often causes it to migrate elsewhere. So it's definitely surprising when any sort of technological development happens in Brazil: it implies someone who stayed managed to get something done, most likely for much less than what that something is actually worth, while also being crushed by extremely high taxes that essentially doubles the cost of computer hardware.

Compared to many countries Brazil doesn't have such high taxes (I'd say that if you work remotely for a company outside of Brazil, you'll probably have much lower taxes compared to almost any other country -- working locally the difference isn't as big, but you have higher taxes in many other places).

> 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.
They merged the base model with another lab’s fine tuned model. The improvements could have come from getting some of the fine tuned weights from the other model.
If they really had a better performing model that they “accidentally” forgot to upload, they could have uploaded the correct file by now.
I only see an edit to the readme (13h ago) and removal of the weights, so the repo is now empty.
I am willing to give them the benefit of the doubt, but we've seen this before: a model gets released that is supposedly state-of-the-art, yet seems to be a an other repackaged model without any training. Reflection 70B was the most similar example, all they now need is an api that rewrites "Claude" to "Rio".

Aurornis 15 hours ago [-]

Enhanced it on a couple benchmarks, supposedly.
The game is to turn knobs until you get a benchmark run that shows an improvement, then ship it. There are a lot of fine tunes and chimera models on HuggingFace that are supposedly better at some specific test, but when you use them for anything else they're usually worse.
This happens with a lot of the models that are modified to remove censorship. They succeed in getting the model to emit previously censored outputs, but the overall output quality decreases.

That is something often claimed by heretics. My experience couldn't diverge more, however. All heretic (and abliterix) models I've tried are worse than the original. It's not immediately obvious if all you do is ask 2-3 questions and marvel at how it didn't refuse, but try using them for real over longer 8k+ contexts and it falls apart real fast.
They're more prone to getting stuck in loops, becoming unresponsive, and hallucinating more (presumably because of the reduced desire to not answer).
I've tried all the popular heretic peddlers, but if you have one that you can vouch for maybe I've simply missed it.
Aurornis 10 hours ago [-]
Abliterarion is a brute force technique that removes or silences parts of the model. It reduces performance because the abliterated elements aren’t perfectly isolated to censorship so other aspects suffer.
Many of the “uncensored” model providers also do some fine tuning on the models. Some of them target better benchmarks or other measures, but outside of the benchmarks and metrics they’re fine tuned for they are generally noticeably worse than the original model.
yowlingcat 9 hours ago [-]
The kind of abliteration you are mentioning is no longer state of the art or the most common form of removing the refusal layer in most models. Your your understanding was up to date about a year and a half ago, but has been out of date since after that.
avadodin 50 minutes ago [-]
What OP is describing wasn't called abliteration at all.
Abliteration whilst a neologism implies a surgical ablation of refusal.
Earlier approaches post–trained the model to refuse less and, much like other kinds of fine–tuning, it degraded performance. They were "uncensored".
Abliteration has seen some improvement to this day but it always was close to equivalent performance to the original when compared to those earlier techniques.
weitendorf 5 hours ago [-]
Unrelated but I’ve been putting off learning about post-abliteration technique and want to use it for an upcoming open source “retraining” project I have on my backlog. I’m not interested in the refusal layers though, more like deep fine tuning but in a way that might let me prune out or consolidate layers, if that makes sense? Do you have any pointers or links to the current SOTA in this area?
I guess I’m looking for a kind of bulk/sticky dropout (which was in fashion way back when I studied DNN in school).

> game is to turn knobs until you get a benchmark run that shows an improvement, then ship it
i.e reinforcement learning against a weak reward function - benchmark is insufficiently complex and is not representative of the real world sufficiently.
The "game", i.e. decision tree can be modeled as a multi-arm bandit problem, to deploy finite resources ( compute) toward exploitation/exploration .
The main issue is each training / fine-tune is very expensive so number of chances at the slot so to speak is pretty limited today.
I don't believe this would work on two LLMs that have different pretraining. Even if it did you would need two LLMs that have exact same internal activation shapes, dimensions, expert counts, token vocabulary, realistically it would never happen outside of finetunes or academic experiments.
hashmap 13 hours ago [-]
not this exact thing, no, because the functional circuits dont appear in the same places across models. but if you find where they are you can do something like branch between some of the middle functional circuits between models and it kinda just works, or even do one after the other. you cant just like swap any two layers cause a bunch of em bend hyperbolic curvature to do hierarchical stuff deep in the poincare ball and the geometries get all bonkers, but before and after they do that things are relatively flat, and the geometries are more or less transferrable up to rigid rotation if they're each trained on large enough data.
oofbey 13 hours ago [-]
Correct. We used to think that because NN optimization is non-convex there are all these local minima. Now we know that once you get past the very early parts of training from random init, the loss surface is fairly smooth, and not really convex, but close enough in a bunch of ways - linear combinations of trained models are pretty much always valid combinations. You can think of fine tunings as deltas on the original model which can be summed together successfully. I think this paper first showed that to me: https://arxiv.org/pdf/1802.10026 which was 8 years ago now.

This is an open weights model based on other open weights models.
The dispute is that they released it with claims about having done some post training that improved the outputs. It was discovered that the model was not post trained like they claimed.
The HF page now says it’s a merge of models, which wasn’t there before. They’re trying to claim they accidentally uploaded the wrong model to HF and that they’ll upload the real one soon.
Basically, they thought they could splice two open weights models together and claim their team had accomplished some amazing post training, but they weren’t smart enough to realize that other researchers would discover that there wasn’t any post training.

The Nex N2 model they merged is based on Qwen 3.5, so you can swap pieces of one into the other. They found a combination of the two that did well on some benchmarks and shipped it.
In the early days of Llama there were a lot of experiments like this. There were even some interesting combinations of models where they stacked layers of different models together or even added more layers with interesting results.
But announcing that you spliced two models together isn't very impressive in 2026, so they announced that they had done their own post training and outdid the big labs. They thought nobody would look close enough to notice.

Nex in turn is also based on qwen so don’t think they’re too far off
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.
https://news.ycombinator.com/item?id=48529544
Anyways SwiTransformer paper looks interesting and doing a post training to optimize for it looks interesting as well.
Rio has a strong engineering talent pool, along with many other major capitals in Brazil
What Brazil doesn't have is a history of properly rewarding talent, which often causes it to migrate elsewhere. So it's definitely surprising when any sort of technological development happens in Brazil: it implies someone who stayed managed to get something done, most likely for much less than what that something is actually worth, while also being crushed by extremely high taxes that essentially doubles the cost of computer hardware.
I always find this funny. Brazilian taxes are nowhere near what I would say “high”. I pay about twice as much out of my compensation as I would pay in Brazil, and that would be as if I did zero tax optimisation back then.
Compared to many countries Brazil doesn't have such high taxes (I'd say that if you work remotely for a company outside of Brazil, you'll probably have much lower taxes compared to almost any other country -- working locally the difference isn't as big, but you have higher taxes in many other places).
What it really lacks is access to capital (which is the real "mojo" of the US compared to the rest of the world).
As a business owner: not so bad if you are a freelancing or just a few business partners providing some type of service, but terrible the moment you start considering employing other people.
Have you seen the public services of countries with lower taxes? Their public hospitals?
> but terrible the moment you start considering employing other people.
Employing people isn't cheap anywhere (except, perhaps, in the US, where labour rights are kind of nonexistent)
They merged the base model with another lab’s fine tuned model. The improvements could have come from getting some of the fine tuned weights from the other model.
If they really had a better performing model that they “accidentally” forgot to upload, they could have uploaded the correct file by now.
https://news.ycombinator.com/item?id=48529544
I am willing to give them the benefit of the doubt, but we've seen this before: a model gets released that is supposedly state-of-the-art, yet seems to be a an other repackaged model without any training. Reflection 70B was the most similar example, all they now need is an api that rewrites "Claude" to "Rio".
https://x.com/tenobrus/status/2066243352211996728/photo/1
I find it amazing how robust the current deep learning models are. A simple linear combination of every weight did not degrade the performance of the model, but enhanced it.
Enhanced it on a couple benchmarks, supposedly.
The game is to turn knobs until you get a benchmark run that shows an improvement, then ship it. There are a lot of fine tunes and chimera models on HuggingFace that are supposedly better at some specific test, but when you use them for anything else they're usually worse.
This happens with a lot of the models that are modified to remove censorship. They succeed in getting the model to emit previously censored outputs, but the overall output quality decreases.
https://web.archive.org/web/20260614082641/https://huggingfa...
And the Nex benchmarks for comparison
https://huggingface.co/nex-agi/Nex-N2-Pro
Rio seems to be about halfway between Qwen 3.5 and Nex, as you'd expect?
They're more prone to getting stuck in loops, becoming unresponsive, and hallucinating more (presumably because of the reduced desire to not answer).
I've tried all the popular heretic peddlers, but if you have one that you can vouch for maybe I've simply missed it.
Many of the “uncensored” model providers also do some fine tuning on the models. Some of them target better benchmarks or other measures, but outside of the benchmarks and metrics they’re fine tuned for they are generally noticeably worse than the original model.
Abliteration whilst a neologism implies a surgical ablation of refusal.
Earlier approaches post–trained the model to refuse less and, much like other kinds of fine–tuning, it degraded performance. They were "uncensored".
Abliteration has seen some improvement to this day but it always was close to equivalent performance to the original when compared to those earlier techniques.
I guess I’m looking for a kind of bulk/sticky dropout (which was in fashion way back when I studied DNN in school).
i.e reinforcement learning against a weak reward function - benchmark is insufficiently complex and is not representative of the real world sufficiently.
The "game", i.e. decision tree can be modeled as a multi-arm bandit problem, to deploy finite resources ( compute) toward exploitation/exploration .
The main issue is each training / fine-tune is very expensive so number of chances at the slot so to speak is pretty limited today.
I don't believe this would work on two LLMs that have different pretraining. Even if it did you would need two LLMs that have exact same internal activation shapes, dimensions, expert counts, token vocabulary, realistically it would never happen outside of finetunes or academic experiments.
It is not understood why it works so well.
[1]: https://arxiv.org/abs/2203.05482
Which could be a signal that your "performance" was so abysmal in the first place that even randomly applied training methods can't make it _worse_.
Then researchers looked at the weights and there is no post training at all.
They are now attributing both models they merged, but their excuse for the lack of post training is to claim they accidentally uploaded the wrong files.
Look up "Reflection 70B" drama.
The dispute is that they released it with claims about having done some post training that improved the outputs. It was discovered that the model was not post trained like they claimed.
The HF page now says it’s a merge of models, which wasn’t there before. They’re trying to claim they accidentally uploaded the wrong model to HF and that they’ll upload the real one soon.
Basically, they thought they could splice two open weights models together and claim their team had accomplished some amazing post training, but they weren’t smart enough to realize that other researchers would discover that there wasn’t any post training.
But it's impossible to form a nuanced opinion when political association has a higher priority than the facts; which, again, don't look flattering for the implementers.
In the early days of Llama there were a lot of experiments like this. There were even some interesting combinations of models where they stacked layers of different models together or even added more layers with interesting results.
But announcing that you spliced two models together isn't very impressive in 2026, so they announced that they had done their own post training and outdid the big labs. They thought nobody would look close enough to notice.
Scroll past the first issue to find it. It’s further down.
(It's not news to anyone who has worked in sales-led businesses that salespeople are prone to believing the claims of other salespeople, I guess).
Lying about your lab's capabilities != Lying about model capability
Exaggerating the capabilities of a new model that you've actually trained in press bulletins can be called marketing. Merging two models and claiming that you trained a new model is plain lazy.
The model card says:
> Post-trained from Qwen 3.5 397B
The model card also says that they use an inference framework based on "SwiReasoning: Switch-Thinking in Latent and Explicit for Pareto-Superior Reasoning LLMs" by Shi et al.:
https://arxiv.org/abs/2510.05069
So the sources seem properly attributed.
They only claim that what they did to "Qwen 3.5 397B" has improved the LLM, including, as expected, with "strong performance in Portuguese".
There (is/was) no attribution to Nex team (they've released a model based on Qwen 3.5 397B as well).
As per OP link Nex claims that what Rio team released (so far) is just linear interpolation of weights between Nex and OG Qwen model. With no attribution to Nex and zero signs of Rio doing any training of their own.

You'll have to let me know when that finally happens, because that ain't now.
Your second one - that's how everything public is paid for. Private individuals pay tax, either through their corporations paying corporation tax or the tax bill on top of their wage bills, which a) drives up prices of the goods and services they offer, or depresses wages, and b) funds all the public sector employees and orgs that don't pay tax (orgs) or don't pay net tax (employees).

Do you understand?
Jokes aren’t that funny when you have to dig into an explanation on the nuance of why the hidden meaning doesn’t match the surface meaning in exact degree and proportions. That turns a joke into a pedantic comment. And paradoxically muddies the point by explaining it.
We aren’t morons. We understand that Picasso is doing something on a different level than someone feeding bulk scraped JPGs of paintings into a python script. You really don’t have to explain.
You should frame this as a reminder to be more charitable in your positions because sometimes you can be wrong. This subthread ended being one of the funniest I've read recently.
But yes, in general, merging refers to techniques that directly blend the weights of different models mathematically. It had a big moment of popularity ~2 years ago, with many so-called "Frankenmodels" popping up on leaderboards.
I tend to think of merging as belonging to the same general umbrella as things like "abliteration", or other techniques that surgically modify the weights of a model without a traditional training/tuning loop. Maxime Labonne is a great person to follow if you're interested in this general area.
Model A: A_1, …, A_n Model B: B_1, …, B_n
C_i = A_i * p + B_i * (1 - p)
In other words, it’s just a linear combination of the other models’ weights, per position.
