Its a completly useless overfitted model trained on 202 epochs of SWE Bench Verified, SWE Bench Pro, Terminal Bench 2.1, DeepSWE.
It gets 100% on SWE Bench Verified, 98.6% on SWE bench Pro, 100% on Terminal Bench 2.1 and 100% on DeepSWE!

Basically, they nerfed their models, then they lower limits without any transparency. Finally, they accused their users of being using their models the wrong way. Gave their free users luna by default and nerfed back to 5-hours limit plus users.
A shared byte model makes the most sense when tokenization inefficiency is already high; for well-tokenized languages, the sequence expansion may still outweigh the benefits unless the SSM is efficient enough to absorb it. But even then, SSM being a real alternative is a huge deal compared to years ago.
1. Knowledge that deeper layers train smoothly.
2. Knowledge that Transformers work but is quadratic on sequence length.
3. Knowledge that SSMs work even better. Numerically unstable sometimes.
4. Speculative-decoding.
5. Open high-quality data.
6. Knowledge that KD works.
It slowly feels like is no longer a bad idea.
Interesting
a little bit skeptic about 1m parameters though
If there is information or artwork that you absolutely do not want copied, archived, scraped, downloaded, or used by others, the safest option is still not to publish it publicly in the first place. That may sound obvious, but the internet was fundamentally designed to move and reproduce information, and there are countless ways to retrieve publicly accessible images:from ordinary browser tools and web scraping to automated or agentic systems.
That does not mean artists should simply accept every possible use of their work. Artists deserve meaningful control, attribution, compensation, and reasonable ways to express how their work may be used. But treating the technology and peopple using it itself as the enemy is unlikely to solve the underlying problem.
There probably isn't a technical solution that can make a publicly visible image simultaneously viewable by everyone and impossible to copy. The realistic goal should therefore be to create better norms, incentives, licensing systems, and tools around how that content is used.
Like, we can imagine a future where every artist gets his/her own credentials and some kind of fingerprint done just like blockchain works. But that requires substantial cooperation among organizations, companies and individuals.
Technology and art are not inherently opposing sides though.
Unlike agents that depend on cloud APIs, local agents give you free inference, low latency, and real privacy.
Removing the per-token cost changes how developers build: agents can now be massively parallelized on local hardware, running background tasks that burn through millions of tokens at no marginal cost!
Good job
Trained on 100B tokens it performs extremely good for its token and size class.
The training took 22 days on one RTX 5070 Ti.

We did not release a Chat version yet because it regressed. Release Later.

Moreover, the implications are that finetuning models already pretrained on structure could outperform ones starting from scratch.
Train a model from scratch on wikipedia with one twist: the tokenizer changes the actual token ids used on every sample fed. If somehow still learns English, you have made an astonishing discovery.
You would have answered the question: Can a model learn human languages from structure alone?
I'm pretty sure you need to check the memory window of that model before training. Check falcon-h1-tiny blogpost to understand what I mean.
Short version: we trained on 200B tokens (~222K:1 tokens-per-parameter). The model peaked at 20B tokens with an INT Index of 4.55, then degraded monotonically over the next 160B to 3.31 โ a 27% regression. Three of four Open SLM benchmarks were worse at the end of training than they were at 10% through.
The useful compute-optimal range for Pico-tier models looks like ~22Kโ30K tokens per parameter. Ratios like 7K:1, 15K:1, and 22K:1 all work fine โ TinyStories and most sub-3M community models sit in this range. Push much further and benchmarks start rotting.
