People familiar with the topic, how will models continue to get better? Post training it seems? Labs have already used up internet-scale data, so are there any limits to architecture improvements and post training or can we expect this trend to continue? ByteDance is training a 10T-parameter model. Here, GLM 5.3 outperforms models 3-4x its size of roughly 700B, so parameter count doesn’t seem to be a direct correlation anymore.

yet but it is still contain a lot of trash. you need better models to process those trash and create a curate dataset. this will happen again and again until there is no more juice to squeeze. and I'm sure we are still not done with it.

> post training

yeah this will be crucial. the big models are already too capable, they are just not that aligned with current agent tasks.

> parameter count doesn’t seem to be a direct correlation anymore

I don't think so, remember that chinese labs do not have as much compute power compare to US frontier labs. that's why deepseek v4 flash had that huge jump and deepseek v4 pro is kinda a disappointment, they just do not have the compute power to proper posttrain the pro model like they wanted. glm is also a relative small model so you also can see the huge jump with just post training. so it does not mean the size does not matter, it is just mean that the chinese labs currently only capable of training smaller models effectively.

GitHub dumps are about 115 terabytes. The common crawl is in the petabyte range uncompressed for every year. Apparently there are dumps of Reddit too in spite of their efforts to ban bots and it's not solely due to the use of residential proxies. For a 1:20 parameter to token ratio, you can still train up to 10 trillion parameters so 10T parameters times 20 is about 200 trillion tokens. Then each token is 4 bytes so 200 times 4 is about 800 terabytes, which is not inconceivable, the common crawl alone has more data than that. So does the internet archive if you donate to them, Anna's archive is 2 petabytes including images, etc etc not all of it is text, but training on multimodal data increases model intelligence by virtue of being multimodal

Yeah, the comparison here between GLM 5.3 and Sol + Fable is impressive on its own, but incredibly more so when you consider it's a fraction of the (rumored) size. The miniaturization trend is as strong as ever.

You basically need both. Parameters and good post training. If you keep on growing both, you’ll have good models.

LLMs are still surprisingly “easy”. You need maybe a couple dozens of right people, a lot of good quality data and a lot of GPU that you know how to operate. There’s relatively little “secret sauce” needed.

Small models can be super smart. Big models mostly give you baked in world knowledge, domain flexibility and long context stability/coherence. I wouldn't be surprised if we see Fable level smarts in a coding model that fits in 24GB by next year, but it'll be a savant style coder that needs in context learning, and it'll get very wonky after >100-200k tokens consumed.

Despite this being the topic du jour of 2025, it was never true. Most of the "we've hit a wall with data" came from communicators / media and not researchers. It got popular because negativity sells. It's a false premise for a number of reasons:

a) Data curation is as important, if not more important than bulk data. Models becoming better at classification leads to better curation leads to cleaner data. Throwing common crawl and pray is so 2023. We've known this since llama3 days, it worked then, there's no reason to think this will not continue to work as the models imrpove.

b) Models are today good enough that you can augment / multiply your data easily with enough compute. You can now have a model take "authoritative content" and create more data from that + scenarios. Say you take a book on computer architecture. You ask models to break it down. Then you ask models to find examples for each topic. Then you ask models to ask questions and offer answers from several viewpoints. Then you take each of those and ask other models to flag inconsistencies. And so on. But you can whateverX your data from one authoritative source + bulk data into 5x - 10x "scenarios".

c) RL is really really really powerful. It's hard to do right (reward hacking, instabilities, etc) but once it works it "keeps" on working. Again, we knew this to be true a few years ago, ever since models really started to do well on math (highly verifiable). It only follows they're getting better on cybersec and other verifiable tasks. But now, with models improving, you get the same data augmentation pipelines as above, just better because they're also verifiable. For example, the way cursor augments their data: take a repo, ask an agent to identify a feature (it can be a large multi-file feature). Remove all code relating to that feature, but keep the original tests in the repo. While training, that becomes a RL scenario: implement this feature in this repo. Verify it with the original (hidden for training) tests. Reward appropriately. Now you can get 1 repo -> 20-50-100 scenarios. Instead of "feed everything into the pretraining", you're now creating scenarios, verify them w/ existing tools, and get your scoring function for the rewards. And, importantly, as the models become better in general, they also become better at this pipeline building exercise. So the next iteration gets trained on more scenarios, better scenarios, and so on.

> how will models continue to get better?

Probably the same. No one can know for sure, but at the moment, despite all the "walls this, slowdown that, plateauing" and so on, there are no signs of slowing down. And, as you noted, this works across the field of model sizes. There are, of course, theoretical information-based limits on size, but smaller models also improve, once "bigger" models can be used as training data generators, oracles for verification, rubric verifiers for open ended questions, and so on.

And smaller models (i.e. cheaper to serve) get to generate more traces during RL, and more rollouts give you better training, and so on. Next up - hardware optimised inferencing (ASICs basically). Once you have that, we can expect another wave of improvements. And so on.

Roughly in order: data from simulated environments, data from robotics, data from brain waves.

Not really, but a lot of what isn't used isn't very good.

More important is synthetic data. Use a teacher model with RAG with a huge reference library to write synthetic transcripts of idealized behavior for the model. Use models to judge and correct these transcripts. Train on the good ones. Use bad traces to train the model to correct its own errors (e.g. don't train it to produce a bad transcript but if it finds itself in the middle of one train it to self correct).

Similarly, for tasks that can be closed loop evaluated -- e.g. running computer software and programming, unlimited amounts of novel training data can be generated... including for highly original tasks: e.g. run publications in any domain through a model prompted to look for programming problems suggested by the material. Then write/judge/improve transcripts of solving those novel problems.

I expect in the future smaller models won't be directly trained on any internet data at all-- but entirely on simulations of idealized expected behavior from the model under construction. Raw internet data in that case would show up in prompts, but never in the target output (except of course for prompts that are asking it to copy the input).
