So which shovels companies are the ones to watch for burnt in silicon models ?

$CBRS - Cerebras Systems There is other in the space, Groq and Sambanova are both private companies attempting to develop their own technology.

Cerebras and AMD collabrated on some Helios system stuff.

Deepseek Flash is still much cheaper: - lower input/output token pricing - the cached token price is $0.0028/Million tokens, which is like 50-90% of tokens

DeepSeek Flash is a much worse model. Even DeepSeek Pro is much worse.

Oh how the turntables literally next day.

Those finanicals show OpenAI makes good money on inference.

You might need to reread that mate.

> Revenue: $3.7 billion

That's how standard accounting rules for public companies would measure it.

Model segmentation & distillation like this that asks the consumers to pick exactly which version of the algorithm will solve their problem is evidence for lack of intelligence instead of its presence.

You really really don’t need to pick. Just use Sol on high. That’s my daily driver and I don’t touch the model picker at all. Now, if cost is your concern, then that’s a problem in all of computing. Hence why I’m sending you short plain text messages using an iPhone with a many-core CPU and gigabytes of RAM.

That's great. I'm sure you get a lot of good value out of it but eventually OpenAI will have to become profitable & they might curtail consumer resources.

You're right of course, LLMs provide a partial, unsound oracle. The "halting problem is unsolvable" argument relies on the oracle not being able to output "not sure". But adding that option admits trivial oracles, like ones which output "not sure" for everything, so some are better than others. The "real world" use most people have for halting oracles is as part of software safety, where if the checker outputs "not s…

Even if we had an answer to the halting problem, from a practical point of view, it's solving the wrong problem anyway. There's no point in distinguishing a function that would run forever from one that would exit after a century. They are both too slow. Knowing that functions terminate is important for proof languages like Lean, where you often want to prove things without running the code at all. You're proving tha…

It's an engineering vs science question, and we've solved the practical but not the theoretical. LLMs being non-deterministic is another one of those things.

I think this is an unsolved problem. The most interesting thing I saw here is the Recursive Language Models paper. https://arxiv.org/abs/2512.24601 There's also a great write up here by the author: https://alexzhang13.github.io/blog/2025/rlm/

I used this architecture for a while. The problem I have with it is that starting from one agent and fanning out keeps things mostly aligned with that single reasoning trajectory, even as you get a few layers into the stack. Every recursive invocation is a product of the caller's current state. Diversity doesn't really occur on its own unless the environment (tool calling) is complex/chaotic. RLM might be more useful…

Yeah, a lot of people have reported significant gains from "model fusion" lately, which I think the literature just calls ensembles. You just ask a bunch of models to do a thing and then you combine the results.

Research tasks benefit the most from this. Because such work benefits from having a large number of agents working on a problem in parallel (i.e. crawling the web), and the model size becomes less important past a certain minimum.

I don't know about other categories of work, like programming. I imagine looking for bugs or security issues would benefit from it.

If you optimize program A and manage to wring out a 1% improvement, and I optimize program B and improve performance by 20%, you can see the problem with trying to infer anything from those two numbers. Edit: searching for the story now, further bolstering the point is that was 1% in training time [1], and the openAI claim is 20% in end to end inference cost . This is a bad comparison.

No it doesn't. You have no idea how optimised the underlying kernels already were. If a kernel was already optimal, it doesn't matter if you bring a brain the size of a planet, you're not going improve it.

> Second, 20% gains in inference today gives better end results (i.e. lower overall cost) than 1% in training 2 years ago

Your claim (at least in implication) was some kind of trend here. It doesn't matter which one was better to optimise because it "gives better end results" if you're trying to make a trend line out of two unrelated things.

I'm looking for more efficient ways to pack items into packaging. You're looking for more efficient ways to dispatch workers. I report how much faster I can get a shipping container loaded. You report how much less it costs to to get powerlines fixed during a storm.

It's a bad comparison.
