Doesn’t the widely accepted Bitter Lesson say the exact opposite about specialized models vs generalized?

Bitter Lesson is about exploration and learning from experience. So RL (Sutton's own field) and meta learning. Specialized models are fine from Bitter Lesson standpoint if the specialization mixture is meta learned / searched / dynamically learned&routed.

Is anyone doing any form of diffusion language models that are actually practical to run today on the actual machine under my desk? There's loads of more "traditional" .gguf options (well, quants) that are practical even on shockingly weak hardware, and I've been seeing things that give me hope that diffusion is the next step forward, but so far it's all been early research prototypes.

Because diffusion models have a substantially different refining process, most current software isn't built to support it. So I've also been struggling to find a way to play with these models on my machine. I might see if I can cook something up myself before someone else does...

I wish there would be more of this research to speed things up rather than building ever larger models

Notice how all the major AI companies (at least the ones that don't do open releases) stopped telling us how many parameters their models have. Parameter count was used as a measure for how great the proprietary models were until GPT3, then it suddenly stopped. And how inference prices have come down a lot, despite increasing pressure to make money. Opus 4.6 is $25/MTok, Opus 4.1 was $75/MTok, the same as Opus 4 and…

You're hitting on something really important that barely gets discussed. For instance, notice how opus 4.5's speed essentially doubled, bringing it right in line with the speed of sonnet 4.5? (sonnet 4.6 got a speed bump too, though closer to 25%).

It was the very first thing I noticed: it looks suspiciously like they just rebranded sonnet as opus and raised the price.

I don't know why more people aren't talking about this. Even on X, where the owner directly competes in this market, it's rarely brought up. I strongly suspect there is a sort of tacit collusion between competitors in this space. They all share a strong motivation to kill any deep discussion of token economics, even about each other because transparency only arms the customers. By keeping the underlying mechanics nebulous, they can all justify higher prices. Just look at the subscription tiers: every single major player has settled on the exact same pricing model, a $20 floor and a $200 cap, no exceptions.

Nothing to do with each other. This is a general optimization. Taalas' is an ASIC that runs a tiny 8B model on SRAM. But I wonder how Taalas' product can scale. Making a custom chip for one single tiny model is different than running any model trillions in size for a billion users. Roughly, 53B transistors for every 8B params. For a 2T param model, you'd need 13 trillion transistor assuming scale is linear. One chip…

The 2.5kW figure is for a server running 10 HC1 chips: > The first generation HC1 chip is implemented in the 6 nanometer N6 process from TSMC. ... Each HC1 chip has 53 billion transistors on the package, most of it very likely for ROM and SRAM memory. The HC1 card burns about 200 watts, says Bajic, and a two-socket X86 server with ten HC1 cards in it runs 2,500 watts. https://www.nextplatform.com/2026/02/19/taalas-et…

I’m confused then. They need 10 of these to run an 8B model?

It kind of makes sense, at least a year or so ago, I know $20.00 unlimited plans were costing these companies ~$250.00 averaged out, they're still lighting money on fire with $200.00 but probably not nearly as bad, however, I'm not sure if costs have gone up with changes in models, seems like the agentic tooling is more expensive for them (hence why they're pushing anyone they can to pay per token).

I worked on it for a more specialized task (query rewriting). It’s blazing fast. A lot of inference code is set up for autoregressive decoding now. Diffusion is less mature. Not sure if Ollama or llama cpp support it.

Did you publish anything you could link wrt. query rewriting?

It's the same thing. Quantize your parameters? "Bigger" model runs faster. MOE base model distillation? "Bigger" model runs as smaller model.

There is no gain for anyone anywhere by reducing parameter count overall if that's what you mean. That sounds more like you don't like transformer models than a real performance desire

These AI companies are all in the same boat. At current operating costs and profit margins they can't hope to pay back the investment, so they have to pull tricks like rebranding models and downgrading offerings silently. There's no oversight of this industry. The consumer protection dept in the US was literally shut down by the administration, and even if they had not been, this technology is too opaque for anyone to really be able to tell if today they're giving you a lower model than what you paid for yesterday.

I'm convinced they're all doing everything they can in the background to cut costs and increase profits.

I can't prove that Gemini 3 is dumber than when it came out because of the non deterministic nature of this technology, but it sure feels like it.

Similar trend in open text-to-image models: Flux.1 was 12B but now we have 6B models with much better quality. Qwen Image goes from 20B to 7B while merging the edit line and improving quality. Now that the cost of spot H200s at 140GB came down to A100 levels, you can finally try larger scale finetuning/distillation/rl with these models. Very promising direction for open tools and models if the trend continues.
