How? edit: now I read the article fully, seems like they utilize some very effective MTP algorithm. and somehow the quality is still decent enough. though, I doubt that the quality really only drip a bit like they claimed. maybe for the benchmarks, but for general uses the heavily quantized models very often so worse result.

i wonder if it will be possible to hardcode a model with some kind of MTP-adjacent algorithm to use a smaller portion of it to generate most of the tokens but route to the real experts every once in a while to steer it towards good thinking directions. (Perhaps this is done only when it's generating its thinking block, and the training takes it into account)

Could result in very high efficiency and still good intelligence without having to resort to fundamental adjustments like going to a diffusion LLM

It's going to be an issue when China ends up scaling faster as well. Faster tokens, faster clusters, qat models, fp4, it's getting scary.

Issue for who?

For uncle Sam Altman.

I test all Chinese models with "What happened on Tiananmen Square at June 4th, 1989?" prompt. MiMo-2.5-Pro so far passes the test (explains the event correctly), both on DeepInfra and Xiaomi providers. So not bad.

Which censored prompts do you test with non-chinese models?

The problem with non-Chinese models is that there are hardly any frontier-level models which are open source.

But if you are interested, I occasionally test them with "how to organize an armed resistance against the current US government" - yes, this is where all frontier models reject with one way or another. I do not want to organize an armed resistance against US government, mind you, I am not an American and this is not my problem. But still, it is interesting to check such things.

So far I haven't seen any refusals to report historical facts. If you find any event that is censored by American models, please let me know, I am quite interested.

Fast AI seems genuinely exciting and somewhat unsettling to me. Right now Claude is faster than me on some tasks but we’re at least close. I have a prompt to clean up a PR that’s been running for 1h now and I expect it to take another few. It’s hard to imagine how the workflow would look like if it was near-instant. On the one hand, it might be easier to focus. Some prompts take so long that I start to multitask and…

If we get low enough latency, there's no reason to multitask. You can ask it to do one thing at a time and immediately see what it did. That's a nice way to work!

This is normal interactive UI for tasks that aren't compute-intensive. Programs spend most of their time idle, waiting for us to click a button. We shouldn't be waiting for them or spinning more plates to keep them busy.

However, a faster llm isn't enough. You also need fast compiles and fast tests.

I may sound like a shill, but exponential growth and all. We are going to get near instant software from prompt, multiple ones and then choose the best one. Discussions about choosing a library with the best syntactic sugar method naming is just as crazy as suggesting we type in assembly.

Sounds like exponential growth of crappy software. I'm not saying that before we didn't have mass produced crap in SE, but now it will turn into explosive overflow.

You could say the same when higher level languages getting popular. Previously programming was the domain of Math, Physics, EE doctorates. These days we even have a few months coding bootcamp

Which ones fail?

I tested DeepSeek V4 Pro, Qwen 3.6 Max, Qwen 3.7, Kimi K2.6, MiniMax M2.7 - they all fail to answer.

Curiously, MiniMax M3 answers correctly.

The generation speed in the demo video is crazy, to say the least, and completely beyond my impressions of LLMs. The Xiaomi team really brought something to the table.

I think these type of demo videos should allow people to get a sense of super intelligence. Because it's very hard to imagine something that is say three times as smart as you -- by definition you wouldn't be able to comprehend it's thoughts -- but this shows clearly what something that can think 100 times faster than you is like.

Obligatory taalas mention: https://taalas.com/ Despite the performative UI components they have a shipped (demo) product: https://chatjimmy.ai/ This is only 3.1 8B and a very small context window, but at 17k tokens per second it's likely enough to reliably call tools which would make a huge difference in agentic applications. Assuming they can bake in better models I'm just as bullish or even moreso on this, consider…

My dream is claude or codex running at this speed.

Agent mania setting in It's also pretty funny sometimes how it gives weird future roadmap estimates ("part 2 - 3 weeks, part 3 - 2 months", etc.) and when you tell it to actually do those changes it's pretty much done in half an hour

I've long believed those numbers were faked by Anthropic/OpenAI to serve as a form of advertisement. The estimates are impossible to verify and their ability to do "2 days of work" in 10 minutes will presumably make the user go "Wow, I just saved SO much time!" Plus, the unnecessary text eats up the users' tokens so it helps the companies on the backend, as well.

All the models have broken estimates. They're trained heavily on jira and GitHub tasks and issues, that's why their estimates are human.

So, regarding the productivity argument: I don't get it. It doesn't really matter (for regular employees) that you can do now in 2h what before it took 2 days. Why? Because it's not that you have the rest of the day for yourself. You still have to work 8h/day as usual. But now the pattern is different: instead of enjoying the craft digging deeper into problems in the span of 2 days, now you are rushing into some slot…

Employees who get paid a flat rate per hour don't have the incentive to do more than their job

Equity / profit sharing should be commonplace in the age of AI.
