Wait isn't Fable like 2x more expensive if we compare under 272k tokens

Peak under your skin a bit. Something weird is going on. I think we are bots/robots(sic)

I think it's pretty obvious that, in that world, the AIs will simply be tasked with making the compilers faster. It's already happening with their own stack, after all.

Speed is independent of quality. LLMs are currently completely incapable of producing a good compiler. I'm not convinced that's going to change (and if it does change, we're all unemployed).

Look at the employed person

Fast mode is already 1.5 times faster and 2x more expensive in the Codex subscription plan. If this thing is 14 times faster, then I can imagine running out of my quota in one session.

There is zero chance this will be offered to subscription users.

I'm guessing a new $1000/month tier

ChatJimmy is a much smaller model and, AFAIK, has no reasoning capability. Absolutely insane raw speed, like a supercar, while Sol is more like a freight truck.

The knowledge of ChatJimmy is terrible. Even Qwen on my iPhone is better.

well, yeah, it's based on a 2+ year old tiny model. It's very much an alpha proof of concept that they can perma-bake an LLM into silicon.

I've been waiting so long for something amazing to come out of the OpenAI and Cerebras collaboration. > In our evaluations, GPT-5.6 Sol on Ultrafast mode answered all 2,500 HLE questions in 11 hours and 11 minutes. Claude Fable 5 needed 78 hours and 27 minutes, more than three days of continuous compute, to arrive at the same conclusions. In other words, Ultrafast worked through the frontier of human knowledge in a s…

Answering 2,500 independent questions is an embarrassingly parallel workload, all it needs is scale out. It would be more meaningful to know how much time was required for a single complete answer to a difficult HLE question.

I believe the assumption of the benchmark creators is that it's meant to measure the sequential speed that a single instance of the LLM and piece of hardware can get through all the tasks from start to finish, like running a race. As a rudimentary comparison, sort of like doing prime number calculations as a benchmark of the CPUs in one bare metal server. Of course you'd get a speedup in total number of primes searched if you ran the same software of GIMPS on 8 servers with the same hardware in parallel rather than 1 server.

Of course if you took all the individual questions in humanity's last exam and fed them in parallel into separate queries to Claude that land on separate hardware instances of the claude model you'd get a speed up. Because each question is independent and not related to knowledge/calculations that are performed in any other question it is indeed very open to speed up by breaking it into separately dispatched parallel tasks.

Now I can blast through my weekly 20x pro codex credit in like an hour, great!

The amount of usage you receive on Codex these days is dismal compared to what it was a few months ago, FYI.

And they charge more for going faster.

As a Codex customer, I am not impressed with their shenanigans over the past few months and I have resolved to master the art of Pi Coding Harness creation and loving it.

Thanks for all the fish, Sam!

What kind of bot would say `less guardrails` instead of `fewer guardrails`? I guess someone could instruct an LLM to deliberately make mistakes, but isn't that too paranoid?

We’re reaching transvestigation levels of people trying to spot AI text everywhere they look

With this level of intelligence offered at this level of speed, new real-time applications become possible, such as providing expert advice during a phone call or court hearing. Current SOTA models are too slow in many cases to provide the kind of insights that we expect to receive from an intelligent human colleague, such as a sales coach or lawyer handing us a note or writing a Slack message during a difficult call. For these real-time applications, even a 10x increase in per-token cost would often be tolerable.

Right now, the "economic model" of AI is "who has the best model", or really weights.

That'll go away eventually, just like operating systems eventually became free.

Instead, it's going to come down to selling inference hardware. We'll likely see the "apple" model where a custom OS runs on their hardware, but we'll probably also see more things like Cerebras become commodity hardware instead of kilowatt-class datacenter only hardware.
