It's important we now have a recap to the opus 4.8 release where we were threatened with ID verification as "these models become more powerful" and had to pass "verification" to gain full access to the capabilities without having random "cyber" refusals.

Looks like open models being months behind is a thing of the past. Now more like weeks.

Public disclosure of Mythos was April 7 and leaked happened in March, but it's been heavily delayed for well-known reasons.

That said, as the frontier moves, "months old" becomes more and more useful. Opus-tier models are being used to write serious software, so we're going to start seeing open models pick up a lot more usage imo.

Fable 5 is constrained Mythos, which came out before April

Sol came out (public access restrictions that Chinese models don’t have to worry about) just a week ago.

Companies had Claude Mythos access in April. Low chance this is on that level.

That's a more than 2x jump in parameter count. I know it's not a measure of quality by itself, but it will be interesting how it "scales". Bust it looks like they're gonna be competing with the big boys now, pricing also approaches Gpt 5.6 Terra

Open source Fable/Sol challenger! Interesting to do a release product-first.

But, it's not open models.

I hope this means they stop downgrading my fable requests

I'll switch to this for now.

I'm expecting Anthropics reply soon though.

It would be trivial for them to distill Mythos.

AFAIKI Fable = Mythos but with more guardrails

Why do most LLMs insist on a login, even for a free trial?

I entered a question to try it, but as soon as I hit enter it wants my phone number for a login. No thanks.

There's many obvious excuses ...

Are you claiming a necessity ?

Free use without registration -> free to anyone and anything -> easy to abuse at scale, with no way to restrict use.

You can limit it a lot to minimize the abuse. In free entrypoint, set token and context limits to be very small. Limit to 2 prompts per IP or something every X hour. That is already a substantial limit where bypassing might not provide much benefits.

Residential proxies are too prevalent for IP address limits to work effectively.

Is there some public research that how often, for example, people download malware that allows this?

Traditional narrative is that you need tons of traces of actual execution to post-train and get models right. Nobody seems to use Kimi API from Moonshot, I bet everybody is using them on neoclouds/inference providers like Together, Nebius, Fireworks etc. where unlikely they will get traces (in fact, thats the whole promise of these inf providers). How are Kimi models improving so quickly? Is this just distillation (though Sol/Fable just came out so I find it hard to believe)
