I'd be interested to know what was going on with it during the public test as there were numerous reports of it improving considerably at tasks it was asked to do early on in the test compared to later in it.

Two potentials from my pov:

1. Just variance in pass@K. If you prompt any model multiple times you'll see a large variance. N=1, but I find chinese open source models have a higher variance than higher-RL'd models like fable/opus.

2. They legitimately shipped a new RL checkpoint over the 7 days, which I find hard to believe.

I am leaning towards 1.

Mixed signals, here it's performing below even GPT-5.4 Nano: https://livebench.ai/ while here it outperforms Fable by a significant margin: https://oxalpha.com/ but if the latter is true, will people still say it was "distilled" from Fable?

the 2nd website is not official, just something someone slopped together for some reason.

Anyone has a link to a report of its capabilities? I can't find a reliable source.

likely a distilled glm 5.3 that will punch within 20% of that at 2-3x less size. you'll find that capability is typically very jagged on models that are distilled

GLM 5.3 was a great model, so this would be strange to release a regressed model

It's probably GLM 5.3 flash, so weaker but cheaper.

Unfortunately I can't find sources other than this for now but this seems to be legit.

> The company on Wednesday confirmed speculation that the Ox Alpha model is a new iteration of its GLM series and said it will release the weights for it tonight, in response to queries by Bloomberg News.

Seems legit.

It's really hard to know how good it is. So much hype around it.
