They run at 0.25 degree resolution (same as ECMWF AIFS models).

These are available on Weatherbell[1] (which requires a subscription) now except for the HGEFS ensemble model which I'm guessing will probably be added later. AIGFS is on tropical tidbits which should be free for some stuff[5]. I believe some of the research on this is mentioned in these two[2][3] videos from NOAA weather partners site. They also talk about some of the other advances in weather model research.

One of the big benefits of both the single run (AIGFS) and ensemble (AIGEFS) models is the speed and (less) computation time required. Weather modeling is hard and these models should be used as complementary to deterministic models as they all have their own strengths and weaknesses. They run at the same 0.25 degree resolution as the ECMWF AIFS models which were introduced earlier this year and have been successful[4].

Edit: Spring 2025 forecasting experiment results is available here[6].

The browser isn't exposing it to websites. It's simply due to the fact of playing media that it's lowering the minimum timer resolution on Windows. In the past it would also do this when just scrolling among other things if I remember correctly, I'm not sure if it still does this.

Firefox uses a different method that doesn't require lowering the minimum timer resolution.

Either way the global behavior of this is no longer true on modern Windows 10/11 machines (as of Windows 10 2004) as each process must now call timeBeginPeriod if it wants increased timer resolution: https://randomascii.wordpress.com/2020/10/04/windows-timer-r...

Is Zen 5 more like a 4x2 than a true 8 since it has dual decode clusters and one thread on a core can't use more than one?

Chrome distrusted Symantec certs when 70 got pushed to stable (at the end of October)[1]. Digg shows NET::ERR_CERT_SYMANTEC_LEGACY error when I navigate to it. Firefox was supposed to remove the Symantec certs in 63 (also to be released at the end of October) but I guess they pushed it back a version[2].

All major browser coordinated to distrust the certs at the same time.
