So we now have a pretty good picture of the state of the frontier AI model makers. US closed source models continue to lead. Google, OpenAI, and Anthropic stand well ahead of the pack, and may have signs of recursive self-improvement. xAI has fallen from frontier status for now

Anthropic’s Glasswing Promotion: A Flawed Zero-Knowledge Proof
By
–
A zero-knowledge proof is a way to convince you I know something without actually telling you what I know. Anthropic’s promotion of Glasswing is like a zero-knowledge proof without the proof part: you don’t gain any knowledge, and you may not be convinced, but you have a sense

Meta’s solid frontier model re-entry, not matching benchmark vibe
By
–
Anyhow, its not bad. Just not the vibe level that the benchmarks might indicate. And, for a first re-entry into the frontier model space, given the engineering efficiencies they achieved, it feels like a solid attempt. I am sure we will see better from Meta in the future.

Meta’s Muse Spark Thinking lags behind Big Three, seems weird
By

After playing with it a bit, Meta's Muse Spark Thinking is fine so far, but really doesn't match the current Big Three models. It also is a bit… weird. Like some strange language & tone, a little loose with facts, etc.

And here is how it does on the neo-gothic shader test. https://t.co/hxsUTOVTO3 pic.twitter.com/aDlcslfdSuAfter playing with it a bit, Meta's Muse Spark Thinking is fine so far, but really doesn't match the current Big Three models.
