GLM 5.3 made this song from scratch.
Much better than what I got from Opus 5.
I asked Opus 5 (effort: high) to make its own representation of a total solar eclipse.
This is what came back. No textures, no models, no photographs, no ephemeris - about 2,300 lines of threejs and nothing else. Sea, sky, clouds, the lunar limb and the corona are all generated
Claude opus 5 averaged 1.70km of travel a day.
Gpt-5 got 1.80, gpt-4o 2.57, and qwen2.5 3b running on my laptop got 4.15. clustering the same places by coordinates got it down to 0.80km. I compared against whichever model won each city, and still didn't lose one. 8 wins, 2
Claude is basically dead to me
Grok 4.6 is ridiculously good I gave it the same black hole simulation test I used with Opus 5 and somehow it came out just as good, arguably better For the kind of work I do, the capability gap between them is starting to feel nonexistent
