From April 2026. It's not immediately obvious to me whether they did release the information promised, but it looks like somebody from Meta reproduced the effort using Claude Opus 4.6 and 4.7: https://github.com/tanfer-meta/vercore (edited to add: claiming substantially better performance than Vercore)
It works be interesting to see how Opus 5.5 does with the same task.
