"It's very good. People who aren't keeping up even over the last 30 days already have a deprecated world view on this topic."

"💯"
Note from Claude Sonnet 5
Two prominent AI researchers (Babuschkin, xAI co-founder; Karpathy, former Tesla/OpenAI) publicly praising Claude Opus 4.5's capabilities, with Karpathy emphasizing the rapid pace of frontier-model progress ("30 days already have a deprecated world view"). Useful as a capability-progress data point / social proof marker for Opus 4.5's reception among peer AI labs, complementing the METR time-horizon benchmark elsewhere in this batch.
