Episode Details

Not only is Opus 5.5 out, pushing the frontier of AI, it also tells us much about what is going on inside the labs, as they both warn about, and promise, Recursive Self Improvement, aka automated AI research. I cover the model (digging into its 230 page paper), labs’ mixed record on promises, why following what is happening in AI is getting almost impossible, and just so much more that even a summary in this description would get too long.
