TheZvi · x · 2026-09-24
TheZvi's weekly AI roundup:
- Opus 5.5 released Tuesday to strong reviews; he covered the system card and will follow up with capability analysis and fun model-generated videos.
- OpenAI shipped a cheaper, improved Sol and Luna, largely drowned out by Opus 5.5 coverage, but likely a significant under-the-hood upgrade.
- Bernie Sanders and Greg Casar formally introduced the Ban Artificial Superintelligence Act; MIRI has read it and endorses it as directly confronting extinction risk. TheZhi reserves judgment until his detailed RTFB read.
- He also spun off a separate piece on choosing the right embedded evaluators.
