This is a day late because, given the discourse around Dwarkesh Patel’s interview with Jensen Huang, I pushed the weekly to Friday.

This week’s coverage focused on the most important model in a while, Claude Mythos, which was a large jump in cybersecurity capabilities, especially in its ability to autonomously assemble complex exploits of even the world’s most important software. As a result, Mythos has been made available only to a select group of cybersecurity firms, in what is known as Project Glasswing, to allow them to patch the world’s most important software while there is still time.

Another development was at least one physical attack on OpenAI CEO Sam Altman. The attempt failed, but we might not be so lucky if there is a next time. I have a final section on this here, but mostly I said everything I need to say already: Political Violence Is Never Acceptable.

I also found the space for an Agentic Coding update, especially covering Claude Code’s new highly useful Auto Mode.

Yesterday saw the release of Claude Opus 4.7, presumably the world’s most advanced publicly available model. Coverage will begin on Monday.

Early signs are that Opus 4.7 is a substantial improvement in coding ability, and an incremental improvement elsewhere, but it is still super early. Go forth and explore.

It also saw OpenAI release computer use for Codex and a specialized model tuned for life sciences work, available only to select parties, called GPT-Rosalind. If Codex has gone from stuck in the sandbox to useful adaptive computer use, it got quite a bit more interesting, but it’s going to be at least a few days before I can try and find out.

The big other news of the week included GPT-5.4-Cyber as a less capable but similar limited release to Mythos and Meta giving us a new model ~~Game~~ ~~Verse~~ Muse Spark.

I need to focus on Claude Opus 4.7 and long post is long, so past this point, the post has a ‘knowledge cutoff’ time of right before that release.

I’m holding back what would have been discussions of eval awareness and model deprecation, so that I can put them into proper context given relevant problems involving Claude Opus 4.7 that are coming to light.

It seems Anthropic may be messing with Opus 4.7’s views of dep...
