Gemini 4's model card is a compact 14 pages. Its safety and security report has 217.
This is The Way. It also means we have a lot of new reading material.
I will quickly summarize the model card, then focus on the safety card.
As always, many statements here also apply to other frontier labs.
A lot of this one is probably for diehards (and members of technical staff) only, plus those who find this interesting. Most of you do not need to dig into the cards on this level, and I found most of what we see entirely unsurprising.
The biggest takeaways are:
Argon is clearly much stronger than Gemini Flash 3.8, in essentially all ways.
Argon is not so dangerous as to make us think Singularity Real Soon Now, or otherwise raise the big red flags and alarms.
Argon seems relatively aligned on prosaic metrics. Prompt injection resistance is world class, hallucinations are down and other neat stuff like that. However:
Eval awareness is much higher. It is unclear how much this is impacting things, and we have evidence in both directions (see I Can See Everything).

Anthropic filed its S-1 this week to prepare for its IPO. They still have to fill a lot of the numbers including the share price. That still left a lot to be learned, including how the messaging to investors differs from their other rhetoric, and exactly how their corporate control is structured. Anthropic remains a frustrating company, doing a variety of things that often seem in tension with each other.
The full text is finally here, so we are giving it the full RTFB of model card treatment.
Last week at a small conference, there was talk about a future event referred to as The Hackening. As in, within 6 to 12 months, many predicted that due to advanced AIs and AI agents the internet would become a severely hostile place. Some worried that this could rise to the level of ‘assume any phone connected to the internet is rooted’ and several people urged doing general crisis preparations on a personal level, in case of disruptions in supply lines, power, water or internet.
It was the probably worst day in cybersecurity history. So far. Not only is there a critical flaw in PHP that due to a leak was announced a day before the fix would be available, sending most of the internet scrambling for solutions and likely dooming a lot of long tail websites permanently, there were several other unrelated incidents. The floodgates seem to have been opened. I have a market on whether there will be an even worse day before the end of the year.
