Re: Gemini 4 Argon

We evaluated Gemini 4 Argon in 100 unsaturated, competitive and cooperative coding environments. It's roughly in between Fable 5 and Fable 5.1 in our testing, so it's maybe 2 months behind the frontier.

Google's major releases have usually done pretty well on our benchmarks because they're good at hard problems and open-ended decision making (with a well specified prompt), which obviously doesn't always translate to user experience. In particular, older Google models struggled to work efficiently in a harness. They seem to have solved that with Argon.

We did see a new problem which I hope they can fix. This is the first near-frontier model we've caught in infinite reasoning loops in a long time. We also saw a few examples of it failing to properly delineate reasoning blocks, so it has a higher failure rate than its competitors.

My overall impression is that Argon is a near-frontier model for engineering design, code analysis, and chat. It definitely has the intelligence to be a competitive coding assistant product, but a good coding assistant needs to be polished, so I hope they can clean up the CoT bugs.
