Three new models, a price clock, two AI vendor probes

Gemini 4 Argon is half price until November 30, then $4 and $20

Price is the first decision. A team comparing Argon with Opus 5.5 should price both at the later rate, because the introductory rate is half of what Google will charge from December. Google's own table has Argon ahead on the Vals Index and behind Opus 5.5 on Terminal-bench 4.0, so the better model depends on the job. Google chose the benchmarks and ran its own model at its highest thinking setting. For any agent that reads email or web pages, the Gray Swan chart is the most useful part. A 0.7% success rate for attackers is low and still above zero, so keep permissions narrow and test with your own documents.
