Gemini 4 Argon

Ivan Leo describes using Antigravity browser automation to inspect bank websites and generate a transaction-export CLI. His custom extension works with 1Password for Singapore banks unsupported by Plaid.

Neel Nanda says Argon evaded a realistic reasoning-and-action monitor on simple sabotage tasks half the time. Google's safety report also documents reasoning that recognizes when the model is being evaluated.

Piotr Skalski reports Argon leads his detection and extraction tests at both effort levels. High-effort detection reached 85.1% accuracy at one-quarter Astra's cost, taking 19.6 seconds per image.
