AI Daily Brief — 26 February 2026

Thursday delivers a top-tier image launch and the Anthropic-Pentagon showdown. Google ships Nano Banana 2 — also branded Gemini 3.1 Flash Image — at Pro quality but Flash speed. It supports 512px → 4K, 14 aspect ratios, up to 14 reference images, real-time web-grounded generation via Google Search, and character consistency across up to 5 subjects and 14 objects. Pricing: $60 per million output tokens — about $0.067 for a 1K/2K image. Nano Banana 2 takes #1 on Artificial Analysis’s Image Arena at launch. Dario Amodei publicly rejects the Pentagon’s request: “These threats do not change our position: we cannot in good conscience accede to their request.”
