Google launched Gemini 3 Pro Image (Nano Banana Pro), a next-generation AI image generation and editing model with integrated Google Search grounding, multi-image composition, and fine-grained visual controls, offering pricing at $0.134 per 2K image and $0.24 per 4K image. It features improved text rendering with error rates dropping from 56% to 8% compared to its predecessor, and includes SynthID watermark checks for provenance.

The model is available via Gemini App, API, LM Arena, Hugging Face Spaces, Together AI, and Flow. Meanwhile, OpenAI shared early experiments with GPT-5 accelerating scientific research, including proofs of previously unsolved problems in math, physics, biology, and materials science. "GPT-5 accelerated research tasks in math/physics/biology/materials; in 4, it helped find proofs of previously unsolved problems."
