Google's image model gains panoramic 4K and steadier characters, and starts a migration clock. OpenAI agents go native on AWS Bedrock; EU text gets watermarked.

Panoramic 4K and characters that stay on-model
gemini-nano-banana-2.1 is now GA with sharper prompt adherence and multi-turn character consistency, plus ultra-wide ratios (1:4, 4:1, 1:8, 8:1) up to 4K. Repoint your existing image calls at the model string today—no preview flag needed.
Your flash-image calls have an expiry date
The old gemini-3.1-flash-image is deprecated and shuts down October 29. If any app still targets it, you have three weeks to migrate to Nano Banana 2.1 before that image endpoint goes dark.
OpenAI agents, running entirely inside your AWS
Amazon Bedrock Managed Agents powered by OpenAI is in public preview: build GPT-6.1 Sol and GPT-6 Astra UltraFast agents that run in your own AWS account under existing IAM and governance, self-hosted or on AgentCore Runtime. Claude Sonnet 5.5 and Grok 4.7 join Bedrock as frontier options too.
EU text output now watermarked by default
OpenAI has begun auto-watermarking ChatGPT and Codex text for EU users, with an opt-in for global API customers on select models. If you ship AI-written copy into the EU, detectors can now flag it—factor provenance and disclosure into your pipeline.
