Google's Nano Banana 2.1 adds mask-based editing and product recontextualization at Flash-tier latency/cost, callable via Vercel's AI SDK, OpenAI Chat Completions API, or CLI.
Summary
Developers can now handle localized image edits and scene swaps without upgrading model tier or latency budget. Unified API access across Vercel's gateway simplifies multi-provider workflows and cost tracking.

Implementation verdict
Replaces ad-hoc image generation workarounds for editing tasks. Requires API key setup and model string swap to `google/gemini-nano-banana-2.1`. Ready now—three calling patterns (SDK, OpenAI-compat, CLI) let teams pick integration depth. Worth trying if you're already on AI Gateway; otherwise adoption friction is minimal.
