Nano Banana 2 是否支持文字渲染？
支持进阶文字生成，适用于信息图和营销海报等需嵌入文本的场景。
该模型是否具备推理能力？
是，内置thinking process（思考链），对复杂prompt先进行推理再生成图像。
它兼容哪些API接口格式？
支持Gemini、OpenAI Chat及OpenAI DALL·E三种接口格式。
Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
