gemini-2.5-flash-image is the original stable Nano Banana model. On YingTu, it is the lowest-priced option in the family and keeps the established Gemini native request shape for text-to-image and image editing. Google positions the upstream model for high-volume creation, conversational editing, and low-latency visual workflows. Its stable model ID replaced the deprecated gemini-2.5-flash-image-preview ID. See Google’s current model page.
Use the exact stable ID in the URL. Do not use the old preview ID or send imageSize; YingTu treats this model as an approximately 1K output tier.

What YingTu verified

A September 2, 2026 live run completed synchronous generation, asynchronous generation, and inline image editing. The tested 1:1 outputs were 1024 × 1024 PNG files. One synchronous response returned a text part before the image, confirming that clients must scan every response part.

This is not a quality benchmark. The recommendation combines current upstream positioning, YingTu price, and verified API behavior; evaluate visual quality with your own prompts and source images.
