Model comparison
Compare GPT-Image-2.5 Flare and Nano Banana 2 using the same provider-sourced image generation rubric. No mystery score and no invented benchmark ranking.
Facts checked September 9, 2026
Set your usage. Your estimate updates as you type.
Example output: square 1,024 × 1,024 images. Prices depend on supported resolution and quality; edits and retries can cost extra.
Estimates exclude taxes, tools, cache storage/writes, free allowances and custom discounts. Image estimates cover output only, not prompt or reference-image charges. Quality modes differ by model. Unlisted settings are not treated as free.

| GPT-Image-2.5 FlareOpenAI | OpenAI | $5 text input · $8 image input · $30 image output / 1M tokens |
Quick take
OpenAI's speed-first GPT Image 2.5 model for everyday generation and editing, positioned at GPT Image 2-level image quality with lower latency.
Flare's speed positioning is a provider claim, not a fixed latency guarantee. Run repeated tests with the same prompt, references, dimensions, and quality before moving production traffic.
Google's versatile image workhorse for fast generation, conversational edits, multiple references, grounded imagery, and outputs up to 4K.
There is no free API tier for this model, and grounded generation can add search charges beyond the image price.
Compare the published facts
Values use each provider's own published units and limits. A blank means the provider did not publish a directly comparable value in the sources reviewed.

How to choose
Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.
OpenAI says direct API inputs and outputs are not used for model training by default. Standard abuse-monitoring retention and organization-specific data controls still apply.
Provider and API links
Google says paid Gemini API content is not used to improve its products. Unpaid-service terms differ, so confirm that the project is attached to an active billing account before sending confidential material.
