Summary
With Nano Banana 2.1 newly released, Futurepedia runs a broad comparison of the leading image generators: Nano Banana 2.1, ChatGPT Image 2.5, Flux 3 Image and Seedream 5.0 Pro. Each model gets the same prompts across marketing materials, text rendering, character consistency, thumbnails, complex prompts, photorealism and targeted editing, with a winner picked for every test and overall totals at the end.
In the marketing tests, built around a fictional “Future Fuel” energy drink can with small text, Nano Banana 2.1 produces the strongest ad, while Seedream wins a scene with a person where Nano Banana misspells text on the product. For dense infographics, ChatGPT Image 2.5 stands out with essentially error-free text, though it tends to add more text than requested. A very hard prompt, a US map with every national park and arrows to retro posters, defeats every model to some degree, with ChatGPT making the best attempt.
The video also compares Nano Banana 2.1 with Nano Banana Pro and Nano Banana 2, concluding that 2.1 is an incremental improvement. Prompts are provided so viewers can reproduce the tests, and the chapters make it easy to jump to the use case that matters to them.
