AI IMAGE MODEL COMPARISON · 17 MODELS · SAME 6 PROMPTS
AI Image Generator Comparison: GPT Image vs Nano Banana vs Seedream vs Qwen Image
Every text-to-image model on Crazyrouter — GPT Image, Nano Banana, Seedream, Qwen Image, Kling and CogView — answering the same six prompts, side by side. Then run your own prompt against up to four of them with your own API key.
Gallery: one prompt, every model
Images were generated by the maintainers through Crazyrouter with the exact request shown in the preview below (/v1/images/generations, 1024×1024, one image per call) and stored as WebP. Prices are per image from /api/pricing at build time; latency is the wall-clock time of that one call. A model that failed that day may succeed tomorrow and vice versa — it is a sample, not a benchmark.
Run your own prompt
Endpoint, key, prompt, size and models
The key lives only in this page's memory and is sent only to the base URL above. It is never written to browser storage.
Each run sends one real, paid request per model using your own balance. Nothing is retried. Some sizes are rejected by some models with HTTP 400 — that is an upstream limit, not a model failure. Models that answer with a URL instead of image bytes are shown straight from that URL, which usually expires after a while.

One card per model: status, latency, price per image and the generated image

Images returned as base64 are rendered from an in-memory blob URL; URL answers are shown directly. Nothing is uploaded anywhere else.
What this shows
Same prompt, same size, one shot per model — no cherry-picking, no reruns beyond the single retry recorded in gallery.json for 429/5xx errors. It is a quick visual sense of style, text rendering and prompt adherence across providers, not a benchmark or a quality ranking. All gallery requests were sent with response_format: "b64_json" (or output_format: "png" for gpt-image-*, which reject response_format); models that only return URLs were downloaded server-side. Prices come from Crazyrouter's pricing page at build time and may change.
