Head-to-head comparison
GPT Image 2.5 Sunburst vs. Midjourney V8.1
Compare shared capability tests, arena scores with documented retrieval dates, task-specific image pricing, and verified specifications. Research benchmarks, preference arenas, and our n = 1 samples remain separate.

Specifications and cost
General specifications and task-specific pricing
A model can have one price for generating new images and another for editing. Prices therefore remain tied to the corresponding arena configuration.

Prompt adherence and specialist tests
Shared capability benchmarks
These exact checkpoints have not both completed the fixed Gradually sample protocol. Earlier checkpoints do not substitute for them. No exact shared result from the integrated research benchmarks is available for this pair.
No shared Gradually ranking yet
A score appears only after both exact checkpoints complete all four fixed prompts and the same blind evaluation.
Independent preference tests
Shared arena benchmarks
Artificial Analysis and Arena derive scores from blind comparisons. Raters see outputs for the same prompt and choose the image they prefer. Separate series cover text rendering, photorealism, portraits, art, commercial design, and image editing. Confidence intervals indicate how certain a measured lead is.
No shared arena score in the stored snapshot
The stored benchmark database contains no measurement for GPT Image 2.5 Sunburst and Midjourney V8.1 from the same arena and category. Older model versions are not used as substitutes.
Visual comparison
Sample images
Our images complement preference data, but do not replace it. The prompt, request count, and selection rule match. Provider resolution, quality tier, randomness, and prompt processing remain visible limitations, so this is not a fully controlled laboratory test.
No shared documented run yet
The fixed test suite covers typography, product photography, character details, and an infographic. A prompt appears only after both models have a verifiable first run.
Missing image run for GPT Image 2.5 Sunburst
Missing prompts. Typography and layout, Product photography, Character and detail, Infographic.
This checkpoint was released after the archived test and has no Gradually run yet. GPT Image 2 results remain assigned to GPT Image 2.
Next step. Run the four fixed prompts once with the exact gpt-image-2.5-sunburst API ID, then evaluate the outputs blind.
DocumentationHow to read this comparison
An Elo score is not a verdict on creativity
A higher arena score means this specific configuration was preferred more often in blind comparisons.
Typography, character consistency, local execution, licensing, and price may matter more to your workload than overall visual appeal.
Prices cover 1,000 images at 1,024 × 1,024 pixels using settings documented by Artificial Analysis. Subscriptions and special rates are excluded.
