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.

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 Grok Imagine Image 2.0
Missing prompts. Typography and layout, Product photography, Character and detail, Infographic.
No results with the four fixed test prompts are available for this model yet.
Next step. Run the four fixed prompts with this model, archive the first outputs, and evaluate them blind.

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.
