We compared generations from September 9, 2026, during the period when all three models were in use. This 57-generation sample includes images beyond the 16 visual challenges. We excluded failed and unfinished generations.

We used Azure for GPT Image 2 and OpenAI for Flare and Sunburst. The measurements include provider response time and app processing. Your wait will vary with the request and service conditions.

How we tested

We compared GPT Image 2, Flare and Sunburst across the same 16 challenges as our Nano Banana 2 comparison, for 48 images in total.

Read the method and limitations

We generated the images in HummingBytes on September 8–9, 2026. For each challenge, we used the same English prompt, aspect ratio and reference files with all three models. We kept the reference order unchanged and used High quality with Auto background.

We show one result per model for each challenge. We kept the original images without retouching or cropping.

Square outputs are 1024 × 1024, portrait outputs are 1152 × 1536, and 4:3 outputs are 1536 × 1152, all using the 1K preset. The website hero uses the 2K preset at 2560 × 1440 because 16:9 is unavailable at 1K. Each challenge has matching dimensions across all three workflows.

We assessed composition, visible text, instruction following and reference preservation. These category-level judgments draw on one image per model per challenge, so they indicate strengths to test with your own prompts. We ran overlapping requests. The speed section reports recorded waiting times in HummingBytes, including provider overhead.

Background-only bag edit

What this test checks

Move the camera sling to a rainy sidewalk outside a coffee shop while preserving its canvas, seams, hardware, strap and camera angle.

Verdict

GPT Image 2.5 Flare

What we observed

Flare wins on product lighting. Its brighter blue-hour background and warm reflections make the bag easier to see than in GPT Image 2’s darker scene.

Tradeoff

Neither output is an exact cutout of the reference. Compare the top handle, fabric creases and side proportions before using either as a faithful catalog edit.

Compare GPT Image 2 with

Physical sign text replacement

What this test checks

Change ONLY to ALWAYS while preserving GOOD, VIBES, the physical letters, sign framing and street scene.

Verdict

Both replace the word correctly

What we observed

Both show GOOD VIBES ALWAYS and retain the board, pavement and blurred background. Their letter placement and framing are very similar.

Tradeoff

Both render a wider 3:4 view than the original 2:3 reference. The wording succeeds, but the result is not a pixel-preserving edit.
