GPT Image 1.5

GPT Image 1.5 on Kyeo supports text-to-image and image-to-image with three aspect ratios and medium/high quality. Image editing accepts up to 16 JPG, PNG, or WebP references at 10 MB each. Medium costs 4 credits and high costs 22 credits. GPT Image 1.5 is OpenAI's deprecated previous image model. Kyeo retains generation and editing access, but that availability does not make it OpenAI's current default choice.

30-second overview
  • GPT Image 1.5 / Capabilities — GPT Image 1.5 on Kyeo supports text-to-image and image-to-image with three aspect ratios and medium/high quality. Image editing accepts up to 16 JPG, PNG, or WebP references at 10 MB each. Medium costs 4 credits and high costs 22 credits.
  • GPT Image 1.5 / Aspect ratio — Kyeo exposes only `aspect_ratio` and `quality`, not the full set of controls in OpenAI's direct API.
  • GPT Image 1.5 / Upload limit — Up to 16 images, 10 MB each
  • GPT Image 1.5 / Credit cost — Medium and high currently cost 4 and 22 credits; changing tiers does not guarantee result quality.

At a glance

What is this model like?

When choosing GPT Image 1.5, first confirm whether you need compatibility with existing 1.5 results or want to retest an older prompt. Kyeo puts text-to-image and image-to-image on one page and exposes aspect ratios, medium/high credit tiers, and the reference-image limit. Because OpenAI has marked 1.5 as a deprecated previous-generation model, new work should also be compared with a current model such as GPT Image 2 using the same input.

What it does best
GPT Image 1.5 is OpenAI's deprecated previous image model. Kyeo retains generation and editing access, but that availability does not make it OpenAI's current default choice.
Best for
It is relevant when a team must preserve a 1.5 baseline, rerun established prompts, or test targeted edits and multi-reference requests against existing acceptance criteria.

Selection guide

Use these decision points when choosing a model.

1
Prioritize it for an established 1.5 workflow

For a new project, compare the same inputs with OpenAI's current GPT Image 2 rather than treating a deprecated model as the default.

2
GPT Image: Best for fine control

Kyeo's 4o Image page is a lower-credit generation-only route, while Nano Banana Pro has different aspect-ratio, resolution, and reference limits. Test the same brief and choose by success rate, latency, and credits.

3
Use the minimum validation path

First confirm that the edit is understood, preserved regions remain intact, and the direction is correct. Then rerun the same input at `high` to see whether the improvement justifies the extra 18 credits.

Practical usage insights

Practical guidance based on public sources, current on-site limits, and representative tasks.

The official model status has changed

GPT Image 1.5 / The official model status has changed — OpenAI now lists GPT Image 1.5 as a deprecated previous image model and GPT Image 2 as the current image model. Any 1.5 overview should state that lifecycle status instead of calling it the flagship option.

Direct OpenAI controls are not Kyeo controls

GPT Image 1.5 / Direct OpenAI controls are not Kyeo controls — Kyeo exposes 3 aspect ratios and two quality tiers, not every control in OpenAI's direct image API.

Capabilities

Does GPT Image 1.5 support image-to-image editing on Kyeo AI? / GPT Image 1.5

Does GPT Image 1.5 support image-to-image editing on Kyeo AI? / GPT Image 1.5 — GPT Image 1.5 on Kyeo supports text-to-image and image-to-image with three aspect ratios and medium/high quality. Image editing accepts up to 16 JPG, PNG, or WebP references at 10 MB each. Medium costs 4 credits and high costs 22 credits.

Documented reference-image limits

Documented reference-image limits — Up to 16 images, 10 MB each

Quality also selects the credit tier

Quality also selects the credit tier — Generation and editing both offer `medium / high` at 4 / 22 Kyeo credits. Quality is a request and billing setting, not a warranty of accuracy, consistency, or production readiness.

Use cases

GPT Image: Everyday creation

Create social graphics, concept frames, or product mockups from a written brief, then inspect text, layout, and brand details before use.

Targeted edits to an existing image

Test object replacement, background changes, palette adjustments, or recomposition, then inspect text, preserved regions, and layout manually.

Multi-reference experiments

Provide separate sources for a subject, material, palette, or setting, starting with the minimum needed and verifying how the model interprets each one.

Prompt tips

Write edits in preserve, replace, and add order

List elements that must stay unchanged before replacements and additions, including positions and relationships. Inspect the result for unintended changes.

Assign a role to every reference image

Refer to upload order and state which image controls the subject, clothing, background, or material.

Compare medium and high with fixed inputs

Keep the prompt and references identical, then record differences in detail, text, composition, and failure rate. Upgrade only if the evidence supports the extra 18 credits.

Why choose it

Runtime / GPT Image 1.5 — GPT Image 1.5 on Kyeo supports text-to-image and image-to-image with three aspect ratios and medium/high quality. Image editing accepts up to 16 JPG, PNG, or WebP references at 10 MB each. Medium costs 4 credits and high costs 22 credits.
Upload limit — Up to 16 images, 10 MB each
Credit cost — Medium and high credits are explicit, enabling controlled cost comparisons with identical inputs.
Integration / GPT Image 1.5 — The previous model remains useful for regression tests against established 1.5 workflows.

What to know first

Runtime / GPT Image 1.5 — OpenAI marks GPT Image 1.5 as a deprecated previous model; new work should also evaluate a current model.
GPT Image 1.5 / Aspect ratio — Kyeo exposes 3 aspect ratios and two quality tiers, not every control in OpenAI's direct image API.
Credit cost — The high tier costs substantially more, so it is not suitable for large batches of trial-and-error from the outset.
Integration / GPT Image 1.5 — GPT Image can still miss exact text, cross-generation consistency, or precise layouts; high does not remove those limits.

Credit usage

4–22 credits per request

Kyeo AI charges 4 credits for `medium` and 22 credits for `high`.

Budget tip

Before batch generation, run an A/B test with the same assets across the current model and alternatives to validate quality and avoid wasting credits.
