GPT Image 1.5

GPT Image 1.5 supports generation and editing on Kyeo AI. Text-only requests use `gpt-image/1.5-text-to-image`; attaching references switches to `gpt-image/1.5-image-to-image`. Kyeo exposes 3 aspect ratios and `medium / high` tiers at 4 / 22 credits. OpenAI now marks GPT Image 1.5 as a deprecated previous model, so new work should also benchmark a current model such as GPT Image 2.

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.

At a glance

What is this model like?

Use this page to reproduce an existing GPT Image 1.5 workflow or compare its generation and editing results. It documents the routes, controls, credit prices, and upload rules actually available on Kyeo. The 16-image figure is a request ceiling, not a recommendation or a promise of better subject, text, or layout consistency.

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
Validate the edit at medium quality

Start with `medium` and only the references the task needs, then rerun the identical input at `high`. Pay the 18-credit difference only when measured results justify it.

Practical usage insights

Practical observations based on real creative workflows.

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

OpenAI's image API also documents size, output format, compression, and background controls. Kyeo currently exposes only 3 aspect ratios and two quality tiers, so claims must follow the actual interface.

Capabilities

GPT Image: Clear input options

Text-only requests call `gpt-image/1.5-text-to-image`; adding references calls `gpt-image/1.5-image-to-image`. Both paths share the page's aspect-ratio and quality controls.

Documented reference-image limits

Files may be JPEG, PNG, or WebP and must be 10 MB or smaller each. Sixteen is a ceiling, not a target. Technical identifiers: `input_urls`.

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, material, or color.

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.

Strengths

One Kyeo page supports both generation and reference-image editing.
Upload rules are explicit: up to 16 JPEG, PNG, or WebP images at 10 MB each.
Medium and high credits are explicit, enabling controlled cost comparisons with identical inputs.
The previous model remains useful for regression tests against established 1.5 workflows.

Limitations

OpenAI marks GPT Image 1.5 as a deprecated previous model; new work should also evaluate a current model.
Kyeo exposes 3 aspect ratios and two quality tiers, not every control in OpenAI's direct image API.
Upstream interface and Kyeo do not disclose a prompt character limit or the upstream OpenAI snapshot in use.
GPT Image can still miss exact text, cross-generation consistency, or precise layouts; high does not remove those limits.

Credit usage

4-22 credits / 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.
