image-generation Specification

Purpose

TBD - created by archiving change add-gpt-image-edit-support. Update Purpose after archive.

Requirements

Requirement: Support Official GPT Image Edit Requests

The system SHALL send official GPT Image edit requests to /images/edits when an official GPT Image profile is selected and the image request includes edit inputs.

Scenario: Reference-image request uses edit endpoint

GIVEN a provider profile resolves image API compatibility to openai-gpt-image
AND the selected model is a GPT Image model
AND the image request includes at least one reference image
WHEN the image task is executed
THEN the GPT Image adapter SHALL send the request to /images/edits
AND include input images as multipart image[] file fields
AND SHALL NOT include response_format

Scenario: Text-only request remains generation

GIVEN a provider profile resolves image API compatibility to openai-gpt-image
AND the selected model is a GPT Image model
AND the image request has no reference images or edit inputs
WHEN the image task is executed
THEN the GPT Image adapter SHALL send the request to /images/generations

Requirement: Route Tuzi GPT Image Through Dedicated Adapter

The system SHALL route Tuzi GPT Image generation and edit requests through the dedicated Tuzi GPT Image adapter when the selected profile resolves to Tuzi GPT Image compatibility.

Scenario: Tuzi GPT request uses Tuzi adapter

GIVEN a provider profile resolves image API compatibility to tuzi-gpt-image
AND the selected model is a GPT Image model
WHEN the image task is executed
THEN the request SHALL be handled by the dedicated Tuzi GPT Image adapter
AND SHALL NOT rely on GPT-specific translation logic inside the generic default adapter

Requirement: Preserve Generic Basic Compatibility

The system SHALL preserve the default adapter behavior only for generic OpenAI-compatible image gateways that resolve to the basic compatibility mode.

Scenario: Generic compatibility stays basic

GIVEN a provider profile resolves image API compatibility to openai-compatible-basic
WHEN the image task is executed
THEN the request SHALL remain eligible for the default adapter
