List AI models

Every model an AI op can run on, across the providers behind this API. A model runs an op when its categories include the op's modelCategory (GET /api/v1/ops); naming any other model is 400 invalid_param, with the models that fit in details.allowed. Leave model out and the op's defaultModel runs.

Each entry carries its price per image after markup (priceRange) beside the provider's own list price (providerPrice, providerPriceRange), the parameters it takes (params, in the op catalogue's shape), and maxInputEdge / maxInputImages — how big an input it is handed and how many images one call takes (what bounds a preset's reference images). The exact price of one request is the dry run.

The snake_case names, parameters, supported_parameters and created are deprecated and go on 2027-01-12 (https://imagestep.dev/docs/changelog#2026-10-14-model-fields): until then every answer carries both names, and Deprecation / Sunset / Link headers that say so.

USE THIS WHEN:

• Choosing a model for an AI op, or checking one before a submit
• Checking what a model costs, or how many reference images it takes

DO NOT USE WHEN:

• You want each op's default model and its price → GET /api/v1/ops, which carries them
