qwen/image-editimage-to-image13 paramsThe only Qwen endpoint with num_images and sync_mode. num_images is an enum of STRINGS. Its step ceiling is 49, not the 250 its siblings allow, and guidance defaults to 4 rather than 2.5. DOC CONFLICT (two on one page): num_inference_steps prose says "Default value: 30" while the schema says 25 — the schema is what the server reads, so 25 is recorded. acceleration prose says "Options: 'none', 'regular'" while the schema enum is none/regular/high — the enum is recorded. Prompt ceiling is 2000 here and 5000 on both other Qwen 1 endpoints.
