GPT Image 1
openaiopenai/gpt-image-1
How TheRouter serves this differently from the vendor
As the vendor operates it
OpenAI serves direct gpt-image-1 calls on /v1/images/generations and /v1/images/edits, and its model page also lists /v1/responses support for the model ID.
On TheRouter
TheRouter exposes image generation and image edit for openai/gpt-image-1 under https://api.therouter.ai/v1. Use the OpenAI SDK shape with TheRouter baseURL, API key, and routed model slug; do not assume chat/completions works for this image model.
