gpt-image-1 is OpenAI's earlier natively multimodal image generation model: it accepts both text and image inputs and produces image outputs, with low, medium, and high quality tiers and three resolution options.
- Now listed as a previous-generation model superseded by gpt-image-1.5 and gpt-image-2, it remains available for backward compatibility and for pipelines tuned to its output characteristics.
- Synthorai keeps gpt-image-1 selectable through its OpenAI-compatible image generation endpoint, so legacy integrations keep working without changes.

FAQ
Is the GPT Image 1 API free to try?
Yes: new accounts get 10 trial calls and up to $1 in free credit, no card required. That's enough to try GPT Image 1 against your real workload before adding a payment method.
What is GPT Image 1 best at?
Natively multimodal text and image inputs, plus three quality tiers and resolution options and kept available for backward compatibility. See the About section for the full picture from the vendor's own release notes.
How much does GPT Image 1 cost?
GPT Image 1 costs $5 per million input tokens and $40 per million output tokens on Synthorai. That is the provider's list price, with no platform markup.
How do I generate images with the GPT Image 1 API?
POST to /v1/images/generations on Synthorai with model="gpt-image-1". It follows the OpenAI images API shape, so no vendor SDK is needed.
How do I get access to GPT Image 1?
Point your existing OpenAI SDK at base_url="https://synthorai.io/v1", set model="gpt-image-1", and you're done. One API key covers every model on the gateway.
