About the GPT Image 1.5 API

How much does the GPT Image 1.5 API cost?

GPT Image 1.5 costs from $0.01 per image on Revana (1:1-high: $0.11; 1:1-low: $0.01; 1:1-medium: $0.03; 2:3-high: $0.16; 2:3-low: $0.02; 2:3-medium: $0.04; more in the price table). You pay in prepaid credits, 100 credits to the dollar, with no subscription or monthly minimum. A generation that fails costs nothing.

How do I call GPT Image 1.5 from code?

Send POST https://api.revana.si/v1/generations with {"model": "gpt-image-1.5", "input": {...}} and your Revana API key as a Bearer token, poll GET /v1/generations/{id} until it succeeds, then download GET /v1/generations/{id}/content. Every model on Revana takes the same request shape.

What happens if a GPT Image 1.5 generation fails?

You are charged once, only for the route that delivers. A failed generation costs $0.00.

What can GPT Image 1.5 do on Revana?

GPT Image 1.5 supports text to image and image to image, aspect ratios 1:1, 3:2, 2:3 and up to 15 input images. A value it does not offer is refused with 422 before anything is charged.

Can my AI agent use GPT Image 1.5?

Yes. Connect the Revana MCP server (https://revana.si/api/mcp) to Claude, ChatGPT, Cursor or Codex, or have the agent call the REST API. The agent can list models, get a free quote and generate on your credits.
