}'GPT Image models and prices
GPT Image on varg starts from $0.01 per run (GPT Image 2.5). Prices are in US dollars and are the provider's own, with no markup. A "from" price is the cheapest request the catalog states for that model; each model's page has every rate and input. The descriptions are the catalog's own, shortened.

Every model is billed at its provider's price with no markup, from one credit balance: 1 credit is $0.01. varg's fee is on the top-up, not on the run: 5.5% of the credits you buy ($0.80 at the least), or 8% for a team workspace. Pricing

GPT Image API: questions
- How much does the GPT Image API cost on varg?
- The lowest price the catalog states in the GPT Image family is from $0.01 per run, on GPT Image 2.5 and GPT Image 1. Every model is billed at its provider's price with no markup, from one credit balance: 1 credit is $0.01. For the exact price of a request before you run it, send the same body to POST https://api.varg.ai/v2/estimate.
- Which GPT Image models are on varg?
- 9: GPT Image 2.5 (from $0.01 per run), GPT Image 2.6 (from $0.03 per run), GPT Image 2.5 Flare (from $0.02 per run), GPT Image 2.5 Sunburst (from $0.02 per run), GPT Image 2 (from $0.02 per run), GPT Image 1.5 (from $0.02 per run), GPT Image 1 (from $0.01 per run), GPT Image 1 Mini (from $0.02 per run) and ChatGPT Image (latest) (from $0.02 per run). Each has its own page with the parameters and a call to copy.
- Which GPT Image models take an image?
- All 9: GPT Image 2.5, GPT Image 2.6, GPT Image 2.5 Flare, GPT Image 2.5 Sunburst, GPT Image 2, GPT Image 1.5, GPT Image 1, GPT Image 1 Mini and ChatGPT Image (latest). The catalog lists image to image for them; pass the image as a URL in "files".
- How long do GPT Image requests take?
- Typically from about 15 s (GPT Image 2.6) to about 60 s (GPT Image 2.5 Sunburst), by the catalog's estimates for each model's fastest route. The API answers at once with a job id, so nothing waits on an open connection while it runs.
- How do I call the GPT Image API?
- Send POST https://api.varg.ai/v2/tools/image/call with the header "Authorization: Bearer $VARG_API_KEY" and a JSON body that includes "model", for example "model": "gpt_image_2_5". The call answers 202 with a job right away. Poll GET https://api.varg.ai/v2/jobs/{id} until "status" is "completed", then read output.outputs[0].url, or pass options.webhook_url to be called back.
- Can I use GPT Image from Claude, ChatGPT or Cursor?
- Yes. Add the varg MCP server (https://mcp.varg.ai/mcp) to Claude, ChatGPT, Cursor or any other MCP client and sign in with varg, with no API key to paste. The agent runs a model with call_tool, passing tool "image" and the model id, for example "model": "gpt_image_2_5".
