# GPT Image 2 image edit

Needs prompt and image urls. Served by fal.ai.

GPT Image 2 (OpenAI), image edit, served by fal.ai. The OpenAPI schema for the openai/gpt-image-2/edit queue. Price: Billed on image tokens; fal's canonical table gives per image (low / medium / high): 1024x768 $0.005 / $0.037 / $0.145, 1024x1024 $0.006 / $0.053 / $0.211, 1024x1536 $0.005 / $0.042 / $0.165, 1920x1080 $0.005 / $0.040 / $0.158, 2560x1440 $0.007 / $0.056 / $0.222, 3840x2160 $0.012 / $0.101 / $0.401. Presets other than square_hd render at 0.66 to 0.79 megapixel (measured 2026-09-04: square 816x816, 4:3 1024x768, 16:9 1088x608) and are priced at the 1024x768 tier; explicit sizes are the canonical ones in either orientation. Text tokens $5 per 1M input: $0.002 allowance per call. 'auto' size and quality are not offered: not priceable in advance. Input image tokens $8 per 1M: $0.012 allowance per call. Waits up to 40 s for the result; if the generation takes longer, the run stays RUNNING and returns a request_id; poll fal/status and fetch fal/result with model "openai/gpt-image-2" and that request_id. Billed once, when the result is ready; a generation that fails is refunded.

## Execute and retrieve

Inspect again before execution, explain the price and obtain the required authority. Use MCP run_tool or POST /v1/run with this tool ID, valid input and an idempotency key. Save the returned run ID and follow the actual state. If Agentik answers that the tool is temporarily unavailable, do not retry it blindly; use discovery to propose an alternative.

This tool uses deferred settlement. Follow its returned task/run instructions; preserve the existing reservation until the result is reconciled.

A partial or uncertain result can still have consumed provider resources. Consult [billing](/docs/billing.md), [idempotency](/docs/idempotency.md) and [asynchronous results](/docs/async.md).
