# Synthetic Image Evaluator

> Evaluates whether an image was generated by AI or captured by a camera/created by humans.

<CodeGroup>
  ```python Python theme={null}
  result = evaluator.evaluate(
      eval_templates="synthetic_image_evaluator",
      inputs={
          "image": "https://www.esparklearning.com/app/uploads/2024/04/Albert-Einstein-generated-by-AI-1024x683.webp"
      },
      model_name="turing_flash"
  )

  print(result.eval_results[0].output)
  print(result.eval_results[0].reason)
  ```

  ```typescript JS/TS theme={null}
  import { Evaluator, Templates } from "@future-agi/ai-evaluation";

  const evaluator = new Evaluator();

  const result = await evaluator.evaluate(
    "synthetic_image_evaluator",
    {
      image: "https://www.esparklearning.com/app/uploads/2024/04/Albert-Einstein-generated-by-AI-1024x683.webp"
    },

      modelName: "turing_flash",
    }

  console.log(result);
  ```

| **Input** |                    |          |                                                |
| --------- | ------------------ | -------- | ---------------------------------------------- |
|           | **Required Input** | **Type** | **Description**                                |
|           | `image`            | `string` | URL or file path to the image to be evaluated. |

| **Output** |            |                                                                                                                                    |

|            | **Result** | Returns Score representing the synthetic image evaluator, where higher values indicate confidence in the image being AI-generated. |
|            | **Reason** | Provides a detailed explanation of why the image was classified as AI-generated or not.                                            |

### What to do If you get Undesired Results

If you're evaluating images and the results don't match your expectations:

* For actual photographs mistakenly identified as synthetic:
  * Ensure the image has not been heavily processed or filtered
  * Check that the image doesn't have unusual artifacts from compression or editing
  * Consider providing higher resolution versions if available

* For synthetic images not being detected:
  * Be aware that newer AI generation models are becoming increasingly photorealistic
  * Some AI-generated images that were post-processed or combined with real photographs may be harder to detect
  * The evaluation works best with full images rather than small crops or heavily modified versions

### Comparing Synthetic Image Evaluator with Similar Evals

* [**Caption Hallucination**](/future-agi/get-started/evaluation/builtin-evals/caption-hallucination): While Synthetic Image Evaluator determines if an image was artificially created, Caption Hallucination evaluates whether descriptions of images contain fabricated elements not visible in the image.
* [**Toxicity**](/future-agi/get-started/evaluation/builtin-evals/toxicity): Synthetic Image Evaluator focuses on the creation method of images, whereas Toxicity evaluates whether content contains harmful elements.
