Gemini | Vision

Gemini can understand and analyze images. You can send images as base64-encoded data within content parts.

Vision Example

Send a base64-encoded image to Gemini for analysis.

Gemini := TsgcHTTP_API_Gemini.Create(nil);
Gemini.GeminiOptions.ApiKey := 'API_KEY';

// Load image and encode to base64
oStream := TFileStream.Create('photo.jpg', fmOpenRead);
Try
  oBytes := TBytesStream.Create;
  Try
    oBytes.CopyFrom(oStream, 0);
    vImageBase64 := EncodeBase64(oBytes.Memory, oBytes.Size);
  Finally
    oBytes.Free;
  End;
Finally
  oStream.Free;
End;

WriteLn(Gemini._CreateVisionContent('gemini-2.0-flash',
  'Describe this image', vImageBase64, 'image/jpeg'));
