Hi @mozik

You can use this n8n expression for the Base64 Input file(s)

{{ $json.choices[0].message.images[0].image_url.url.split(',').pop() }}

Why this works:

• .split(','): This breaks the string into two parts at the comma.

  • Part 1: data:image/png;base64

  • Part 2: The actual Base64 code.

• .pop(): This grabs the last element of that split (the Base64 string), which is exactly what you need for most image processing nodes.

hope this helps.
