How do I send an image to GPT-4o for analysis?

Short answer: You can analyze image in OpenAI by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the OpenAI Analyze Image action to a workflow, map its 4 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about Analyze Image.

What does the Analyze Image action do in OpenAI?

Analyzes an image using GPT-4o vision, accepting a URL or base64-encoded image plus a text prompt. Use for OCR, chart extraction, alt-text generation, or visual QA.

What inputs does Analyze Image require?

Required: Model, Image URL, Prompt. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if OpenAI returns an error?

The run history shows the failed step with its input and the error message OpenAI returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does Analyze Image support batch operations?

Run Analyze Image inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within OpenAI's rate limits.
