How do I batch process 100 product photos with Firefly?

Batch processing 100 images in a generative AI tool like Firefly isn't a simple cron job. You're likely looking at a manual, API-driven, or scripted workflow, each with its own failure modes and reliability concerns.

First, define your SLIs for this batch job. What's acceptable?
* Success rate: 95% of images processed without manual intervention?
* Latency: Complete within 2 hours?
* Consistency: Output quality/style variance below a defined threshold?

Firefly's primary interfaces are the web UI and the API. The UI is not built for 100-unit batch operations—you'll be clicking forever. The API is your only realistic path. You'll need to handle:
* Authentication and rate limits (your SLA is zero if you get throttled).
* Input/output asset management (pre-processing, uploading, downloading, organizing).
* Error handling and retries for API calls (network blips, content policy rejections).

A skeletal workflow might look like this, assuming you have some scripting skills:

```bash
# Pseudocode overview
1. Pre-process images (resize, standardize) locally.
2. For each image in /input_dir:
a. Upload to a cloud storage URL accessible to Firefly API.
b. Call Firefly API (e.g., Generative Fill, Text to Image) with params.
c. Poll for job completion.
d. On success, download result to /output_dir.
e. On repeated failure, log error and move image to /failed_dir.
3. Generate a run report: success count, failure list, total time.
```

Key pitfalls:
* Cost: 100 images via API isn't free. Calculate your cost per unit.
* Observability: You must instrument your script. Log every step. Without logs, you can't measure your SLIs or debug when 30 images silently fail.
* Idempotency: If your script crashes at image 57, can you restart without re-processing 1-56 or creating duplicates?
* Output quality SLO: How do you verify the generative results are consistent? Manual spot-check? Some automated image similarity check? This is often the hardest part.

If you don't have the engineering bandwidth to build this pipeline with proper monitoring and error handling, you might be better off with a dedicated batch image processing service, even if it's not generative AI. Firefly's strength is creative iteration, not operational batch reliability.
