This guide is intentionally practical. It focuses on the request and output patterns you will actually use in Memories.ai, not external benchmark scoreboards.
Quick Picks
Best default
Start with Gemini Image if you want one strong default for image reasoning and schema-based extraction.
Simplest JSON path
Start with GPT Image if you want the most familiar documented
response_format path for JSON output.Lowest-cost batch

Tool-first extraction
Start with Nova Image if your workflow is built around tool-style extraction via
toolConfig.Choose By Workflow
Provider Differences That Matter
Suggested Starting Models
Qwen source pricing is documented per
1K tokens on its provider pages. This guide converts the lowest published tier into 1M token terms for faster cross-provider comparison.How To Evaluate On Your Own Data
Before standardizing on an image model, compare at least these cases:- clean product or document images vs noisy real-world photos
- captioning vs field extraction
- free-form output vs strict JSON output
- small interactive workloads vs bulk batch processing
