Sortio's AI Just Got 5x Faster and Smarter

We shipped a major upgrade to Sortio's AI engine. Every sort you run is now powered by GPT-5.4-mini instead of GPT-4o-mini. Here's what that means, with real benchmarks.

The Numbers

We benchmarked 7 models across 6 test scenarios: 10, 50, and 100 files with and without content analysis. Here are the results that matter.

That's not a typo. Sorting 100 files now takes 17 seconds instead of a minute and a half.

Accuracy

GPT-4o-mini had a critical flaw: at 100 files, it would drop files. It ran out of output capacity before it could sort everything. With GPT-5.4-mini, every file gets sorted, every time.

What This Looks Like in Practice

Here are example prompts and what the new engine produces:

Music Production Workflow

200+ files
> "Separate audio by stems (WAV, mp3, aiff), tracks (WAV, mp3), Ableton Projects. Documents in folders depending on use. Misc in a single folder, organized by type and date."

Result: Audio/Stems, Audio/Tracks, Ableton Projects, Documents/Word-PDF, Media/Audiobooks: domain-specific folders with date-based sub-organization.

Research Paper Library

400+ files
> "Scientific literature in 'Papers' divided by research area. Protocols in their own folder. Data analysis scripts organized by project."

Result: Papers/Field Studies, Papers/Urban Ecology, Protocols, Scripts/Analysis, Data/Raw: academic file organization a researcher would actually use.

Applications Folder

189 files
> "Sort by type like utilities, gaming, system etc"

Result: AI/Chatbots, Audio/Editors, Browsers, Dev, Gaming/Launchers, System/Diagnostics, Utilities/Password Managers: intelligent categorization beyond file extensions.

Works in Any Language

Write your prompt in German, French, Spanish, Turkish: the AI understands and creates folder names in your language.

🇩🇪German
> "Sortiere nach Autoren"

Organized by author name

🇫🇷French
> "Classe les fichiers par catégorie"

Sorted into French-language categories

🇹🇷Turkish
> "Klasörleri türkçe kategorize et"

Turkish folder names

Why We Switched

GPT-4o-mini was Sortio's engine since launch. It was cheap and fast enough, but "fast enough" meant we had to work around a 30-second server timeout by splitting large folders into tiny batches of 10 files, sorting each batch separately, then stitching the results together on your machine.

The problem: each batch only sees 10 files. The AI can't make global decisions about folder structure. It might create "Documents" in batch 1, then "Docs" in batch 3, then "Files" in batch 5, all for the same type of content.

We also moved our entire infrastructure to Google Cloud, removing a 30-second server timeout that previously forced the batching approach. With that constraint gone and GPT-5.4-mini's capabilities, we now send all your files in a single request. The AI sees everything at once and creates one coherent folder structure. No stitching, no duplicates, no missed files.

What This Means for You

Sorts complete in seconds, not minutes. 100 files in 17 seconds.

No more missing files. 100% completion rate at every file count.

Better folder structures. The AI sees all your files at once.

Works in any language. German, French, Turkish, Spanish.
