Chunked uploading is a feature (should work in Firefox and Chrome) that splits an upload into 1MB chunks to ensure that a large file can be transferred reliably. With chunked uploading enabled you can upload up to 500MB files.
See the experimental preference in the "Upload Wizard" section: https://commons.wikimedia.org/wiki/Special:Preferences#mw-prefsection-upload...
You need to use Upload Wizard in order to use this feature.
This has required some significant changes to the way uploads are handled by the API to avoid timeouts, so it's likely to still be fragile. Do play with it, and in particular comment on these bugs if you have useful observations to share:

All best, Erik

Thanks Erik - I've some large files to upload and I'll try them with this. Do you know if there's any chance it will be able to work with the API in future, for bot-assisted uploads?

This is already possible with API, even though I've never tried: see https://bugzilla.wikimedia.org/show_bug.cgi?id=36587#c12 which is about tests with https://commons.wikimedia.org/wiki/Commons:Up!.
