Southeast Asia, where the two lists diverge
Indonesian appears in both declared lists. Filipino, Malay, Thai and Vietnamese appear only in Kling AI's 20. This is the region where the two declared lists differ most, and the difference is four languages wide. As of 2026-09-12.
| Vendor | Codes declared | Note |
|---|---|---|
| Declared by both | id | Indonesian |
| Declared by Kling AI only | fil, ms, th, vi | Filipino, Malay, Thai, Vietnamese |
| Declared by neither | Everything else in the region | Including Khmer, Lao, Burmese |
Inclusion rule. Only languages declared as same-domain hreflang alternates are listed. Product-side coverage is not shown per language because neither vendor enumerates its spoken-language list. Order. Vendors that declare the market first, then what neither declares.
1The widest declared coverage in the register points here
A vendor declaring Filipino, Malay, Thai and Vietnamese alongside the usual European set is making a statement about where it expects buyers to be. Site languages are a marketing artefact, and marketing artefacts are unusually honest about a company's actual commercial attention.
For a producer working in these markets that is a real signal, and it is a signal about where support and documentation will exist rather than about what the model can speak.
2Four languages of divergence is the largest gap in the register
Everywhere else the two declared lists mostly agree. Here one vendor covers four languages the other does not, which makes this the clearest case of the register's central point: declared site coverage is a business decision and it varies by vendor far more than product capability plausibly does.
Nothing in either vendor's published material says their models cannot speak these languages. The difference recorded here is about which pages exist, and that is all it is.
3What the region's absent languages tell you
Khmer, Lao and Burmese appear in no declared list in this register. For anyone producing in those markets the published answer across all eight tools is the same: nothing, in any column.
That is worth stating because a reader scanning a 20-language list can reasonably assume their market is in there somewhere. The list is long and it stops well short of the region.
