ASEAN-region availability and pricing notes coming soon. Drop the editorial team a note via /contact/ if you can supply local context (Singapore/Malaysia/Indonesia/Thailand/Vietnam).
Shisa.ai is a notable small-team Japanese LLM lab that ships genuinely open weights plus a practical translation/speech API stack, punching above its size on Japanese benchmarks. The open-weight stance makes it attractive for builders who want Japanese capability without lock-in.
As a young, lean company its enterprise maturity and support depth are less proven than larger rivals, and its focus is squarely Japanese-language. For Japanese open-model work it is a compelling, developer-friendly option.
