New Sahara-v2.5 is now live

Code switching is here

Our most intelligent voice AI model yet—built to understand how Africa actually
speaks: switching between languages mid-sentence without slowing down.

Code-Switching in 12 African Languages​

People often mix languages in one breath: a Kano trader switches between Hausa and English; a Nairobi patient uses Swahili and English; a Lagos colleague blends Yoruba and Pidgin. Global models see this as an error, but Sahara-v2.5 understands it. It’s the first bilingual code-switching support across 12 African languages, expanding the Swahili-English feature from v2 to the whole continent.
