Reka open-sources Flash 3, a 21B reasoning model powering Nexus
Reka just open-sourced Flash 3, a 21B parameter reasoning model built completely from scratch. Despite its lightweight footprint, Reka claims competitive performance and is already using it as the core engine behind its new enterprise intelligence platform, Nexus.
Reka Flash 3 is a newly open-sourced 21B parameter reasoning model, trained completely from scratch by Reka.
A lightweight reasoning engine
Despite its compact 21B footprint, Reka claims the model delivers competitive performance on complex reasoning tasks.
Alongside releasing the weights to the open-source community, Reka is also putting it straight to work as the core intelligence powering its new enterprise platform, Nexus.
Why it matters
A 21B reasoning model hits a very practical sweet spot for developers and enterprises wanting capable local inference without renting massive GPU clusters.
It is worth watching if you are looking for an efficient self-hosted reasoning backbone. That said, Reka has not yet shared detailed benchmark breakdowns, so its true real-world capabilities remain to be seen once the community stress-tests it.
