Reka Flash 21B is Reka AI's mid-sized multimodal model built to handle vision-language tasks alongside standard text workloads. At 21 billion parameters it occupies an efficiency-oriented position in Reka's lineup, offering multimodal understanding — including image comprehension — without the compute demands of larger frontier models.
Reka positions Flash as a fast, capable model for applications that need both visual and textual reasoning, such as image-grounded Q&A, document understanding with embedded figures, and visual content description. It reflects Reka's focus on building practical, deployable multimodal systems rather than purely language-centric architectures.
