Research
Shapourian's Zamba2-VL report, posted in May 2026 with Kasra Hejazi, Olabode M. Sule and Beren Millidge, adapts Zyphra's Zamba2 hybrid state-space language models to image understanding. Zyphra's release post describes the family as competitive with transformer-based open vision-language models of similar size while having lower time-to-first-token.12
The same author group is credited on Zyphra's ZAYA1-VL-8B release from May 2026. Earlier, in March 2024, Shapourian was listed with a Cisco affiliation among the co-authors of Zyphra's post "The Unreasonable Ineffectiveness of the Deeper Layers".34
