Leanstral 1.5: 6B open model plus K3 orchestration beats GPT-6 Astra on ArXivLean
sophiamyang · x · 2026-09-11
Internship result spotlighted by sophiamyang: Leanstral 1.5, a 6B open-source model trained with heavy compute ('a lot of grinding') plus a bit of K3 orchestration, beats GPT-6 Astra on the ArXivLean benchmark. The poster notes token counting there is likely erroneous (small models do 'yap'). Work by intern Matéo Pirio Rossignol, mentored by @romansoletskyi.
