Nunki08 · reddit · 2026-10-03

Aleph Alpha released Kolibri-1 on Hugging Face: a sparse MoE model with 78B total parameters but only 3.46B active, up to 1M token context, under the fully permissive Apache 2.0 license. A tech report is available on the company's site — a notable new option for long-context, commercially usable open-source deployments.
