tl;dr: Aleph Alpha released Kolibri, an Apache 2.0-licensed 78B-parameter (3B active) English-German MoE Transformer with up to 1M token context, targeting sovereign, regulated deployments like German public sector, aerospace, and industrials. The model was trained in Germany/Finland on 768 B200 GPUs over ~24T tokens using a custom bilingual tokenizer, Merlin-Arthur grounding to reduce hallucinations, and curated German data (21% of pretraining). Aleph Alpha claims Kolibri sits on the quality/cost Pareto frontier and matches models with 4x its active parameters on math, code, and long-context benchmarks.
HN Discussion:
  • ↑Appreciation for the unprecedented openness and transparency of the technical documentation and release
  • ↓Sovereignty claim is misleading given the pending Cohere acquisition and Canadian ownership
  • ↓Benchmark comparisons are cherry-picked, omitting stronger competitors like Qwen3.8 Flash
  • ↑The model's real value lies in non-coding business processes like German-language support automation, not benchmarks
  • ~Sovereign models are most useful as auditors/trust-adapters for other open models rather than primary workhorses
