Aleph Alpha has introduced Kolibri, an open-weight Mixture-of-Experts (MoE) large language model designed for English and German tasks. With 78.1 billion total parameters, the model selectively activates just 3.46 billion per token, aiming to deliver strong performance at lower inference cost.
The model supports a 1 million-token context window and offers adjustable reasoning effort per request, allowing developers to trade latency for depth. Its Apache 2.0 FP8-quantized weights are optimized to run on a single Nvidia B200 or H200 GPU, broadening access for organizations without large multi-GPU clusters.
Kolibri reflects a broader industry shift toward sparse architectures like MoE, which keep capacity high while limiting compute per token. Aleph Alpha's focus on bilingual English-German capabilities also positions it for European enterprise and public-sector use cases where language compliance matters.
By releasing the weights openly under Apache 2.0, the company encourages local deployment and fine-tuning. This could appeal to privacy-sensitive customers who need on-premises inference rather than cloud-hosted APIs, though real-world throughput and quality will depend on independent benchmarks.
