About this model

Kolibri 1 is Aleph Alpha's open-weight mixture-of-experts reasoning model, released in October 2026 under the Apache 2.0 licence. It holds 78 billion parameters, of which about 3.5 billion are active per token, and focuses on German and English, with a tokenizer tailored to German word structure. Its model card describes an explicit reasoning mode and native tool calling, a native context of 262,144 tokens, and positions it for retrieval-augmented generation, agentic tool calling, coding and German- and English-language assistants. It reads text only. Aleph Alpha states it signed the EU General-Purpose AI Code of Practice.

Jurisdiction
EU — AKI.IO states inference runs on GPUs in German data centres (AIME GmbH, Berlin; trust level TL5). AKI.IO confirmed in writing on 13 October 2026 that every model served today on its API is TL5 (hosted by AKI.IO in Germany, zero retention, no training). The Alibaba Cloud (Singapore, TL1) entry on its sub-processor list is for marketplace models not launched yet; these will carry their trust level in the model name
Deployment
Managed cloud inference (AIME GPU cloud, Germany)
Data retention
None at Frontière AI; AKI.IO states prompts and outputs are processed in volatile memory and not logged, stored or analysed

Frontière AI retains neither prompts nor completions from API calls; processing is structured to fit a short DPA (Art. 28 GDPR). DPA and subprocessor documentation available on request.

What its label means

This model is run by a French provider (OVHcloud or Scaleway), in data centres in France. It is not a US company, so the CLOUD Act does not reach it the way it reaches a US provider, and under GDPR a foreign court order is only enforceable in the EU through an international agreement (Article 48). That is the SecNumCloud principle — who controls the operator matters more than where the servers sit — applied as a label, not a qualification: this service is not SecNumCloud-qualified. Our gateway runs in Vercel's Paris region (a US company): your prompts pass through it without being stored.
