Update April 2026: Cohere (Canada) announced the acquisition of and merger with Aleph Alpha on 24 April 2026 — combined valuation of approximately USD 20bn, anchored by a USD 600m investment from the Schwarz Group. The German and Canadian governments backed the deal under the Canada-Germany Sovereign Technology Alliance. Aleph Alpha shareholders hold approximately 10% of the combined entity.
As AI consultants based in Rosenheim, Germany, we recommend Aleph Alpha Luminous as the most sovereign AI option for European enterprises and government agencies. As Germany’s only foundation model company, Aleph Alpha offers maximum data sovereignty and with the T-Free architecture, pioneering technology.
Note: Since late 2024, Aleph Alpha has pivoted from directly marketing the Luminous LLM API to new customers, instead focusing on the PhariaAI enterprise platform. The Luminous API is no longer actively marketed to new customers. Existing deployments continue to be supported.

T-Free: Revolutionary Architecture (2025)
In January 2025, Aleph Alpha presented the T-Free architecture - a paradigm shift in Large Language Models:
What is T-Free?
T-Free (Tokenizer-Free) completely eliminates traditional tokenizers and processes text directly at the character level:
- 85% Fewer Parameters: Drastically reduced embedding layers
- Up to 200% Faster: Especially for non-English languages
- Universal: Works with all languages and specialized vocabularies
- Adaptive: Perfect for specialized domains and low-resource languages
T-Free Architecture Benefits
- Language Fairness: No more preference for certain languages
- Efficiency: Less computational overhead, lower costs
- Flexibility: Easy fine-tuning for new domains
- Sovereignty: Ideal for European and German special requirements
T-Free models are already available as open-source (Hugging Face: tfree-hat-pretrained-7b-base).
Key Strengths

Merger with Cohere (April 2026)
On 24 April 2026, Canadian AI company Cohere announced the acquisition of and merger with Aleph Alpha. Key facts:
- Combined valuation approximately USD 20bn – combining Cohere’s USD 7bn pre-deal valuation, Aleph Alpha’s USD 3bn book value and a Series E round
- USD 600m strategic investment from Schwarz Group (Lidl/Kaufland) – anchoring the European sovereign-AI strategy
- Ownership: Cohere ~90%, Aleph Alpha ~10% of the combined entity
- Political backing: Canada-Germany Sovereign Technology Alliance – the digital ministers of both countries attended the Berlin announcement
- Strategy: Cohere brings the core LLM stack, Aleph Alpha brings German-language tokenizer/SLM expertise and government relationships
What this means for existing customers: existing contracts continue in the short term. Aleph Alpha’s Pharia stack and the Schwarz cloud partnership remain the German-language sovereign-AI offer. For new projects, we recommend actively monitoring the product roadmap of the combined organisation.

Our Recommendation
For new projects, Pharia-1 LLM-7B (Apache 2.0, EU-compliant, self-hostable) is the strategic recommendation from the Aleph Alpha portfolio. The Luminous models are no longer actively marketed to new customers and should only be retained in existing projects. The new T-Free architecture also demonstrates that Aleph Alpha is technologically leading and not just focused on sovereignty, but also on innovation.
For organizations where data sovereignty is more important than maximum model performance, Aleph Alpha remains a key choice. Please note: After the Cohere merger (April 2026), a new transatlantic sovereign-AI offering is being built — we recommend actively monitoring the product roadmap of the combined organisation.
For general enterprise applications without special security requirements, we alternatively recommend Mistral AI as a European option or OpenAI GPT via Azure Germany.
