European alternatives to ChatGPT
ChatGPT by OpenAI is the best-known AI assistant, but processes data in the US. For companies with privacy requirements, there are European AI providers.
Why look for an alternative?
Reasons include European data processing, control over whether inputs are used for training and the option of self-hosting or open model weights.
What to look for in an alternative
- European provider headquarters and EU data processing
- Assurance that inputs are not used for training
- Model quality for the specific use case
- Self-hosting or open weights if needed
- Transparent prices per token
The best European alternatives at a glance
Sorted by suitability as a replacement for the tool you searched. The Sovereignty Score independently rates how European and data-sovereign a provider is – so the two values can differ.
French AI provider with powerful language models – partly with open weights and EU processing.
German AI provider focused on sovereign, on-premise-capable language models for companies and public authorities.
Comparison table
| Providers | Fit | Sovereignty | Headquarters | Open Source | Self-hosting | EU hosting | Pricing |
|---|---|---|---|---|---|---|---|
| Mistral AI | 84 | 82 | France | API (pay-per-token) / Le Chat Pro | |||
| Aleph Alpha | 78 | 86 | Germany | Enterprise / API |
The top providers in detail
Mistral AI is the best-known European provider of large language models. In addition to commercial models, Mistral releases numerous models with open weights under the Apache 2.0 license and offers an API whose processing takes place by default in the EU (Paris region) – US routing only as an opt-in. The provider is certified according to ISO/IEC 27001/27701 and SOC 2 Type II. Billing is usage-based per token; the Le Chat Pro subscription costs around $14.99 per month. For teams that want to use generative AI in a GDPR-oriented way, Mistral is an obvious alternative to US providers.
Strengths
- Powerful models from an EU provider
- Partly open model weights, also self-hostable
- European data processing via the API
Weaknesses
- Ecosystem and tooling are younger than with US providers
- Not all models are openly available
Aleph Alpha from Heidelberg targets companies and the public sector with high requirements for data sovereignty. The focus is on sovereign, EU AI Act-oriented AI that can also be operated on-premise, as well as model explainability (products: Luminous models, Pharia AI stack). The provider is ISO/IEC 27001 certified. Note the merger with Canadian provider Cohere announced in April 2026, which may change the ownership structure in future. Aleph Alpha therefore primarily addresses regulated industries and public authorities.
Strengths
- German provider with a sovereignty focus
- On-premise operation possible
- Aimed at regulated industries and public authorities
Weaknesses
- Primarily enterprise, little for small teams
- Less public pricing and product information
Migration effort
| Providers | Migration effort | Fit |
|---|---|---|
| Mistral AI | medium | 84/100 |
| Aleph Alpha | high | 78/100 |
When switching pays off
For GDPR-oriented generative AI, Mistral AI is the obvious API alternative. For high sovereignty requirements and on-premise operation, Aleph Alpha is an option.
When to stick with your current tool
If your use case strictly requires a specific OpenAI model or its ecosystem, first check whether a European model reaches the required quality.
