Privacy: The Critical Difference
This is where Tensorx fundamentally differs from both OpenAI and Anthropic:
🇺🇸 OpenAI & Anthropic
US-based companies subject to the CLOUD Act. Data may be retained for 30+ days. Training opt-out available but not default. GDPR compliance is contractual, not architectural.
🇪🇺 Tensorx
EU-based infrastructure in Dublin and Helsinki. Zero data retention — prompts are processed and immediately discarded. GDPR compliance is built into the architecture, not just the contract.
Model Quality Comparison
The common assumption is that OpenAI and Anthropic have better models. The reality is more nuanced:

Cost Comparison
The cost difference is dramatic:
- OpenAI GPT-4o: $5/$15 per 1M tokens (input/output)
- Anthropic Claude 3.5 Sonnet: $3/$15 per 1M tokens
- Tensorx MiniMax-M2.5: $0.40/$1.60 per 1M tokens
- Tensorx GLM-5: $0.14/$0.28 per 1M tokens
⚠️ Cost Reality
For most use cases, Tensorx models deliver equivalent quality at 60–97% lower cost. The performance gap between frontier models and open-source models has narrowed dramatically in 2025.
