Vienna Startup Cortecs Launches European Secure LLM Platform
Cortecs, a spin-off of the University of Vienna founded in 2021, has launched Sky Inference, a platform that enables companies to use large language models (LLMs) within a European cloud environment. Initially focused on a machine-learning algorithm for crypto-trading tips, the startup pivoted to secure LLM deployment in 2022, targeting clients with high security requirements such as state and critical-infrastructure organizations. Launched on May 26, 2025, Sky Inference routes user requests to models including Mistral, Llama, and DeepSeek across a European value chain, avoiding exposure to the US Cloud Act. Co-founder and CEO Markus Tretzmüller said the platform aggregates existing European AI capacities and aims to process one trillion tokens per month by mid-2026. The company currently employs five people and plans to expand its model lineup continuously.
Cortecs' Sky Inference launch strengthens European AI infrastructure for secure, data-sovereign LLM usage, but as a small startup product launch, its immediate impact on the AdTech/MarTech industry is limited.

Ecosia Drops Mistral for Chinese Open-Source AI
European search engine Ecosia has switched its AI supplier from French startup Mistral to open models, including Chinese ones like Alibaba's Qwen, Z.ai's GLM, and Moonshot AI's Kimi. CEO Christian Kroll cited disappointment with Mistral's model quality, which he says lags about a year behind competitors, and frequent server overloads. Ecosia now uses models via German platform Melious, which runs open AI models on EU servers, halving AI service costs while improving performance. The switch comes as Mistral released Large 4, its most powerful model yet, trained in Europe with open weights due in October. Despite scoring 38.4 on the Intelligence Index, it ranks eighth among open models, behind seven Chinese models. The case highlights the European AI sovereignty dilemma: top-tier open models are predominantly Chinese, even when run on European servers. Mistral itself hosts Chinese models like GLM on its neocloud platform, while its CEO Arthur Mensch defends Large 4's capabilities in areas like cyber defense.
Ecosia Switches from Mistral to Chinese AI Models
Berlin-based search engine Ecosia has replaced French AI provider Mistral with open-weight models, including Chinese ones like Qwen, GLM, and Kimi, as reported by Politico. Ecosia CEO Christian Kroll clarified that the switch is driven by cost, energy efficiency, and the benefits of open models, not a move toward Chinese technology. He criticized Mistral's quality, noting it lags competitors by about a year, and questioned its European sovereignty due to reliance on international investors. The models are now sourced via German platform Melious, which runs open AI models on European servers using green electricity, halving costs while improving performance. Kroll emphasized that Ecosia can switch models for sensitive topics to avoid political biases. Meanwhile, Mistral released Large 4, a trillion-parameter model ranking 8th among open models, with the top seven being Chinese, highlighting Europe's AI sovereignty dilemma.
Anthropic launches cheaper AI model Sonnet 5.5
Anthropic expanded its Claude 5.5 series with Sonnet 5.5 and Haiku 5.5, featuring cost reductions and performance gains. Sonnet 5.5 is 30% faster and up to 30% cheaper, priced at $2/$10 per million tokens. Haiku 5.5, designed for high-volume agentic tasks, is priced at $0.10/$0.50 per million tokens (under 100K tokens), scores 43 on the Artificial Analysis Intelligence Index (surpassing GPT-6 Luna and Gemini 3.8 Flash), supports 1M-token context, and introduces effort settings. A new tokenizer counts 30% more tokens, but costs are 75% lower. Both models are available on major platforms with integrations. Other AI news includes OpenAI's release of 719 math papers from an unreleased model, Mistral's Le Chonk and Reflection AI's Beam open-weight models, an OpenAI researcher's resignation, Google's public SynthID, OpenAI's EU watermarking, and industry moves like TikTok's shopping assistant and ElevenLabs' valuation doubling.
