Google released Gemini 2.5 Flash!
The TLDR
Google's Gemini 2.5 Flash is a revolutionary hybrid model that can pause to think like a human, with adjustable "thinking budgets" for developers. Even with thinking disabled, it outperforms Gemini 2.0 Flash, offering better speed, cost-efficiency, and accuracy. The AI intelligently decides when deeper reasoning is needed, excelling in tasks from translation to advanced math. This marks a major step toward adaptive, resource-efficient AI.
Imagine if AI could pause and think like a human before responding—that's exactly what Google is making possible with the new Gemini 2.5 Flash! As the first fully hybrid “thinking model,” this groundbreaking system allows developers to selectively enable or disable thinking processes and even set “thinking budgets.”
The innovative AI masterfully balances speed, cost, and quality. Even with the thinking process disabled, it outperforms its predecessor, 2.0 Flash, while delivering impressive results on complex tasks thanks to its “thinking” capabilities. In benchmarks such as LMArena, 2.5 Flash confidently holds its own against competing models – and does so at a significantly lower cost and with a smaller model size.
Particularly fascinating: the AI decides independently how intensively it needs to think. For simple questions such as translations, it works directly, while for complex mathematical problems or programming tasks, it exploits its full thinking potential.
Why it matters: This technology marks a decisive step toward truly adaptive AI systems that can flexibly adapt to a wide range of user needs. With the ability to control thought processes, Google is ushering in a new era of balance between AI performance and resource efficiency.

Graph of the Day

AI improves forecasts of ECB monetary policy decisions
A study by the German Institute for Economic Research (DIW Berlin) shows that AI-supported text analysis can increase the accuracy of European Central Bank (ECB) decisions from 70% to 80%. By analyzing the wording used in ECB communications, monetary policy signals can be identified more precisely. This marks a turning point, as AI is increasingly being integrated into the interpretation of monetary policy communication and could thus influence the responsiveness of markets and central banks
Virtue AI secures AI systems in the financial sector
The start-up Virtue AI has received US$30 million to develop a platform for securing AI systems. This solution addresses growing security concerns in the financial sector, which is increasingly relying on AI applications. The innovation represents a turning point, as it lays the foundation for trustworthy AI use in sensitive areas such as finance, thereby supporting the widespread implementation of AI technologies.
Amazon predicts falling AI costs thanks to new chips
In his letter to shareholders, Amazon CEO Andy Jassy predicts a significant decline in AI costs due to advances in chip technology, particularly the new Trainium2 chips. This development could represent a turning point by making AI technologies more accessible to companies and thus promoting the integration of AI into various business models.
