Google has released Gemini 2.5 Flash, a new large language model featuring controllable reasoning capabilities. Building upon the popular 2.0 Flash, it significantly improves reasoning while prioritizing speed and cost-effectiveness. Developers can adjust a 'thinking budget' to balance quality, cost, and latency. The model automatically adjusts its thinking process based on prompt complexity, offering modes ranging from no thinking to intensive reasoning. Gemini 2.5 Flash excels on LMArena's Hard Prompts, boasting a superior price-to-performance ratio, making it one of the most cost-effective thinking models available.
