Recently, Google made significant updates to its Gemini series of large language models (LLMs), especially Gemini 2.5 Flash and Flash Lite, emphasizing improvements in speed and efficiency. These improvements are continuously being made between major releases, demonstrating Google's commitment to continuous progress in the AI field.
According to evaluations by third-party analysis firm Artificial Analysis, Gemini 2.5 Flash Lite has become the "fastest proprietary model" on their website, with an output speed of 887 tokens per second, a 40% improvement over the previous version. Although it still lags behind the new K2Think open-source model launched by MBZUAI and G42AI, which outputs 2,000 tokens per second, the speed of Gemini 2.5 Flash Lite remains impressive.
These two new models have seen significant improvements in output quality and cost efficiency, especially in token usage and response speed. Gemini 2.5 Flash performs well in multi-step and autonomous workflow processing, achieving a score of 54% on the SWE-Bench Verified benchmark. Flash Lite has also improved in following instructions and multimodal capabilities, reducing output tokens by 50%, which lowers deployment costs in high-volume applications.
In independent benchmark tests, the performance of Gemini 2.5 Flash and Flash Lite was further confirmed, with noticeable improvements in scores across multiple tests. To make it easier for developers to use, Google also introduced new aliases to facilitate integration with the latest versions of the models.
In addition to the LLM updates, Google also enhanced Gemini Live, a real-time audio model designed specifically for voice applications. The new version improved the reliability of function calls and the ability to handle natural conversations, allowing developers to build more responsive voice assistants that can better interact with users in dynamic environments. Users can directly use the updated Gemini Live model through the new preview version.
Google's recent update not only improved the performance and usability of the models but also provided developers with more flexibility. In the future, Google plans to release more updates in the Gemini series to meet the evolving needs of developers.
