Google Unveils Gemini 2.5 Flash Model with Enhanced Features
Last week during the highly anticipated Cloud Next event, Google made an exciting announcement regarding the upcoming rollout of the Gemini 2.5 Flash model. This new iteration promises substantial advancements and is now available for preview through the Gemini API in both Google AI Studio and Vertex AI environments. Gemini users can conveniently access this model using the model picker, which integrates seamlessly with Canvas, enhancing the refinement process for documents and code.
Improvements Over Its Predecessor
Building on the foundation laid by its predecessor, Gemini 2.0 Flash, the 2.5 version introduces notable enhancements in reasoning capabilities while maintaining affordability and minimizing latency. According to Google, this new model is designed to deliver an outstanding performance-to-cost ratio. Here are the pricing details:
- $0.15 for every 1 million input tokens
- $0.60 for each million output tokens without reasoning
- $3.50 for every million output tokens with reasoning
This is an early version of 2.5 Flash, but it already shows huge gains over 2.0 Flash. You can fully turn off thinking if needed and use this model as a drop-in replacement for 2.0 Flash. It’s available across the Gemini API, AI Studio, Vertex, and the Gemini app!

Introducing Hybrid Reasoning Capabilities
The Gemini 2.5 Flash model marks a significant milestone as Google’s first fully hybrid reasoning model, enabling developers to toggle reasoning functionalities on or off. This flexibility empowers developers to optimize their applications, tailoring the trade-offs among quality, cost, and response latency according to specific project needs.
Comparative Performance Insights
As illustrated in the accompanying benchmark table, the Gemini 2.5 Flash model competes effectively against leading models from Anthropic and Grok, despite its lower cost structure. Although OpenAI’s recently launched o4-mini shows superior performance compared to the Gemini 2.5 Flash preview, it comes at a significantly higher price point, highlighting the competitiveness of Google’s offering in the current landscape.
