Google has announced the general availability of its Gemini 2.5 Flash and Gemini 2.5 Pro AI models, making them stable for production applications. This expansion of the Gemini 2.5 family also includes the unveiling of a preview for Gemini 2.5 Flash-Lite, positioned as the most cost-effective and rapid model in the series.
“We designed Gemini 2.5 to be a family of hybrid reasoning models that provide amazing performance, while also being at the Pareto Frontier of cost and speed. Today, we’re taking the next step with our 2.5 Pro and Flash models by releasing them as stable and generally available. And we’re bringing you 2.5 Flash-Lite in preview — our most cost-efficient and fastest 2.5 model yet,” the company announced in an official statement. The transition of Gemini 2.5 Flash and 2.5 Pro from preview to general availability follows a period of extensive feedback from developers and businesses. Companies like Snap, SmartBear, Spline, and Rooms have already integrated these models into their applications.
The newly unveiled Gemini 2.5 Flash-Lite marks the latest addition to Google’s AI offerings, designed for workloads where the focus is on speed and efficiency. This lightweight model is now available in preview, so developers can assess its capabilities and contribute feedback. Flash-Lite’s design, as per Google, prioritizes latency, delivering faster responses while consuming fewer compute resources. This makes it a viable option for large-scale applications where cost efficiency and rapid processing are major considerations. Despite its compact nature, Flash-Lite retains core functionalities of the Gemini 2.5 family, including support for a 1 million-token context window, enabling it to process extensive documents, conversations, and codebases. It also integrates with Google Search and code execution tools, processes multimodal inputs, and provides accurate responses across diverse tasks.
All models within the Gemini 2.5 series are built on a Mixture-of-Experts (MoE) architecture. This design allows the models to activate only specific neural networks relevant to a given prompt, optimizing hardware usage and contributing to lower inference costs. Furthermore, Gemini 2.5 models represent the first generation trained using Google’s internally developed TPUv5p AI chip, utilizing clusters equipped with new software for technical issue mitigation during training. With Gemini 2.5 Pro and Flash reaching general availability, they provide stable, production-ready models for complex tasks like advanced coding, intricate reasoning, and multimodal understanding, which can be useful to ensure reliability and consistent performance, while the different models (Pro for power, Flash for speed, Flash-Lite for extreme efficiency) allow for better optimization of resources based on specific needs.
Developers can access the stable versions of Gemini 2.5 Flash and Pro through Google AI Studio, Vertex AI, and the Gemini app. The preview of Gemini 2.5 Flash-Lite is available via Google AI Studio and Vertex AI. Custom versions of Flash and Flash-Lite have also been integrated into Google Search, extending their capabilities to various search-related AI features, where Google aims to employ the most suitable model for each query.
Pricing structures for the expanded Gemini 2.5 family reflect the differing capabilities and target use cases of each model. Gemini 2.5 Flash-Lite is set at $0.10 per 1 million input tokens (for text, images, or video) and $0.40 per 1 million output tokens, positioning it as the most economical entry point. Gemini 2.5 Flash costs $0.30 per million input tokens and $2.50 per million output tokens.
