Google launches Gemini 3.1 Flash Lite model, priced lower

Investing.com - Google announced the launch of Gemini 3.1 Flash Lite on Tuesday, a new AI model that the company claims is the fastest and most cost-effective product in the Gemini 3 series. The model is currently available as a preview for developers via the Gemini API in Google AI Studio and is open to enterprise users through Vertex AI.

The pricing for the model is $0.25 per 1 million input tokens and $1.50 per 1 million output tokens. Google states that, based on Artificial Analysis benchmarks, Gemini 3.1 Flash Lite outperforms its predecessor, 2.5 Flash, generating the first response token 2.5 times faster and increasing output speed by 45%.

Gemini 3.1 Flash Lite scored 1432 Elo points on the Arena.ai leaderboard, achieved 86.9% on the GPQA Diamond test, and 76.8% on the MMMU Pro test. Google says the model surpasses earlier, larger Gemini models, including 2.5 Flash, in reasoning and multimodal understanding benchmarks.

The model features dynamic thinking capabilities, allowing developers to adjust how the model handles specific tasks. Google explains that this feature is designed for managing high-frequency workloads such as bulk translation and content moderation, as well as more complex tasks like generating user interfaces and creating simulations.

Companies including Latitude, Cartwheel, and Whering are using Gemini 3.1 Flash Lite. Early testers report that the model’s accuracy in handling complex inputs rivals larger models while maintaining adherence to instructions.
