Gemini 3.1 Flash-Lite is Google's lightweight language model in the Gemini 3 series, priced at $0.25 per million input tokens and $1.50 per million output tokens, designed for cost-sensitive and high-volume developer workloads. The model offers 2.5X faster response times and 45% higher output speed compared to its predecessor and has been deployed in applications including Google Cloud's Always-On Memory Agent for maintaining continuous context in AI systems. It competes in the price-performance segment against models like OpenAI's GPT-5.6 Luna and serves as a baseline for performance comparisons in benchmarks like computer use tasks.
