Gemini 2.5 Flash Lite

Gemini 2.5 Flash-Lite is Google DeepMind's fastest and lowest-cost model in the stable Gemini 2.5 family, priced at $0.10/1M input and $0.40/1M output tokens. It keeps core Gemini 2.5 capabilities including a 1M-token context window, multimodal input, optional thinking budgets and tool connections like Google Search grounding and code execution. It is tuned for very low latency, running faster than 2.0 Flash and 2.0 Flash-Lite on a broad sample of prompts. Ideal for high-volume classification, translation, intelligent routing and simple data extraction where speed and budget are the primary constraints.
