Gemini 2.0 Flash LitevsGemini 2.5 Pro

Gemini 2.0 Flash Lite is Google's most affordable model, designed for extremely high-volume applications where cost is the primary concern. At just $0.075 per million input tokens, it's one of the cheapest AI models available from a major provider. Despite its low price, it supports a 1 million token context window and handles basic tasks competently. Ideal for classification, routing, content filtering, and other high-throughput tasks.

Gemini 2.5 Pro is Google DeepMind's most capable AI model, featuring an industry-leading 1 million token context window that can process entire books, codebases, or hours of video in a single request. Built with native multimodal capabilities, it understands text, images, audio, and video natively rather than through separate encoders. The model demonstrates exceptional performance on coding benchmarks, mathematical reasoning, and multi-step planning tasks. Its massive context window makes it uniquely suited for tasks involving large document analysis, repository-scale code understanding, and long video comprehension. Gemini 2.5 Pro also features built-in 'thinking' capabilities similar to reasoning models, allowing it to tackle complex problems with improved accuracy. Available through Google AI Studio and Vertex AI.
