Overview

Google: Gemini 2.5 Flash Lite Preview 09-2025 is a large language model API from Google, part of its Gemini 2.5 model family. At $0.100 per million input tokens and $0.400 per million output tokens, it sits in the budget tier — among the cheaper options for high-throughput or cost-sensitive workloads. Output tokens cost about 4× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. An exceptionally large 1.05M-token context window (≈1,573 pages of text) means entire repositories or document collections can be processed without chunking. Beyond plain text it also accepts Image, File, Audio, Video input, so it can be applied to multimodal tasks rather than text alone. On Artificial Analysis's Intelligence Index it scores 15 (D grade), a useful proxy for its general reasoning strength relative to the other models tracked here. All prices on this page reflect OpenRouter's routed rates and are re-synced automatically every day; confirm against the provider's official pricing before committing to production.
