Google: Gemma 3n 4B (free)

Google: Gemma 3n 4B (free) is a large language model API from Google, part of its Gemma 3n model family. It is currently routed free of charge on OpenRouter, which makes it well suited to prototyping and high-volume experimentation where per-token cost would otherwise dominate. Its 8K-token context window is on the compact side — roughly 12 pages of text — best suited to short prompts and chat-style turns. On Artificial Analysis's Intelligence Index it scores 5 (F 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.
