LiquidAI: LFM2.5-1.2B-Thinking (free)

LiquidAI: LFM2.5-1.2B-Thinking (free) is a large language model API from Liquid AI, part of its LFM2.5-1.2B-Thinking (free) 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. The 33K-token context window — around 49 pages of text — comfortably handles long documents, multi-file code, or extended conversations. On Artificial Analysis's Intelligence Index it scores 3 (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.
