Small & Fast LiquidAI Models

Quick answer · Updated June 2026

The small, fast LiquidAI model is LFM2.5-1.2B-Thinking (free) — the efficient tier at 106 tokens/sec and Free per million input tokens. It trades a few points of raw intelligence for speed and cost, the right call for high-volume, latency-sensitive work. LFM2.5-1.2B-Instruct (free) (66 t/s) and LFM2-24B-A2B (57 t/s) round out the top three.
