Model Card | Liquid AI LFM3-1.7B
LFM3-1.7B: released 2026-10-27, 1.73B parameters, 256K context, LFM Open License v1.0 (free commercial use under $10M annual revenue). A tri-hybrid architecture (13 short-convolution layers, 5 sliding-window attention, 6 global attention) cuts KV cache to about 27% of a standard transformer. It scores 38.42 on WebArena-Verified, beating both the predecessor LFM2.5-2.6B (3.02) and the 5x-larger Qwen3.5-9B (28.94), but still trails Qwen3.5-9B on long-context understanding (AA-LCR) and knowledge-heavy tasks (GPQA Diamond). Liquid AI's own model card says it isn't recommended for agentic coding or complex multi-step reasoning. Liquid Console API pricing: $0.08 input / $0.20 output per 1M tokens (cached input $0.02). The same release also ships VL, Audio, Omni, and two decision models sharing the same backbone.
