Liquid reports the 1.7B text model beats its 2.6B predecessor with 35% fewer parameters, scoring 38.42 vs 3.02 on WebArena-Verified. ## Key facts - Architecture: tri-hybrid mix of 13 gated short convolutions (kernel 7), 5 sliding-window attention layers (256-token window) and 6 global attention layers, with head-wise gated attention and partial RoPE; chosen by hardware-in-the-loop search over 14 device/backend combinations (phones, Raspberry Pi 5, laptops, CPUs, GPUs, Qualcomm Hexagon NPU) - Training: LFM3-1.7B-Base pre-trained on 22T tokens; the last 3.5T tokens are mid-training with more agentic traces and tool calls, extending context to 256K - Vendor numbers: LFM3-VL-2B (1.9B) raises the average over 62 vision benchmarks to 71.4 from 57.6 for LFM2.5-VL-3B, 'on par with Gemma 4 12B'; new 164M vision encoder uses 2.2x fewer FLOPs than Qwen3.5-2B's; audio time-to-first-token as low as 50 ms; LiquidCodec decodes speech ~87x real time on one Apple M4 Max CPU thread; d1-2B scores 75.5 vs 64.0 for d1-3B on ImajevBench - Robotics: Liquid adapted LFM3-VL-2B into orchestration, navigation and manipulation models for a robot arm and mobile navigation (demo video) - Licence: LFM Open License v1.0; Hugging Face lists LFM3-1.7B since Oct 23 (published Oct 27 with the blog), ~16k downloads and 436 likes by Oct 29 ## What happened Liquid AI moved its whole small-model line to one new backbone and shipped text, vision, audio, omni and decision variants at once, each small enough to fine-tune on one GPU and run on a phone or laptop. ## Why it matters Most frontier progress is in huge models; LFM3 is aimed at the opposite end, where agents run on-device. The benchmark gains are the vendor's own and await independent tests. ## Your AI and this story - GPT-6 Astra (training cutoff April 2026): 180 days after its cutoff - Claude Opus 5.5 (training cutoff June 2026): 119 days after its cutoff - Gemini 4 Hydrogen (training cutoff March 2026): 210 days after its cutoff - Grok 4.7 (training cutoff May 2026): 149 days after its cutoff ## Sources 1.
