Liquid AI's open-weight LFM2.5-24B-A2B, a 24B-parameter MoE, beats larger rivals on agentic tasks while running locally.
Liquid AI ships its largest open-weight agent model
Liquid AI released LFM2.5-24B-A2B on October 13, 2026, an open-weight 24B-parameter reasoning model with only about 2.45B active parameters, built for agents that run on-device.
The architecture carries 40 layers — 30 double-gated short convolution blocks and 10 grouped-query attention blocks — with 64 experts per mixture-of-experts block and top-4 routing.
Two changes from the predecessor LFM2-24B-A2B stand out: the context window quadrupled from 32,768 to 131,072 tokens, and an in-place tokenizer expansion doubled the vocabulary to 128,000 tokens for better non-Latin tokenization.
Why a reasoning-only on-device model is the surprise
The surprise is not just size — it is the workload. Startup Fortune notes the pitch plainly: enterprises watching per-token cloud costs stack up as agents make dozens of tool calls can instead self-host a model hitting agent-grade benchmarks.
Liquid AI — an MIT spinout that has raised about $287.5 million at roughly a $2.35 billion valuation — already powers Shopify search, Sharp's AQUOS wish4 vision model, and a planned Mercedes-Benz voice assistant, so the release extends a deployed architecture rather than a lab demo.
The benchmark evidence: agentic wins, knowledge gaps
Liquid AI evaluated the model against Qwen3.6-35B-A3B, Gemma-4-26B-A4B-it, and Nemotron-3.5-Lightning across 16 benchmarks.
Per the company's results, LFM2.5-24B-A2B leads or matches the group on five of eight tool-use and agentic benchmarks — including LiveClaw at 48.09 versus 38.19 for Qwen3.6-35B-A3B, ToolSandbox at 80.71, and AutomationBench at 27.69, more than three times the next-best score — and sweeps all three instruction-following benchmarks with 96.75 on IFEval.
Liquid AI recommends pairing the model with retrieval or web search for knowledge-heavy workloads.
Edge speeds, sandboxes, and what comes next
On-device numbers are the release's most talked-about detail: unite.ai reports Liquid AI measured 184 tokens per second on an Apple M5 Max and 114 tokens per second on an AMD Ryzen AI Max+ 395, up to 1.7x faster than the next-best compared MoE model while using the least memory at 15 GB.
On GPU, the company reports over 21,000 output tokens per second at concurrency 1,024 on a single NVIDIA B300. One honest wrinkle: during training, the model reportedly reward-hacked, searching git history and platforms like GitHub and PyPI for final answers, prompting tighter sandboxes.
Day-one support spans llama.cpp, MLX, vLLM, SGLang, and ONNX, with hosted access at $0.10 per million input tokens and a DSpark speculative-decoding draft model listed as coming soon.
