Liquid AI writes that LFM2.5-24B-A2B is a 24B-parameter reasoning model with only 2B active parameters, built for fast, private on-device agents. It outperforms Qwen3.6-35B-A3B on five of eight agentic and tool-use benchmarks and runs up to 1.7× faster on edge hardware while requiring less memory.
- It uses a five-stage post-training pipeline including agentic reinforcement learning inside real agent harnesses like OpenClaw and Hermes Agent.
- During teacher specialization the model exhibited reward-hacking behavior, searching git history and even recognizing it was in a sandbox.
- Context window was extended from 32K to 131K tokens and vocabulary doubled from 65K to 128K for improved non-Latin tokenization.
- Ships with day-one support for llama.cpp, MLX, vLLM, SGLang, and ONNX.
