Model Card

LFM2.5-24B-A2B is a sparse Mixture-of-Experts reasoning model from Liquid AI with 24B total parameters and about 2.45B active per token. It has a 131K context window and always produces a reasoning trace before answering.

It is built for agents and tool calling. Liquid AI reports IFEval 96.75, IFBench 74.69, BFCLv4 65.01, ToolSandbox 80.71 and SWE-Bench Verified 51.00. It scores higher than Qwen3.6-35B-A3B and Gemma-4-26B-A4B-it on most agentic and instruction-following tests, but trails Qwen3.6-35B-A3B on coding (SWE-Bench Verified 66.20) and GPQA Diamond (83.69 vs. 74.42).

It suits developers building tool-calling agents, especially with retrieval or web search. Liquid AI advises against using it alone for knowledge-heavy tasks or where direct, non-reasoning replies are needed.
