LiquidAI: LFM2.5-1.2B-Thinking (free)
Analysis Summary
LiquidAI’s LFM2.5-1.2B-Thinking is a free text model with a 32K context window and stated tool use and function calling. Its measured intelligence index is 5.2. The supplied GPQA, HLE, SciCode, instruction-following, and tau2 results are also limited, so the data does not support using it for complex reasoning or reliable autonomous workflows.
The tool interface gives it a possible role in simple, tightly constrained automations, while the small context and low measured capability make it a poor fit for long documents or high-stakes decisions. Outputs should be verified, especially when a tool action could affect client systems or records.
Free access is valuable for experimentation and low-risk workloads. Treat it as a lightweight option rather than a general assistant, and confirm that the cost saving outweighs added review and correction effort.
