| Workload | Input | Output | Estimated cost |

| Product chat month | 500,000 | 125,000 | $0.112 |

Strengths
- ✓ $0.05 in / $0.70 out per million with open weights (LiquidAI/LFM2.5-24B-A2B)
- ✓ 24B total and 2.45B active parameters: an MoE built to be cheap to run, not to top a leaderboard
- ✓ Always reasons before answering and is positioned for agents that call tools
Limitations
- ! Text only — no images, files or audio
- ! 128,000-token context and an 8,192-token output ceiling
- ! Cheap enough that output pricing, not input, sets the bill: output costs 14x input here
