Key points
- RIPL is a low-latency engine that serves Liquid Foundation Models (LFMs) inside a live request path.
- Performance: 5.6 to 28.4x lower p95 latency than Qwen3.5 on vLLM, per Liquid’s own tests.
- Liquid AI describes RIPL as optimizing the full path, from request arrival to completed response.
- In several workloads, Liquid AI plots the same model, LFM2.5-350M, on vLLM and on RIPL.
