RIPL
A real-time inference engine introduced by Liquid AI, designed specifically for the LFM series of small models. It focuses on reducing p95 tail latency and optimizing real-time interactive scenarios.
Timeline (last 90 days)
Official data shows that on a single B200, LFM2.5-1.2B's p95 latency on RIPL is 14.4 to 28.4 times lower than Qwen3.5-0.8B's on vLLM.
RIPL is a pure software engine that can run on existing GPUs, with a low deployment barrier.
RIPL currently only serves the LFM series, and its range of model choices is far smaller than the open model library supported by vLLM.
The aforementioned 14.4–28.4x p95 latency advantage cannot be simply attributed to the engine itself; model architecture, quantization strategy, and KV Cache management may all have contributed to the difference.
RIPL has tailored batch size, operator fusion, and memory layout to the LFM structure, which is where specialized engines easily achieve multiplicative advantages.
RIPL is similar in approach to Groq LPU and Cerebras wafer-scale—all are software-hardware co-design—but the difference is that RIPL is a pure software engine, with a much lower deployment barrier.
