FreeToken, a new Mixture of Experts (MoE) model serving engine, has been released and compared against established tools like Ollama and llama.cpp. Unlike Ollama and llama.cpp, which split model weights between GPU and CPU at load time, FreeToken employs a dynamic approach. It keeps all experts in CPU RAM and uses the GPU's spare memory as an LRU cache for recently used experts, intelligently deciding whether to pull weights over PCIe or compute them on the CPU based on real-time bandwidth measurements.
