Unlock datacenter-class intelligence on the hardware you already own — Run 290B+ frontier MoE models locally on your gaming PC at blistering interactive speeds.
About
FreeToken is an edge-native Mixture-of-Experts (MoE) serving engine designed for running frontier-scale open-weight models on personal and consumer
hardware. It treats heterogeneous edge resources—GPUs, CPUs, host memory, and interconnects—as a unified, elastic inference platform. Its core
features include:
- Fast Edge-Native Runtime: Provides efficient MoE serving with bandwidth-adaptive CPU–GPU co-execution ($q^\star$ policy), full-layer
double-buffered prefill streaming, global LRU expert caching, graph-compatible execution, and the FTW fast weight format. - **Semantic-Aware
Caching**: Features semantic anchor checkpoints for recurrent state and KV caches, allowing agentic context edits (e.g., tool calls, thinking blocks)
to avoid redundant context recomputation. - Elastic Memory Management: Supports dynamic, runtime VRAM re-allocation between expert caches and KV
memory without engine restarts or weight reloading. - Broad MoE & Ecosystem Support: Supports frontier open-weight MoE models (e.g.,
DeepSeek-V4-Flash, Qwen3.6-35B-A3B, GLM-5.2) across various parameter scales and quantization formats (e.g., MXFP4, NVFP4, FP8, BF16), with
Anthropic/OpenAI-compatible APIs for seamless integration with real-world coding and tool-calling agents (e.g., Codex, Claude Code, OpenCode,
OpenClaw, DeepSeek Harness). - Diverse Consumer Hardware: Scales across consumer laptops, gaming desktops, and workstation GPUs, with native
support for NVIDIA RTX 30, RTX 40, and RTX 50 series GPUs.
Getting Started
Desktop app
Download FreeToken for Windows or Linux at flashml.ai. It sets the engine up for you and gives you a GUI for running models, chatting, and tuning the engine.
CLI
Install FreeToken with uv (recommended) or pip:
uv pip install "freetoken[accel]"
Or build from source:
git clone https://github.com/FlashML-org/FreeToken.git && cd FreeToken
uv venv && source .venv/bin/activate
uv pip install -e ".[accel]"
