FreeToken
FreeToken runs large mixture-of-experts language models on a personal computer by sharing the work across the GPU, system memory, and CPU.
It is the engine between downloaded model weights and the chat app or coding agent you want to use.
What it is
A runtime for models larger than GPU memory
A mixture-of-experts model activates only some of its expert weights for each token. FreeToken uses that pattern to keep some weights in RAM and bring in, or compute, the parts needed next.
Why it stands out
Memory can change jobs during a session
The project describes reallocating GPU memory between cached experts and conversation context while the engine is running, without restarting it or reloading the weights.
Availability
Desktop and command-line paths
The Apache-2.0 repository links Windows and Linux desktop downloads, a Python package, and source installation. The Python path has its own hardware and CUDA requirements.
Why it matters
What makes it useful
A model that exceeds your graphics card's memory may still be a candidate for this kind of setup. FreeToken's CPU-GPU execution gives you another route to explore before replacing the GPU; the available RAM and transfer bandwidth still constrain what is practical.
What to know
Where it fits
Start a model server, then point an OpenAI- or Anthropic-compatible client at its local address. A terminal chat interface is included. Coding-agent launch helpers can also configure clients to use that server.
Notable points
What stands out
Its context cache is designed for agent sessions where tool calls and thinking blocks change the conversation. The project describes saving checkpoints so these edits need not trigger the same context computation from the beginning.
Before using
What to review
The Python installation guide lists Linux x86_64, NVIDIA hardware, driver r580 or newer, Python 3.10 or newer, and a CUDA 13 toolkit for first-use kernel compilation.
Check the supported-model and backend guide before downloading weights. The model still needs storage and enough memory across the machine.
The runtime repository names Apache-2.0; the selected model has its own model card and current terms to follow.
The project's performance figures describe its reported setups. Compare the available backends on your actual machine with the model and prompt lengths you intend to use; fitting the weights does not establish a usable response speed.
The coding-agent launcher can write provider configuration and install a missing CLI. Its dry-run option shows the proposed changes first.
Check the original listing's documentation for current requirements, limitations, licensing and any relevant privacy or security considerations.
Reader fit
Who may find it relevant
For local-AI builders comfortable with model downloads, drivers, and runtime settings. The useful starting question is whether an explicitly supported MoE model fits the whole computer's resources, rather than the GPU alone.
Editorial note
Why LifeHubber lists it
Moving a missing expert from RAM to the GPU is not the only option: FreeToken's hybrid strategy overlaps fetching some experts with computing others on the CPU. This is a reason to consider it for a computer with useful CPU capacity alongside a memory-limited GPU, rather than treating every missing expert as a transfer the GPU must wait for.

What to explore next
Compare the engine with the model and hardware choices around it.
FreeToken changes how a large MoE model uses one machine. These next paths help compare a different low-memory method and the wider local setup before choosing a runtime.
