Kaliko Workspace
Local AI on the PC you already have. A 4 GB graphics card is enough. Your models, your data, and your rules for how they run.

Figures are from Kaliko's own tests on a 4 GB card.
System intelligence
Kaliko reads your GPU, your RAM and every model's real size, including the memory its context window needs. Then it tells you plainly how each model will run. Nothing is loaded to find out.
The Spark for the lower end
NVIDIA built RTX Spark so a personal AI computer could sit on a desk. Kaliko brings the same idea to hardware people already own: local models that are tuned, checked and kept on track until a small GPU is genuinely useful.

Model fit checks, right-sized context windows, and answers checked against their sources so small models stay accurate.

Privacy and control
Models, chats and files stay on your computer. Nothing leaves unless you connect a cloud provider yourself.
Choose the model for every chat and the runtime underneath it, and set how much context it gets.
Anything that sends, deletes or changes something stops and asks first. Every change can be undone.
Every turn, traced
Each request is planned, run and verified by Kaliko's runtime. Open any turn to read its full trace, from the goal to the final check.
