How to run it
I can set this up end to end: pick the model size, deploy it on your server and connect it to your systems. Quantization compresses a model so it takes less video memory and runs on more modest hardware. Answers change slightly, so quality is checked on your own examples.

With conditions. License: Moondream 2: Apache 2.0; Moondream 3: Moondream Model License (commercial use in your own products is allowed; you cannot sell access to the model itself as a cloud service). Restrictions vary — region, company revenue, attribution requirements. Have a lawyer check the terms before a commercial launch.
What hardware does Moondream need?
At minimum: Laptop or regular PC, up to 8 GB of VRAM — smaller versions. Some versions also run on an ordinary CPU, without a GPU. You can calculate the exact VRAM for your model size and context in the hardware calculator.
Does Moondream support Russian?
No. The model card lists its languages and Russian is not among them.
