Frequently Asked Questions
What is Gemma 3 4B good for?
Local and edge deployments taking text and images. Open weights under the Gemma Terms of Use, small enough for a single consumer GPU.
When is Gemma 3 4B not a good fit?
Video or audio input, and structured output. The Gemma Terms of Use are a custom license rather than Apache 2.0, and the Gemma 4 family knows more recent events.
What is the cheapest way to run Gemma 3 4B?
No provider we track hosts it; self-hosting on the cheapest rental that fits (1x GTX 1660 Super, $0.06 per hour) costs about $43 a month.
Can I self-host Gemma 3 4B?
Yes. The weights are released under the Gemma Terms of Use. At 4-bit it needs about 5 GB of GPU memory, which starts at roughly $43 a month on the cheapest rental that fits.
