Direct answer

The fast answer for Phi-3 Mini 4K Instruct

Phi-3 Mini 4K Instruct usually starts around 3-4 GB in INT4, 5-6 GB in INT8, and 8-10 GB in FP16. A safe production starting point is T4 16GB or any healthy 8GB to 16GB route.

Quick answer

Phi-3 Mini 4K Instruct fits most cleanly when you start from VRAM, not brand names.

Phi-3 Mini 4K Instruct usually needs about 3-4 GB in INT4, 5-6 GB in INT8, and 8-10 GB in FP16. A safe starting route is T4 16GB or any healthy 8GB to 16GB route.

For Phi-3 Mini 4K Instruct, the route decision starts with memory fit. The model usually needs about 3-4 GB in INT4, 5-6 GB in INT8, and 8-10 GB in FP16 before you add runtime headroom.

  • Safe starting GPU: T4 16GB or any healthy 8GB to 16GB route
  • Best general production routes: T4 16GB, L4 24GB, RTX 4060 Ti 16GB
  • Add headroom for runtime behavior instead of treating the model size as the whole answer.

VRAM table

Phi-3 Mini 4K Instruct memory and route profile

Phi-3 Mini 4K Instruct is primarily used for lightweight assistant and task inference on cheaper gpu routes. Most teams start with the quickest safe answer for memory fit, then compare which production routes make sense.

The ranges on this page are practical starting points for planning. Actual deployment requirements still depend on runtime overhead, batching, and the execution framework.

Execution notes

What changes the route in production

A memory-fit answer is only useful if the route is healthy. Pages like this should explain that fit, latency, and route quality all matter once the model goes live.

For Phi-3 Mini 4K Instruct, the most relevant follow-up pages are the cost page and the run-without-GPU page because those are the next practical questions most teams ask.

  • Low-cost assistants
  • Workflow automation
  • Rapid prototyping with open models

FAQ

Frequently asked

What GPU do I need for Phi-3 Mini 4K Instruct?

A safe starting answer is T4 16GB or any healthy 8GB to 16GB route. Lighter quantized routes can use less memory, but that is the clean default most teams need first.

Can Phi-3 Mini 4K Instruct run on a consumer GPU?

In many cases yes, especially with quantization. The safer answer still depends on the exact precision, runtime overhead, and traffic shape you expect in production.

Why should this page link to pricing and run-without-GPU pages?

Because the next user question after requirements is usually either cost or whether the model can be run remotely without buying hardware directly.
