1st promptCold start — includes initialization
>What is local AI inference?
Local AI inference means running an AI language model directly on your own hardware — your laptop, desktop, or server — instead of sending requests to a remote cloud API.

When you run inference locally the model weights are loaded into your GPU or unified memory. Each token you generate requires reading those weights from memory, so memory bandwidth is the main bottleneck for decode speed.

Key benefits of running locally:
  - Full privacy: your prompts never leave your machine
  - No per-token cost or rate limits
  - Works offline once the model is downloaded
  - Latency depends only on your hardware
2nd promptWarm — model ready, no init overhead
>How much VRAM do I need?
It depends on the model size and quantization level. A rough rule of thumb:

  Model size     Q4 (4-bit)    Q8 (8-bit)    FP16
  7B params      ~4.3 GB       ~7.5 GB       ~14 GB
  13B params     ~7.9 GB       ~13.9 GB      ~26 GB
  70B params     ~42.7 GB      ~74.9 GB      ~140 GB

Most people use 4-bit quantization (Q4_K_M) which gives 90-95% of full quality at a fraction of the memory. A 24 GB GPU can comfortably run most 7B-13B models.
Estimated: 27.6 tok/s decode · 7.0s TTFT (warm) · 69 tok/s prefill

What limits this setup

This setup is broadly balanced for this model.

Shared-memory contention still exists

The OS, browser, and inference runtime all compete for the same physical memory pool, so real-world headroom is less forgiving than raw capacity suggests.

How much VRAM does OLMo 2 7B need?

OLMo 2 7B (7B parameters) requires approximately 9.1 GB of memory with Q4_K_M quantization.

What is the best quantization for OLMo 2 7B?

The recommended quantization for OLMo 2 7B is Q4_K_M, which balances quality and memory efficiency.

What speed will OLMo 2 7B run at on MacBook Pro M3 Pro 18GB?

On MacBook Pro M3 Pro 18GB, OLMo 2 7B achieves approximately 27.6 tokens per second decode speed with a time-to-first-token of 7023ms using Q4_K_M quantization.

Can MacBook Pro M3 Pro 18GB run OLMo 2 7B for coding?

For coding workloads, OLMo 2 7B on MacBook Pro M3 Pro 18GB receives a A grade with 27.6 tok/s and 4K context.

What context window can OLMo 2 7B use on MacBook Pro M3 Pro 18GB?

On MacBook Pro M3 Pro 18GB, OLMo 2 7B can safely use up to 4K tokens of context. The model's official context limit is 4K, but available memory constrains the safe maximum.

Is unified memory on MacBook Pro M3 Pro 18GB as fast as VRAM for OLMo 2 7B?

Not always. MacBook Pro M3 Pro 18GB can often fit larger models thanks to unified memory, but a discrete GPU with dedicated high-bandwidth VRAM may still decode faster once the model fits. For this combination, the important distinction is capacity versus sustained throughput.
