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: 15.2 tok/s decode · 12.7s TTFT (warm) · 38 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.

Frequently asked questions
Can Mac mini M2 24GB run DeepSeek LLM 7B?
Yes, Mac mini M2 24GB can run DeepSeek LLM 7B with a C grade (Tight fit). Expected decode speed: 15.2 tok/s.
How much VRAM does DeepSeek LLM 7B need?
DeepSeek LLM 7B (7B parameters) requires approximately 15.1 GB of memory with Q4_K_M quantization.
What is the best quantization for DeepSeek LLM 7B?
The recommended quantization for DeepSeek LLM 7B is Q4_K_M, which balances quality and memory efficiency.
What speed will DeepSeek LLM 7B run at on Mac mini M2 24GB?
On Mac mini M2 24GB, DeepSeek LLM 7B achieves approximately 15.2 tokens per second decode speed with a time-to-first-token of 12718ms using Q4_K_M quantization.
Can Mac mini M2 24GB run DeepSeek LLM 7B for coding?
For coding workloads, DeepSeek LLM 7B on Mac mini M2 24GB receives a C grade with 15.2 tok/s and 4K context.
What context window can DeepSeek LLM 7B use on Mac mini M2 24GB?
On Mac mini M2 24GB, DeepSeek LLM 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 Mac mini M2 24GB as fast as VRAM for DeepSeek LLM 7B?
Not always. Mac mini M2 24GB 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.
