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: 42.6 tok/s decode · 4.5s TTFT (warm) · 107 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 MacBook Pro M4 Pro 24GB run Dolphin 2.9 8B?
Yes, MacBook Pro M4 Pro 24GB can run Dolphin 2.9 8B with a C grade (Runs well). Expected decode speed: 43.1 tok/s.
How much VRAM does Dolphin 2.9 8B need?
Dolphin 2.9 8B (8B parameters) requires approximately 10.3 GB of memory with Q4_K_M quantization.
What is the best quantization for Dolphin 2.9 8B?
The recommended quantization for Dolphin 2.9 8B is Q4_K_M, which balances quality and memory efficiency.
What speed will Dolphin 2.9 8B run at on MacBook Pro M4 Pro 24GB?
On MacBook Pro M4 Pro 24GB, Dolphin 2.9 8B achieves approximately 43.1 tokens per second decode speed with a time-to-first-token of 4494ms using Q4_K_M quantization.
Can MacBook Pro M4 Pro 24GB run Dolphin 2.9 8B for coding?
For coding workloads, Dolphin 2.9 8B on MacBook Pro M4 Pro 24GB receives a C grade with 43.1 tok/s and 33K context.
What context window can Dolphin 2.9 8B use on MacBook Pro M4 Pro 24GB?
On MacBook Pro M4 Pro 24GB, Dolphin 2.9 8B can safely use up to 33K tokens of context. The model's official context limit is 33K, but available memory constrains the safe maximum.
Is unified memory on MacBook Pro M4 Pro 24GB as fast as VRAM for Dolphin 2.9 8B?
Not always. MacBook Pro M4 Pro 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.
