Check before purchasing
The available memory is small, making it difficult to use models larger than 20B and long contexts together.
What tasks is it suitable for?
| task | determination | reason |
|---|---|---|
| Document/Summary | fit | Fits short documents and 8B to 12B models. |
| coding assistant | conditional | Small models are possible, but large storage contexts are tight. |
| Create image | conditional | It focuses on lightweight models and has fewer choices than the NVIDIA ecosystem. |
Configuration Selection Criteria
The first bottleneck encountered
The first limitation is the context length, as we need to fit the model and KV cache together in 13GB.
Recommended purchase setup
M4 · Integrated memory 16GB · SSD 512GB or more
Criteria for spending more money
It is enough if you only use 8B~12B. If you are thinking of 27B, 24GB or more is better from the beginning.
