FAQ
Can the Apple M2 Pro (16GB) run LFM2.5-2.6B (free)?
Yes. The Apple M2 Pro (16GB)'s 16.0GB of unified memory is enough to run LFM2.5-2.6B (free) at fp16 quantization (6.2GB required).
What's the best quantization to use?
fp16 is the highest-precision quantization that fits in your 16.0GB. It uses about 6.2GB of memory and 7.7GB recommended for comfortable inference.
What if I need more headroom for context length?
KV cache memory grows with context length. The numbers above assume a baseline 2K-4K context. For long-context use (32K+), add another 2-6GB depending on the model architecture.
