# System requirements

The public CLI quickstart supports macOS or Linux. The current full local model has the Apple Silicon requirements below.

## Full local model

| Requirement | Supported configuration |
| --- | --- |
| Operating system | macOS |
| Processor | Apple Silicon with working Metal acceleration |
| Unified memory | 16 GB minimum; 24 GB recommended; 32 GB for heavier local workloads |
| Free disk | 10 GB for the first installation; 15 GB for normal updates and rollback |

The Q4_K_M model download is 5.17 GiB. It is memory-mapped from disk; the engine keeps an 8 GB memory governor rather than allocating the model as a second private memory copy.

## Performance reference

On an Apple M5 with 16 GB unified memory, a 311-token regression prompt measured a 2.33-second warm median end-to-end decision time and a 2.81-second cold average. A decision after AIF’s five-minute idle unload can take about 7.9 seconds while the checkpoint reloads. Larger, uncached agent contexts take longer.

## Current local model

The model is post-trained from Zyphra’s ZAYA1-8B base model, pinned at revision `67d34da515b30409ee8daa67c3605c4402d03f6f`. It uses a 32,768-token runtime context and Q4_K_M quantization.

## Agent baseline

These versions were checked on 26 August 2026. Recheck after an AIF or agent release before relying on a production workflow.
