Summary
Connects Claude to Apple's on-device 3B parameter model that ships with Apple Intelligence on M-series Macs running macOS 26+. Exposes five tools: fm_generate for text completion, fm_summarize for bullet points, fm_classify for categorization, fm_extract for structured data, and fm_status to check availability. Everything runs locally on the Neural Engine with sub-second to few-second latency and zero API costs. Reach for this when you want fast, private inference for simple tasks like quick classification or extraction where Claude would be overkill, or when you're doing privacy-sensitive work that needs to stay on-device. Requires Apple Silicon and Apple Intelligence enabled in System Settings.

fm_generate | Free-form text generation | ~1s |
fm_summarize | Summarize text into bullet points | ~4s |
fm_classify | Classify text into categories | ~2s |
fm_extract | Extract structured data from text | ~3s |
fm_status | Check model availability | instant |
Why Use This?
- Free: No API keys, no tokens, no cloud costs
- Private: All inference on-device, no data leaves your Mac
- Fast: Neural Engine optimized, ~1s for generation
- Complementary: Use alongside Claude for tasks where on-device speed matters
