FastVLM: Apple's Extremely Fast Vision Language Model
Runs directly on iPhone, first token output up to 85x faster!
How Does FastVLM Work?
Image Understanding
Token Conversion
Language Generation
FastVLM efficiently understands image content, converts it into compact tokens, and then uses these tokens to quickly generate accurate text descriptions or answers for real-time AI applications.
Why Choose FastVLM? Core Advantages
Extreme Speed Performance
Astonishing first token output speed! FastVLM-0.5B is 85x faster than LLaVA-OneVision. FastVLM-7B (with Qwen2) is 7.9x faster than Cambrian-1-8B (at similar accuracy).
Compact & Efficient Design
Small model size, easier deployment. FastVLM-0.5B is 3.4x smaller than LLaVA-OneVision. Ideal for on-device use like iPhone, iPad, Mac.
On-Device AI Intelligence
No cloud dependency, runs directly on your Apple device, protecting privacy and responding faster.
Perfectly adapted to the iOS/Mac ecosystem, empowering edge AI applications.
