16 GB VRAM16 TOOLS FIT THIS TIER

AI tools that run on 16 GB VRAM

Sixteen gigabytes reduces compromise for multi-component image graphs and expands quantized LLM and video options. Unified memory on Apple Silicon is not directly interchangeable with discrete VRAM: the operating system and application share the same pool, and backend support differs.

Capabilities

✓ WHAT YOU CAN RUN

  • LTX-Video and CogVideoX 5B locally
  • AnimateDiff with SDXL motion modules
  • EXL2 quantized LLMs (better throughput than GGUF)
  • Large diffusion checkpoints with documented memory optimizations
  • Many multi-component ComfyUI image workflows with useful headroom

✕ WHAT STAYS OUT OF REACH

  • HunyuanVideo 13B at sensible speeds
  • Large video variants at high precision without offload
  • 70B LLMs without partial CPU offload

VRAM tier ≠ universal guarantee

These are planning envelopes. Model variant, precision, resolution, frame count, context, cache, runtime, and offload can move the same workload across tiers. The guide shows how to validate a real ComfyUI graph before buying hardware.
