Local AI Runtime

Learn how to tune RenamerX local AI runtime settings for memory usage, GPU policy, parallel slots, context size, and image detail.

Local AI Runtime

RenamerX uses a local AI runtime, so runtime settings influence quality, speed, and resource efficiency.

Most users should leave the defaults alone. This page is for the cases where you need to tune performance or stability.

What RenamerX installs locally

After first launch, RenamerX prepares the local resources needed for on-device AI processing and media analysis, including:

  • A local AI processing engine
  • Model resources for document and image understanding
  • Media-analysis components used by video workflows

Runtime settings in Preferences

Available runtime controls include:

  • Performance mode
  • Context size
  • GPU policy
  • Parallel slots
  • Image detail

Most of these changes are intended to take effect on the next app start, so avoid expecting every runtime adjustment to reconfigure the active session immediately.

Performance mode

RenamerX includes three performance profiles:

  • lowMemory
  • balanced
  • highPerformance

These profiles change multiple settings together.

Low Memory

Works well on smaller machines or when you want a lower resource footprint.

Balanced

The default profile. This is the right starting point for most users.

High Performance

Best when you have stronger hardware and want more throughput. It uses more aggressive runtime settings.

Context size

Available context sizes are:

  • 4096
  • 8192
  • 12288

Higher context can help with more complex extraction, but it also increases memory pressure.

GPU policy

Available GPU policies are:

  • auto
  • aggressive
  • cpuOnly

Use:

  • auto for most systems
  • aggressive when you know your machine handles GPU inference well
  • cpuOnly when GPU inference causes instability or you want predictable CPU-only behavior

Parallel slots

Available parallel settings are:

  • 1 slot
  • 2 slots

Higher parallelism can improve throughput, but it can also increase RAM and GPU pressure.

Image detail

Available image-detail levels are:

  • fast
  • balanced
  • detailed

Use detailed when visual nuance matters more than throughput. Use fast when you are optimizing for speed.

If the app feels heavy

  • Switch to Low Memory
  • Reduce context size
  • Use CPU Only
  • Keep parallel slots at 1

If image and video naming feels weak

  • Keep Balanced or High Performance
  • Increase image detail
  • Make sure local resources finished downloading completely

If you are processing mixed media all day

  • Stay on Balanced first
  • Increase only one setting at a time
  • Measure stability before enabling more parallel work

A practical rule

Do not tune everything at once. Change one runtime setting, run a real batch, and judge the result with your own files.
