AK XZ Axis so called XY testing for any type of KSampler: ComfyUI AK XZ Axis

---

ComfyUI-AK-XZ-Axis

A set of nodes for XY-style testing of parameters such as seed, steps, cfg, denoise, prompts, and LoRAs.

The main advantage of this pack is that it does not require a custom KSampler and works with any KSampler, including the default ComfyUI KSampler.

---

Why XZ and not XY?

When working with a standard KSampler, you cannot build a true two-dimensional XY grid in the classical sense.

In practice, you can only iterate along one axis (X), and optionally inject a second varying parameter inside that iteration. Honestly, I’m not even sure who really needs a full XY grid and in what scenario — but technically, this limitation exists.

That second parameter is what I call Z.

So instead of XY, this system operates as X + Z.

Demo Workflows

All required demo workflows are located in: /workflows/ folder

---

AK XZ Axis Plot

The main visualization node that creates the final "plot".

In reality, this node:

• Adds clean, readable headers to incoming images
• Can output:
  • Images one by one, or
  • All images merged into a single image

Inputs

• Images — images coming after the KSampler
• xz_config — must be connected to any Range or Batch node from this pack

Important behavior

If only one image is received, the node does nothing:

• No headers
• No processing
• Just passes the image through

This is intentional and allows you to disable XZ testing instantly without removing the node from your workflow.

AK XZ Range Int

A universal node for any integer parameter, such as:

• steps
• seed

Outputs

• Array of integers — connect this directly to the corresponding KSampler widget
• xz_config — connect to AKXZAxisPlot or another XZ node to enable Z-direction testing

Notes

The node is mostly self-explanatory.
There is an additional boolean option:

• steps_define_end — allows you to define only start and steps instead of manually calculating the end value.

---

AK XZ Range Float

Same logic as AK XZ Range Int, but for float parameters, such as:

• cfg
• denoise

Outputs and usage are identical, just with float values.

---

AK XZ Batch Prompts

A node for prompt testing.

• Supports up to 10 different prompts
• Inputs are simple:
  • positive — TEXT
  • negative — TEXT

Important: These are raw text inputs.
The node performs CLIP encoding internally.

Dynamic inputs

Additional prompt slots appear only when a PAIR is filled, meaning:

• Both positive and
• negative must be connected

Typical usage

Usually, you:

• Use the same negative prompt
• Test multiple positive prompts

Outputs

• Two arrays:
  • positive
  • negative

Both must be connected to the corresponding inputs of the KSampler.

• xz_config — connect to AKXZAxisPlot or another XZ node to enable Z-direction testing

---

AK XZ Batch Loras

Allows testing of multiple LoRAs.

Inputs

Each entry is a PAIR:

• model
• conditioning

You:

1. Load a LoRA
2. Encode your positive prompt manually
3. Feed both into this node

Repeat this for each LoRA you want to test.

Why no negative?

Negative conditioning is intentionally not supported here to avoid:

• Overcomplication
• Node overload

Just connect your negative conditioning directly to the KSampler.

Outputs

• models — array of models
• conditionings — array of positive conditionings

Both must be connected to the corresponding KSampler inputs.

• xz_config — connect to AKXZAxisPlot or another XZ node to enable Z-direction testing

Summary

• Works with any KSampler
• No custom sampler required
• Supports:
  • Int ranges
  • Float ranges
  • Prompt batches
  • LoRA batches
• Clean visualization
• Safe passthrough when disabled

Designed to be simple, flexible, and non-invasive.

Installation

You can install this extension in two ways:

1. Through ComfyUI Manager (recommended)

Open ComfyUI Manager → Install,
then simply search for AK XZ in the search bar.
Select the extension and click Install.

2. Manual installation

cd ComfyUI/custom_nodes
git clone https://github.com/akawana/ComfyUI-AK-XZ-Axis.git
