Command-Line Interface |
The InvokeAI command line interface (CLI) provides scriptable access to InvokeAI's features.Some advanced features are only available through the CLI, though they eventually find their way into the WebUI.
The CLI is accessible from the invoke.sh/invoke.bat launcher by
selecting option (1). Alternatively, it can be launched directly from
the command line by activating the InvokeAI environment and giving the
command:
invokeaiAfter some startup messages, you will be presented with the invoke>
prompt. Here you can type prompts to generate images and issue other
commands to load and manipulate generative models. The CLI has a large
number of command-line options that control its behavior. To get a
concise summary of the options, call invokeai with the --help argument:
invokeai --helpThe script uses the readline library to allow for in-line editing, command history (++up++ and ++down++), autocompletion, and more. To help keep track of which prompts generated which images, the script writes a log file of image names and prompts to the selected output directory.
Here is a typical session

The script recognizes a series of command-line switches that will change important global defaults, such as the directory for image outputs and the location of the model weight files.
These command-line arguments can be passed to invoke.py when you first run it
from the Windows, Mac or Linux command line. Some set defaults that can be
overridden on a per-prompt basis (see

</div>
!!! tip
On Windows systems, you may run into
problems when passing the invoke script standard backslashed path
names because the Python interpreter treats "\" as an escape.
You can either double your slashes (ick): `C:\\path\\to\\my\\file`, or
use Linux/Mac style forward slashes (better): `C:/path/to/my/file`.
To start up invoke.py with your preferred settings, place your desired
startup options in a file in your home directory named .invokeai The
file should contain the startup options as you would type them on the
command line (--steps=10 --grid), one argument per line, or a
mixture of both using any of the accepted command switch formats:
!!! example "my unmodified initialization file"
```bash title="~/.invokeai" linenums="1"
# InvokeAI initialization file
# This is the InvokeAI initialization file, which contains command-line default values.
# Feel free to edit. If anything goes wrong, you can re-initialize this file by deleting
# or renaming it and then running invokeai-configure again.
# The --root option below points to the folder in which InvokeAI stores its models, configs and outputs.
--root="/Users/mauwii/invokeai"
# the --outdir option controls the default location of image files.
--outdir="/Users/mauwii/invokeai/outputs"
# You may place other frequently-used startup commands here, one or more per line.
# Examples:
# --web --host=0.0.0.0
# --steps=20
# -Ak_euler_a -C10.0
```
!!! note
The initialization file only accepts the command line arguments.
There are additional arguments that you can provide on the `invoke>` command
line (such as `-n` or `--iterations`) that cannot be entered into this file.
Also be alert for empty blank lines at the end of the file, which will cause
an arguments error at startup time.
After the invoke.py script initializes, it will present you with a invoke>
prompt. Here you can enter information to generate images from text
(txt2img), to embellish an existing image or sketch
(img2img), or to selectively alter chosen regions of the image
(inpainting).
!!! example ""
```bash
invoke> waterfall and rainbow -W640 -H480
```
This will create the requested image with the dimensions 640 (width)
and 480 (height).
Here are the invoke> command that apply to txt2img:
| Argument |

6 |
Select level of compression for output files, from 0 (no compression) to 9 (max compression) |
--grid |

Select face restoration algorithm to use: gfpgan, codeformer |
--codeformer_fidelity |
-cf <float> |
0.75 |
Used along with CodeFormer. Takes values between 0 and 1. 0 produces high quality but low accuracy. 1 produces high accuracy but low quality |
--save_original |
-save_orig |
False |
When upscaling or fixing faces, this will cause the original image to be saved rather than replaced. |
--variation <float> |
-v<float> |
0.0 |
Add a bit of noise (0.0=none, 1.0=high) to the image in order to generate a series of variations. Usually used in combination with -S<seed> and -n<int> to generate a series a riffs on a starting image. See Variations. |

--v_symmetry_time_pct <float> |
None |
Create symmetry along the Y axis at the desired percent complete of the generation process. (Must be between 0.0 and 1.0; set to a very small number like 0.0001 for just after the first step of generation.) |
!!! note
the width and height of the image must be multiples of 64. You can
provide different values, but they will be rounded down to the nearest multiple
of 64.
!!! example "This is a example of img2img"
```bash
invoke> waterfall and rainbow -I./vacation-photo.png -W640 -H480 --fit
```
This will modify the indicated vacation photograph by making it more like the prompt. Results will vary greatly depending on what is in the image. We also ask to --fit the image into a box no bigger than 640x480. Otherwise the image size will be identical to the provided photo and you may run out of memory if it is large.
In addition to the command-line options recognized by txt2img, img2img accepts additional options:
| Argument |
Shortcut | Default | Description |
|---|---|---|---|
--init_img <path> |
-I<path> |
None |
Path to the initialization image |
--fit |
-F |
False |
Scale the image to fit into the specified -H and -W dimensions |
--strength <float> |
-s<float> |
0.75 |
How hard to try to match the prompt to the initial image. Ranges from 0.0-0.99, with higher values replacing the initial image completely. |
!!! example ""
```bash
invoke> waterfall and rainbow -I./vacation-photo.png -M./vacation-mask.png -W640 -H480 --fit
```
This will do the same thing as img2img, but image alterations will
only occur within transparent areas defined by the mask file specified
by `-M`. You may also supply just a single initial image with the areas
to overpaint made transparent, but you must be careful not to destroy
the pixels underneath when you create the transparent areas. See
[Inpainting](INPAINTING.md) for details.
inpainting accepts all the arguments used for txt2img and img2img, as well as the --mask (-M) and --text_mask (-tm) arguments:
| Argument |
Shortcut | Default | Description |
|---|---|---|---|
--init_mask <path> |
-M<path> |
None |
Path to an image the same size as the initial_image, with areas for inpainting made transparent. |
--invert_mask |
False | If true, invert the mask so that transparent areas are opaque and vice versa. | |
--text_mask <prompt> [<float>] |
-tm <prompt> [<float>] |
Create a mask from a text prompt describing part of the image |
The mask may either be an image with transparent areas, in which case the inpainting will occur in the transparent areas only, or a black and white image, in which case all black areas will be painted into.
--text_mask (short form -tm) is a way to generate a mask using a text
description of the part of the image to replace. For example, if you have an
image of a breakfast plate with a bagel, toast and scrambled eggs, you can
selectively mask the bagel and replace it with a piece of cake this way:
invoke> a piece of cake -I /path/to/breakfast.png -tm bagelThe algorithm uses clipseg to classify different
regions of the image. The classifier puts out a confidence score for each region
it identifies. Generally regions that score above 0.5 are reliable, but if you
are getting too much or too little masking you can adjust the threshold down (to
get more mask), or up (to get less). In this example, by passing -tm a higher
value, we are insisting on a more stringent classification.
invoke> a piece of cake -I /path/to/breakfast.png -tm bagel 0.6You can load and use hundreds of community-contributed Textual Inversion models just by typing the appropriate trigger phrase. Please see Concepts Library for more details.
The CLI offers a number of commands that begin with "!".
To postprocess a file using face restoration or upscaling, use the !fix
command.
This command runs a post-processor on a previously-generated image. It takes a
PNG filename or path and applies your choice of the -U, -G, or --embiggen
switches in order to fix faces or upscale. If you provide a filename, the script
will look for it in the current output directory. Otherwise you can provide a
full or partial path to the desired file.
Some examples:
!!! example "Upscale to 4X its original size and fix faces using codeformer"
```bash
invoke> !fix 0000045.4829112.png -G1 -U4 -ft codeformer
```
!!! example "Use the GFPGAN algorithm to fix faces, then upscale to 3X using --embiggen"
```bash
invoke> !fix 0000045.4829112.png -G0.8 -ft gfpgan
>> fixing outputs/img-samples/0000045.4829112.png
>> retrieved seed 4829112 and prompt "boy enjoying a banana split"
>> GFPGAN - Restoring Faces for image seed:4829112
Outputs:
[1] outputs/img-samples/000017.4829112.gfpgan-00.png: !fix "outputs/img-samples/0000045.4829112.png" -s 50 -S -W 512 -H 512 -C 7.5 -A k_lms -G 0.8
```
This command takes an image, a text prompt, and uses the clipseg algorithm to
automatically generate a mask of the area that matches the text prompt. It is
useful for debugging the text masking process prior to inpainting with the
--text_mask argument. See [INPAINTING.md] for details.
The CLI allows you to add new models on the fly, as well as to switch among them rapidly without leaving the script. There are several different model formats, each described in the Model Installation Guide.
This prints out a list of the models defined in `config/models.yaml'. The active model is bold-faced
Example:
inpainting-1.5 not loaded Stable Diffusion inpainting model stable-diffusion-1.5 active Stable Diffusion v1.5 waifu-diffusion not loaded Waifu Diffusion v1.4
This quickly switches from one model to another without leaving the CLI script.
invoke.py uses a memory caching system; once a model has been loaded,
switching back and forth is quick. The following example shows this in action.
Note how the second column of the !models table changes to cached after a
model is first loaded, and that the long initialization step is not needed when
loading a cached model.
This imports and installs a diffusers-style model that is stored on
the HuggingFace Web Site. You can look up
any Stable Diffusion diffusers
model and install it
with a command like the following:
!import_model prompthero/openjourneyIf you have a copy of a diffusers-style model saved to disk, you can
import it by passing the path to model's top-level directory.
For a .ckpt or .safetensors file, if you have a direct download
URL for the file, you can provide it to !import_model and the file
will be downloaded and installed for you.
This command imports a new model weights file into InvokeAI, makes it available
for image generation within the script, and writes out the configuration for the
model into config/models.yaml for use in subsequent sessions.
Provide !import_model with the path to a weights file ending in .ckpt. If
you type a partial path and press tab, the CLI will autocomplete. Although it
will also autocomplete to .vae files, these are not currenty supported (but
will be soon).
When you hit return, the CLI will prompt you to fill in additional information
about the model, including the short name you wish to use for it with the
!switch command, a brief description of the model, the default image width and
height to use with this model, and the model's configuration file. The latter
three fields are automatically filled with reasonable defaults. In the example
below, the bold-faced text shows what the user typed in with the exception of
the width, height and configuration file paths, which were filled in
automatically.
If you provide the path of a directory that contains one or more
.ckpt or .safetensors files, the CLI will scan the directory and
interactively offer to import the models it finds there. Also see the
--autoconvert command-line option.
The !edit_model command can be used to modify a model that is already defined
in config/models.yaml. Call it with the short name of the model you wish to
modify, and it will allow you to modify the model's description, weights and
other fields.
Example:
invoke> !edit_model waifu-diffusion >> Editing model waifu-diffusion from configuration file ./configs/models.yaml description: Waifu diffusion v1.4beta weights: models/ldm/stable-diffusion-v1/model-epoch10-float16.ckpt config: configs/stable-diffusion/v1-inference.yaml width: 512 height: 512 >> New configuration: waifu-diffusion: config: configs/stable-diffusion/v1-inference.yaml description: Waifu diffusion v1.4beta weights: models/ldm/stable-diffusion-v1/model-epoch10-float16.ckpt height: 512 width: 512 OK to import [n]? y >> Caching model stable-diffusion-1.4 in system RAM >> Loading waifu-diffusion from models/ldm/stable-diffusion-v1/model-epoch10-float16.ckpt ...
The CLI provides a series of convenient commands for reviewing previous actions, retrieving them, modifying them, and re-running them.
The invoke script keeps track of all the commands you issue during a session, allowing you to re-run them. On Mac and Linux systems, it also writes the command-line history out to disk, giving you access to the most recent 1000 commands issued.
The !history command will return a numbered list of all the commands issued
during the session (Windows), or the most recent 1000 commands (Mac|Linux). You
can then repeat a command by using the command !NNN, where "NNN" is the
history line number. For example:
!!! example ""
```bash
invoke> !history
...
[14] happy woman sitting under tree wearing broad hat and flowing garment
[15] beautiful woman sitting under tree wearing broad hat and flowing garment
[18] beautiful woman sitting under tree wearing broad hat and flowing garment -v0.2 -n6
[20] watercolor of beautiful woman sitting under tree wearing broad hat and flowing garment -v0.2 -n6 -S2878767194
[21] surrealist painting of beautiful woman sitting under tree wearing broad hat and flowing garment -v0.2 -n6 -S2878767194
...
invoke> !20
invoke> watercolor of beautiful woman sitting under tree wearing broad hat and flowing garment -v0.2 -n6 -S2878767194
```
####!fetch
This command retrieves the generation parameters from a previously generated image and either loads them into the command line (Linux|Mac), or prints them out in a comment for copy-and-paste (Windows). You may provide either the name of a file in the current output directory, or a full file path. Specify path to a folder with image png files, and wildcard *.png to retrieve the dream command used to generate the images, and save them to a file commands.txt for further processing.
!!! example "load the generation command for a single png file"
```bash
invoke> !fetch 0000015.8929913.png
# the script returns the next line, ready for editing and running:
invoke> a fantastic alien landscape -W 576 -H 512 -s 60 -A plms -C 7.5
```
!!! example "fetch the generation commands from a batch of files and store them into selected.txt"
```bash
invoke> !fetch outputs\selected-imgs\*.png selected.txt
```
This command replays a text file generated by !fetch or created manually
!!! example
```bash
invoke> !replay outputs\selected-imgs\selected.txt
```
!!! note
These commands may behave unexpectedly if given a PNG file that was
not generated by InvokeAI.
This is similar to !history but it only returns lines that contain
search string. For example:
invoke> !search surreal
[21] surrealist painting of beautiful woman sitting under tree wearing broad hat and flowing garment -v0.2 -n6 -S2878767194This clears the search history from memory and disk. Be advised that this operation is irreversible and does not issue any warnings!
The command-line offers convenient history tracking, editing, and command completion.
- To scroll through previous commands and potentially edit/reuse them, use the ++up++ and ++down++ keys.
- To edit the current command, use the ++left++ and ++right++ keys to position the cursor, and then ++backspace++, ++delete++ or insert characters.
- To move to the very beginning of the command, type ++ctrl+a++ (or ++command+a++ on the Mac)
- To move to the end of the command, type ++ctrl+e++.
- To cut a section of the command, position the cursor where you want to start cutting and type ++ctrl+k++
- To paste a cut section back in, position the cursor where you want to paste, and type ++ctrl+y++
Windows users can get similar, but more limited, functionality if they launch
invoke.py with the winpty program and have the pyreadline3 library
installed:
> winpty python scripts\invoke.pyOn the Mac and Linux platforms, when you exit invoke.py, the last 1000 lines of
your command-line history will be saved. When you restart invoke.py, you can
access the saved history using the ++up++ key.
In addition, limited command-line completion is installed. In various contexts, you can start typing your command and press ++tab++. A list of potential completions will be presented to you. You can then type a little more, hit ++tab++ again, and eventually autocomplete what you want.
When specifying file paths using the one-letter shortcuts, the CLI will attempt
to complete pathnames for you. This is most handy for the -I (init image) and
-M (init mask) paths. To initiate completion, start the path with a slash
(/) or ./. For example:
invoke> zebra with a mustache -I./test-pictures<TAB>
-I./test-pictures/Lincoln-and-Parrot.png -I./test-pictures/zebra.jpg -I./test-pictures/madonna.png
-I./test-pictures/bad-sketch.png -I./test-pictures/man_with_eagle/You can then type ++z++, hit ++tab++ again, and it will autofill to zebra.jpg.
More text completion features (such as autocompleting seeds) are on their way.
