--- title: Configuration --- # :material-tune-variant: InvokeAI Configuration ## Intro InvokeAI has numerous runtime settings which can be used to adjust many aspects of its operations, including the location of files and directories, memory usage, and performance. These settings can be viewed and customized in several ways: 1. By editing settings in the `invokeai.yaml` file. 2. By setting environment variables. 3. On the command-line, when InvokeAI is launched. In addition, the most commonly changed settings are accessible graphically via the `invokeai-configure` script. ### How the Configuration System Works When InvokeAI is launched, the very first thing it needs to do is to find its "root" directory, which contains its configuration files, installed models, its database of images, and the folder(s) of generated images themselves. In this document, the root directory will be referred to as ROOT. #### Finding the Root Directory To find its root directory, InvokeAI uses the following recipe: 1. It first looks for the argument `--root ` on the command line it was launched from, and uses the indicated path if present. 2. Next it looks for the environment variable INVOKEAI_ROOT, and uses the directory path found there if present. 3. If neither of these are present, then InvokeAI looks for the folder containing the `.venv` Python virtual environment directory for the currently active environment. This directory is checked for files expected inside the InvokeAI root before it is used. 4. Finally, InvokeAI looks for a directory in the current user's home directory named `invokeai`. #### Reading the InvokeAI Configuration File Once the root directory has been located, InvokeAI looks for a file named `ROOT/invokeai.yaml`, and if present reads configuration values from it. The top of this file looks like this: ``` InvokeAI: Web Server: host: localhost port: 9090 allow_origins: [] allow_credentials: true allow_methods: - '*' allow_headers: - '*' Features: esrgan: true internet_available: true log_tokenization: false patchmatch: true restore: true ... ``` This lines in this file are used to establish default values for Invoke's settings. In the above fragment, the Web Server's listening port is set to 9090 by the `port` setting. You can edit this file with a text editor such as "Notepad" (do not use Word or any other word processor). When editing, be careful to maintain the indentation, and do not add extraneous text, as syntax errors will prevent InvokeAI from launching. A basic guide to the format of YAML files can be found [here](https://circleci.com/blog/what-is-yaml-a-beginner-s-guide/). You can fix a broken `invokeai.yaml` by deleting it and running the configuration script again -- option [7] in the launcher, "Re-run the configure script". #### Reading Environment Variables Next InvokeAI looks for defined environment variables in the format `INVOKEAI_`, for example `INVOKEAI_port`. Environment variable values take precedence over configuration file variables. On a Macintosh system, for example, you could change the port that the web server listens on by setting the environment variable this way: ``` export INVOKEAI_port=8000 invokeai-web ``` Please check out these [Macintosh](https://phoenixnap.com/kb/set-environment-variable-mac) and [Windows](https://phoenixnap.com/kb/windows-set-environment-variable) guides for setting temporary and permanent environment variables. #### Reading the Command Line Lastly, InvokeAI takes settings from the command line, which override everything else. The command-line settings have the same name as the corresponding configuration file settings, preceded by a `--`, for example `--port 8000`. If you are using the launcher (`invoke.sh` or `invoke.bat`) to launch InvokeAI, then just pass the command-line arguments to the launcher: ``` invoke.bat --port 8000 --host 0.0.0.0 ``` The arguments will be applied when you select the web server option (and the other options as well). If, on the other hand, you prefer to launch InvokeAI directly from the command line, you would first activate the virtual environment (known as the "developer's console" in the launcher), and run `invokeai-web`: ``` > C:\Users\Fred\invokeai\.venv\scripts\activate (.venv) > invokeai-web --port 8000 --host 0.0.0.0 ``` You can get a listing and brief instructions for each of the command-line options by giving the `--help` argument: ``` (.venv) > invokeai-web --help usage: InvokeAI [-h] [--host HOST] [--port PORT] [--allow_origins [ALLOW_ORIGINS ...]] [--allow_credentials | --no-allow_credentials] [--allow_methods [ALLOW_METHODS ...]] [--allow_headers [ALLOW_HEADERS ...]] [--esrgan | --no-esrgan] [--internet_available | --no-internet_available] [--log_tokenization | --no-log_tokenization] [--patchmatch | --no-patchmatch] [--restore | --no-restore] [--always_use_cpu | --no-always_use_cpu] [--free_gpu_mem | --no-free_gpu_mem] [--max_loaded_models MAX_LOADED_MODELS] [--max_cache_size MAX_CACHE_SIZE] [--max_vram_cache_size MAX_VRAM_CACHE_SIZE] [--gpu_mem_reserved GPU_MEM_RESERVED] [--precision {auto,float16,float32,autocast}] [--sequential_guidance | --no-sequential_guidance] [--xformers_enabled | --no-xformers_enabled] [--tiled_decode | --no-tiled_decode] [--root ROOT] [--autoimport_dir AUTOIMPORT_DIR] [--lora_dir LORA_DIR] [--embedding_dir EMBEDDING_DIR] [--controlnet_dir CONTROLNET_DIR] [--conf_path CONF_PATH] [--models_dir MODELS_DIR] [--legacy_conf_dir LEGACY_CONF_DIR] [--db_dir DB_DIR] [--outdir OUTDIR] [--from_file FROM_FILE] [--use_memory_db | --no-use_memory_db] [--model MODEL] [--log_handlers [LOG_HANDLERS ...]] [--log_format {plain,color,syslog,legacy}] [--log_level {debug,info,warning,error,critical}] [--version | --no-version] ``` ## The Configuration Settings The configuration settings are divided into several distinct groups in `invokeia.yaml`: ### Web Server | Setting | Default Value | Description | |----------|----------------|--------------| | `host` | `localhost` | Name or IP address of the network interface that the web server will listen on | | `port` | `9090` | Network port number that the web server will listen on | | `allow_origins` | `[]` | A list of host names or IP addresses that are allowed to connect to the InvokeAI API in the format `['host1','host2',...]` | | `allow_credentials | `true` | Require credentials for a foreign host to access the InvokeAI API (don't change this) | | `allow_methods` | `*` | List of HTTP methods ("GET", "POST") that the web server is allowed to use when accessing the API | | `allow_headers` | `*` | List of HTTP headers that the web server will accept when accessing the API | The documentation for InvokeAI's API can be accessed by browsing to the following URL: [http://localhost:9090/docs]. ### Features These configuration settings allow you to enable and disable various InvokeAI features: | Setting | Default Value | Description | |----------|----------------|--------------| | `esrgan` | `true` | Activate the ESRGAN upscaling options| | `internet_available` | `true` | When a resource is not available locally, try to fetch it via the internet | | `log_tokenization` | `false` | Before each text2image generation, print a color-coded representation of the prompt to the console; this can help understand why a prompt is not working as expected | | `patchmatch` | `true` | Activate the "patchmatch" algorithm for improved inpainting | ### Generation These options tune InvokeAI's memory and performance characteristics. | Setting | Default Value | Description | |-----------------------|---------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `sequential_guidance` | `false` | Calculate guidance in serial rather than in parallel, lowering memory requirements at the cost of some performance loss | | `attention_type` | `auto` | Select the type of attention to use. One of `auto`,`normal`,`xformers`,`sliced`, or `torch-sdp` | | `attention_slice_size` | `auto` | When "sliced" attention is selected, set the slice size. One of `auto`, `balanced`, `max` or the integers 1-8| | `force_tiled_decode` | `false` | Force the VAE step to decode in tiles, reducing memory consumption at the cost of performance | ### Device These options configure the generation execution device. | Setting | Default Value | Description | |-----------------------|---------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `device` | `auto` | Preferred execution device. One of `auto`, `cpu`, `cuda`, `cuda:1`, `mps`. `auto` will choose the device depending on the hardware platform and the installed torch capabilities. | | `precision` | `auto` | Floating point precision. One of `auto`, `float16` or `float32`. `float16` will consume half the memory of `float32` but produce slightly lower-quality images. The `auto` setting will guess the proper precision based on your video card and operating system | ### Paths These options set the paths of various directories and files used by InvokeAI. Relative paths are interpreted relative to INVOKEAI_ROOT, so if INVOKEAI_ROOT is `/home/fred/invokeai` and the path is `autoimport/main`, then the corresponding directory will be located at `/home/fred/invokeai/autoimport/main`. | Setting | Default Value | Description | |----------|----------------|--------------| | `autoimport_dir` | `autoimport/main` | At startup time, read and import any main model files found in this directory | | `lora_dir` | `autoimport/lora` | At startup time, read and import any LoRA/LyCORIS models found in this directory | | `embedding_dir` | `autoimport/embedding` | At startup time, read and import any textual inversion (embedding) models found in this directory | | `controlnet_dir` | `autoimport/controlnet` | At startup time, read and import any ControlNet models found in this directory | | `conf_path` | `configs/models.yaml` | Location of the `models.yaml` model configuration file | | `models_dir` | `models` | Location of the directory containing models installed by InvokeAI's model manager | | `legacy_conf_dir` | `configs/stable-diffusion` | Location of the directory containing the .yaml configuration files for legacy checkpoint models | | `db_dir` | `databases` | Location of the directory containing InvokeAI's image, schema and session database | | `outdir` | `outputs` | Location of the directory in which the gallery of generated and uploaded images will be stored | | `use_memory_db` | `false` | Keep database information in memory rather than on disk; this will not preserve image gallery information across restarts | Note that the autoimport directories will be searched recursively, allowing you to organize the models into folders and subfolders in any way you wish. In addition, while we have split up autoimport directories by the type of model they contain, this isn't necessary. You can combine different model types in the same folder and InvokeAI will figure out what they are. So you can easily use just one autoimport directory by commenting out the unneeded paths: ``` Paths: autoimport_dir: autoimport # lora_dir: null # embedding_dir: null # controlnet_dir: null ``` ### Logging These settings control the information, warning, and debugging messages printed to the console log while InvokeAI is running: | Setting | Default Value | Description | |----------|----------------|--------------| | `log_handlers` | `console` | This controls where log messages are sent, and can be a list of one or more destinations. Values include `console`, `file`, `syslog` and `http`. These are described in more detail below | | `log_format` | `color` | This controls the formatting of the log messages. Values are `plain`, `color`, `legacy` and `syslog` | | `log_level` | `debug` | This filters messages according to the level of severity and can be one of `debug`, `info`, `warning`, `error` and `critical`. For example, setting to `warning` will display all messages at the warning level or higher, but won't display "debug" or "info" messages | Several different log handler destinations are available, and multiple destinations are supported by providing a list: ``` log_handlers: - console - syslog=localhost - file=/var/log/invokeai.log ``` * `console` is the default. It prints log messages to the command-line window from which InvokeAI was launched. * `syslog` is only available on Linux and Macintosh systems. It uses the operating system's "syslog" facility to write log file entries locally or to a remote logging machine. `syslog` offers a variety of configuration options: ``` syslog=/dev/log` - log to the /dev/log device syslog=localhost` - log to the network logger running on the local machine syslog=localhost:512` - same as above, but using a non-standard port syslog=fredserver,facility=LOG_USER,socktype=SOCK_DRAM` - Log to LAN-connected server "fredserver" using the facility LOG_USER and datagram packets. ``` * `http` can be used to log to a remote web server. The server must be properly configured to receive and act on log messages. The option accepts the URL to the web server, and a `method` argument indicating whether the message should be submitted using the GET or POST method. ``` http=http://my.server/path/to/logger,method=POST ``` The `log_format` option provides several alternative formats: * `color` - default format providing time, date and a message, using text colors to distinguish different log severities * `plain` - same as above, but monochrome text only * `syslog` - the log level and error message only, allowing the syslog system to attach the time and date * `legacy` - a format similar to the one used by the legacy 2.3 InvokeAI releases.
