+#### Response Compression
+
+API responses (JSON, HTML, JS, CSS, SVG) are gzipped before being sent. Already-compressed responses — PNG, WebP, JPEG, MP4 — are passed through untouched, since compressing them costs CPU and returns a body no smaller than the original.
+
+Compression runs on the server's event loop, which means it blocks *everything else* for its duration: no other request is served and no progress event is delivered while it runs. The `gzip_compresslevel` setting controls that trade-off:
+
+```yaml
+gzip_compresslevel: 9 # default value
+```
+
+| Value  | Behavior                                                                                       |
+| ------ | ---------------------------------------------------------------------------------------------- |
+| `0`    | No compression. Responses are sent as-is and the compression middleware is not installed.       |
+| `1`    | Fastest compression, slightly larger output.                                                    |
+| `2`–`8` | Progressively slower, marginally smaller.                                                      |
+| `9`    | Smallest output, by far the slowest. This is the default.                                       |
+
+If the UI feels sluggish while a large library is being browsed, lowering this is one of the cheapest wins available. Measured on the image-name list of a 200,000-image library (8.48 MB of JSON):
+
+| Level | Time    | Output    |
+| ----- | ------: | --------: |
+| `1`   | 16.4 ms | 6.1% of input |
+| `6`   | 36.1 ms | 5.9% of input |
+| `9`   | 90.2 ms | 5.7% of input |
+
+Level 9 spends 5.5× the event-loop time to save 0.4 percentage points of bandwidth. On a locally-served install the bandwidth is free and the stall is not, so `gzip_compresslevel: 1` is usually the better setting there — the default stays at `9` only so that upgrading does not silently change how anyone's install behaves.
+
+:::tip[Behind a reverse proxy]
+If you serve InvokeAI through nginx, Caddy, or similar, set `gzip_compresslevel: 0` and let the proxy compress instead. The proxy does that work in its own process rather than on InvokeAI's event loop, and it avoids compressing the same bytes twice.

+title: Blocking Work in API Routes
+---
+
+Almost every service in the backend is synchronous — the database layer, the model
+manager, the file stores. The API layer in front of them is asynchronous. Getting the
+boundary between the two wrong does not produce a slow endpoint; it produces a server
+that stops answering entirely.
+
+## The rule
+
+**A route handler that only calls synchronous services must be declared `def`, not
+`async def`.**
+
+```python
+# Correct — Starlette runs this in a worker thread.
+@gallery_router.get("/items/names")
+def get_gallery_item_names(current_user: CurrentUserOrDefault) -> GalleryItemNamesResult:
+    return ApiDependencies.invoker.services.gallery.list_item_names(...)
+```
+
+```python
+# Wrong — the database query runs on the event loop.
+@gallery_router.get("/items/names")
+async def get_gallery_item_names(current_user: CurrentUserOrDefault) -> GalleryItemNamesResult:
+    return ApiDependencies.invoker.services.gallery.list_item_names(...)
+```
+
+The same rule applies to **dependencies**, not just handlers. A dependency declared
+`async def` that performs a synchronous database lookup blocks the loop on every request
+that uses it.
+
+## Why it matters
+
+The server runs as a single process with a single event loop. Anything executed directly
+on that loop has the whole process to itself until it returns. Blocking work on the loop
+therefore does not just delay its own response — for its entire duration the process
+serves **no** other HTTP request and delivers **no** socket.io event. Users do not
+experience this as one slow endpoint; they experience it as the application freezing,
+typically mid-generation, because progress events stop arriving too.
+
+The cost scales with the user's library, not with the developer's. A gallery query that
+returns in milliseconds against a test database can take minutes against a multi-gigabyte
+one — for example a metadata search, which has to read every row's metadata blob.
+
+Declaring the handler `def` makes FastAPI dispatch it to a worker thread instead, leaving
+the loop free to serve everything else.
+
+## When `async def` is right
+
+Use `async def` when the body actually awaits something — streaming a response, awaiting
+another async API, or coordinating tasks. If such a handler *also* performs blocking work,
+that work must be wrapped explicitly:
+
+```python
+from starlette.concurrency import run_in_threadpool
+
+user = await run_in_threadpool(ApiDependencies.invoker.services.users.get, user_id)
+```
+
+`async def` with no `await` in the body is always a mistake: it gains nothing and costs
+the loop.
+
+## What this does not fix
+
+Moving work to the threadpool does not make it faster, and it does not make it parallel.
+The SQLite layer uses a single connection behind a process-wide lock, so database work
+remains serialized regardless of which thread requests it. The benefit is confined to —
+and this is the point — keeping everything *else* responsive while it runs.
+
+## Testing it
+
+Two tests cover this, and they do different jobs.
+
+`tests/app/routers/test_no_blocking_async_routes.py` **enforces the rule**: it parses every
+router module and fails if any route handler is `async def` without awaiting anything. This
+is the one that catches a new route — a per-route test cannot, because the route does not
+exist when the test is written.
+
+`tests/app/routers/test_event_loop_blocking.py` **proves the effect** for a few
+representative routes. It stubs a service method to block synchronously, issues a request
+against the route under test, and asserts that an unrelated trivial route still answers
+while that request is in flight.
+
+Note what the second one measures: not the slow request's own duration, which the fix does
+not change, but the latency of other requests during it. A benchmark of the slow endpoint
+alone will show no improvement and is the wrong instrument here.
+
+If you call a route handler directly from a test, call it like the plain function it now is
+— no `await`, no `asyncio.run`.

Useful for development.\n    dev_reload: Automatically reload when Python sources are changed. Does not reload node definitions.\n    profile_graphs: Enable graph profiling using `cProfile`.\n    profile_prefix: An optional prefix for profile output files.\n    profiles_dir: Path to profiles output directory.\n    max_cache_ram_gb: The maximum amount of CPU RAM to use for model caching in GB. If unset, the limit will be configured based on the available RAM. In most cases, it is recommended to leave this unset.\n    max_cache_vram_gb: The amount of VRAM to use for model caching in GB. If unset, the limit will be configured based on the available VRAM and the device_working_mem_gb. In most cases, it is recommended to leave this unset.\n    log_memory_usage: If True, a memory snapshot will be captured before and after every model cache operation, and the result will be logged (at debug level). There is a time cost to capturing the memory snapshots, so it is recommended to only enable this feature if you are actively inspecting the model cache's behaviour.\n    model_cache_keep_alive_min: How long to keep models in cache after last use, in minutes. A value of 0 (the default) means models are kept in cache indefinitely. If no model generations occur within the timeout period, the model cache is cleared using the same logic as the 'Clear Model Cache' button.\n    device_working_mem_gb: The amount of working memory to keep available on the compute device (in GB). Has no effect if running on CPU. If you are experiencing OOM errors, try increasing this value.\n    enable_partial_loading: Enable partial loading of models. This enables models to run with reduced VRAM requirements (at the cost of slower speed) by streaming the model from RAM to VRAM as its used. In some edge cases, partial loading can cause models to run more slowly if they were previously being fully loaded into VRAM.\n    keep_ram_copy_of_weights: Whether to keep a full RAM copy of a model's weights when the model is loaded in VRAM. Keeping a RAM copy increases average RAM usage, but speeds up model switching and LoRA patching (assuming there is sufficient RAM). Set this to False if RAM pressure is consistently high.\n    ram: DEPRECATED: This setting is no longer used.

This config setting will be removed once the new model cache behavior is stable.\n    pytorch_cuda_alloc_conf: Configure the Torch CUDA memory allocator. This will impact peak reserved VRAM usage and performance. Setting to \"backend:cudaMallocAsync\" works well on many systems. The optimal configuration is highly dependent on the system configuration (device type, VRAM, CUDA driver version, etc.), so must be tuned experimentally.\n    device: Preferred execution device. `auto` will choose the device depending on the hardware platform and the installed torch capabilities.<br>Valid values: `auto`, `cpu`, `cuda`, `mps`, `cuda:N` (where N is a device number)\n    precision: Floating point precision. `float16` will consume half the memory of `float32` but produce slightly lower-quality images.

All settings are lossless. 0 = no compression, 1 = fastest with slightly larger filesize, 9 = slowest with smallest filesize. 1 is typically the best setting.\n    max_queue_size: Maximum number of items in the session queue.\n    session_queue_mode: Session queue mode. Use 'FIFO' for traditional first-in-first-out, or 'round_robin' to serve each user's jobs in turn. In single-user mode, FIFO is always used regardless of this setting.<br>Valid values: `FIFO`, `round_robin`\n    clear_queue_on_startup: Empties session queue on startup.

Omit to deny none.\n    node_cache_size: How many cached nodes to keep in memory.\n    hashing_algorithm: Model hashing algorthim for model installs. 'blake3_multi' is best for SSDs. 'blake3_single' is best for spinning disk HDDs. 'random' disables hashing, instead assigning a UUID to models. Useful when using a memory db to reduce model installation time, or if you don't care about storing stable hashes for models. Alternatively, any other hashlib algorithm is accepted, though these are not nearly as performant as blake3.<br>Valid values: `blake3_multi`, `blake3_single`, `random`, `md5`, `sha1`, `sha224`, `sha256`, `sha384`, `sha512`, `blake2b`, `blake2s`, `sha3_224`, `sha3_256`, `sha3_384`, `sha3_512`, `shake_128`, `shake_256`\n    remote_api_tokens: List of regular expression and token pairs used when downloading models from URLs. The download URL is tested against the regex, and if it matches, the token is provided in as a Bearer token.\n    scan_models_on_startup: Scan the models directory on startup, registering orphaned models. This is typically only used in conjunction with `use_memory_db` for testing purposes.\n    unsafe_disable_picklescan: UNSAFE. Disable the picklescan security check during model installation. Recommended only for development and testing purposes. This will allow arbitrary code execution during model installation, so should never be used in production.\n    allow_unknown_models: Allow installation of models that we are unable to identify. If enabled, models will be marked as `unknown` in the database, and will not have any metadata associated with them. If disabled, unknown models will be rejected during installation.\n    multiuser: Enable multiuser support. When disabled, the application runs in single-user mode using a default system account with administrator privileges. When enabled, requires user authentication and authorization.\n    strict_password_checking: Enforce strict password requirements. When True, passwords must contain uppercase, lowercase, and numbers. When False (default), any password is accepted but its strength (weak/moderate/strong) is reported to the user.\n    external_alibabacloud_api_key: API key for Alibaba Cloud DashScope image generation.\n    external_alibabacloud_base_url: Base URL override for Alibaba Cloud DashScope image generation.\n    external_gemini_api_key: API key for Gemini image generation.\n    external_openai_api_key: API key for OpenAI image generation.\n    external_gemini_base_url: Base URL override for Gemini image generation.\n    external_openai_base_url: Base URL override for OpenAI image generation.\n    external_seedream_api_key: API key for Seedream image generation.\n    external_seedream_base_url: Base URL override for Seedream image generation.\n    base_url: Public base path when running behind a reverse proxy under a sub-path, e.g. `/invoke`. Set only when the proxy PRESERVES the sub-path (the backend receives `/invoke/api/...`). Leave unset when the proxy strips the sub-path or when serving at the domain root.\n    forwarded_allow_ips: Comma-separated list of IPs (or `*`) allowed to set X-Forwarded-* headers.

Useful when using a memory db to reduce model installation time, or if you don't care about storing stable hashes for models. Alternatively, any other hashlib algorithm is accepted, though these are not nearly as performant as blake3.<br>Valid values: `blake3_multi`, `blake3_single`, `random`, `md5`, `sha1`, `sha224`, `sha256`, `sha384`, `sha512`, `blake2b`, `blake2s`, `sha3_224`, `sha3_256`, `sha3_384`, `sha3_512`, `shake_128`, `shake_256`\n    remote_api_tokens: List of regular expression and token pairs used when downloading models from URLs. The download URL is tested against the regex, and if it matches, the token is provided in as a Bearer token.\n    scan_models_on_startup: Scan the models directory on startup, registering orphaned models. This is typically only used in conjunction with `use_memory_db` for testing purposes.\n    unsafe_disable_picklescan: UNSAFE. Disable the picklescan security check during model installation. Recommended only for development and testing purposes. This will allow arbitrary code execution during model installation, so should never be used in production.\n    allow_unknown_models: Allow installation of models that we are unable to identify. If enabled, models will be marked as `unknown` in the database, and will not have any metadata associated with them. If disabled, unknown models will be rejected during installation.\n    multiuser: Enable multiuser support. When disabled, the application runs in single-user mode using a default system account with administrator privileges. When enabled, requires user authentication and authorization.\n    strict_password_checking: Enforce strict password requirements. When True, passwords must contain uppercase, lowercase, and numbers. When False (default), any password is accepted but its strength (weak/moderate/strong) is reported to the user.\n    external_alibabacloud_api_key: API key for Alibaba Cloud DashScope image generation.\n    external_alibabacloud_base_url: Base URL override for Alibaba Cloud DashScope image generation.\n    external_gemini_api_key: API key for Gemini image generation.\n    external_openai_api_key: API key for OpenAI image generation.\n    external_gemini_base_url: Base URL override for Gemini image generation.\n    external_openai_base_url: Base URL override for OpenAI image generation.\n    external_seedream_api_key: API key for Seedream image generation.\n    external_seedream_base_url: Base URL override for Seedream image generation.\n    base_url: Public base path when running behind a reverse proxy under a sub-path, e.g. `/invoke`. Set only when the proxy PRESERVES the sub-path (the backend receives `/invoke/api/...`). Leave unset when the proxy strips the sub-path or when serving at the domain root.\n    forwarded_allow_ips: Comma-separated list of IPs (or `*`) allowed to set X-Forwarded-* headers. Set to the reverse proxy's IP. Only used when `base_url` is set.\n    gzip_compresslevel: GZip compression level for API responses. 0 disables response compression entirely, 1 is fastest, 9 (the default) is smallest. Compression runs on the event loop and blocks the whole server while it works, and level 9 costs about 5.5x the time of level 1 for 0.4 percentage points of extra compression, so lowering this makes the app noticeably more responsive on large libraries. Set to 0 when a reverse proxy already compresses responses."

+Declaring these routes `def` hands them to Starlette's threadpool instead, leaving the

+"""Router-level tests for GET /api/v1/gallery/item_names.
+
+This endpoint replaces two deprecated ones — `/gallery/items/names` and
+`/virtual_boards/by_date/{date}/item_names` — with a flat name list. The deprecated shape
+wrapped every name in an object carrying a `kind` discriminator, which cost one model per row
+(~800ms on a 200k-item library) for a value callers derive from the file extension.
+
+What matters here is that the replacement is faithful: same order, same filtering, same
+per-user isolation, and videos still present. Where possible that is asserted *against* the
+deprecated endpoint rather than against hardcoded expectations, so the two cannot drift while
+both are still served.
