Adds --ocr-engine unlimited, which renders each page with pypdfium2 and parses it with Baidu's Unlimited-OCR model via transformers. Detection tags are stripped and image blocks are cropped into images/ so the existing EPUB step works unchanged. marker remains the default. Measured on an RTX 4060 (8 GB): ~60 s per dense page, peak ~7 GB VRAM, about 4x slower than marker. The advertised speed needs vLLM/SGLang. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Reject empty page selections before writing output.
main.py accepts negative and out-of-range page values. With --ocr-engine unlimited, _page_indices() can return []. convert_pdf() then writes empty Markdown and success metadata without processing a page.
The EPUB stage does not reject the empty file. It adds the file as a chapter, converts its empty content, and writes an EPUB containing no document content.
Reject non-positive max_pages, negative start_page, and any empty computed range.

Bound model coordinates before cropping an image.
_parse_bbox() accepts any increasing coordinates. If the model emits [0,0,999999,999999], the resulting box is far larger than the page, and page_image.crop(box) can allocate excessive memory or fail. Reject coordinates outside the model’s 0–999 range, or clamp the pixel box to the page before cropping. (huggingface.co)

Parse reference-prefixed image blocks before stripping tags.
The model also emits blocks such as <|ref|>image<|/ref|><|det|>[[x1,y1,x2,y2]]<|/det|>. REF_RE.sub() leaves image<|det|>… at the start of that line, so DET_RE.match() fails. The conversion then writes the tag text instead of cropping and linking the image. Parse both supported block forms before removing reference tags. (huggingface.co)

Adds --ocr-engine vllm with --vllm-url and --vllm-workers. Pages are rendered locally and posted to a running vLLM server several at a time so vLLM can batch them; output order, images/ and _metadata.json match the transformers engine, which now shares the rendering and output helpers. If the server is unreachable the error prints the podman command. On an RTX 4060 (8 GB, also driving the desktop) the server only fits with FP8 weights and --skip-mm-profiling. It then reads a 12-page synthetic scan in ~12.5-15 s (~1-1.3 s/page) versus 71 s for marker and 178 s for the transformers engine, with 1-2 misread words in ~2,400. The transformers engine now sets expandable_segments, without which it runs out of memory on Linux, and the README lists torchvision for it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Reject non-positive worker counts during argument parsing.
If the user sets --vllm-workers 0 or a negative value, parsing succeeds but ThreadPoolExecutor rejects the value during conversion. The CLI then fails each queued PDF instead of reporting an invalid option once. Validate that the worker count is positive before processing the queue.

Reject a server that advertises a different model.
If /models lists one unrelated vision model, this fallback selects it and sends Unlimited-OCR prompts to it. The conversion can then write incorrect Markdown as a successful result. Require MODEL_NAME, or accept an explicitly configured model alias rather than any sole model.

vLLM picks the tile grid for Unlimited-OCR from the page's aspect ratio, with up to 32 tiles. On a real scanned book, half of the pages were just wide enough to get a 3x4 grid of upscaled tiles, and encoding them needed 704 MiB at once, which crashed the server on an 8 GB card. Padding each page with white to exactly 2:3 (3:2 for landscape) always gives 6 tiles, like the A4 pages that were benchmarked. 60 pages of that book now run at ~1.5 s per page. Also close the PDF when a request fails, which removes pdfium's "library is destroyed" warning. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
With --ocr-engine vllm, main.py now checks --vllm-url before processing. If nothing answers and the URL is local, it starts the server in a Podman container (pdf2epub-vllm) with the settings that fit an 8 GB card, waits until it serves the model, and stops it again once all PDFs are done, including on errors and Ctrl+C, since it holds most of the GPU memory. --vllm-keep-server leaves it running for the next run. A server that was already running is used and left alone. If the container dies during startup, the error shows its last log lines. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

<title>[Bugfix] Make unspecified --host bind to dual stack</title>
<location>GitHub pull request 22823 in vllm-project/vllm (link omitted to avoid creating a cross-reference)</location>
<excerpt>Passing `--host=""` does not listen on all interfaces, which prevents standard dual-stack and multi-home binding defaulting from working out of the box. It only binds to IPv4 addresses for "" and "0.0.0.0", and only selects ipv4 addresses when `localhost` is provided. ... The convention for binding hosts in Python and in several other language stdlib is that an absent host binds to all addresses for listening. This is the default behavior in uvicorn - resolve the None host via a call to getaddrinfo which returns two addresses for ipv4 and ipv6. ... This PR changes the create_server_socket method to create a list of sockets propagate that to the callers. It is intended to ensure that the same configuration can work in multiple environments regardless of dual-stack, ipv4 only, or ipv6 only enablement. * Make `""` listen on all interfaces. * Make `localhost` listen on all local interfaces ... Tested with the following options to `--host` and expected outcomes: ... ``` --host `@HEAD` this change why None/"" all ipv4 addresses all ipv4 and ipv6 addresses bind to everything by default 0.0.0.0 all ipv4 addresses all ipv4 addresses consistent with how uvicorn behaves :: all ipv4 and ipv6 addresses all ipv4 and ipv6 addresses requires IPv6 to be enabled or fails to listen 127.0.0.1 ipv4 127.0.0.1 ipv4 127.0.0.1 explicit address binding ::1 ipv6 ::1 ipv6 ::1 explicit address binding localhost all local ipv4 addresses all local ipv4 and ipv6 addresses listening on all local devices should be more convenient ``` ... This pull request correctly implements dual-stack binding for the server by creating sockets for all available address families when no host is specified. The changes are propagated correctly through the codebase. However, I&`#39`;ve identified a critical issue that will cause a server crash on startup when no host is specified. Additionally, there are some debug `print` statements that should be replaced with proper logging. ... > Added new test to test_basic that verifies dual binding when ipv4 and ipv6 is available, and when run on a system without either address, that the ipv4 or ipv6 address is not bound ... > `@smarterclayton` I think the tests are failing due to: > ``` > FAILED entrypoints/openai/test_bind.py::test_bind_ipv4_ipv6[default] - requests.exceptions.ConnectionError: HTTPConnectionPool(host=&`#39`;::1&`#39`;, port=34883): Max retries exceeded with url: /health (Caused by NameResolutionError("<urllib3.connection.HTTPConnection object at 0x7fd615d394c0>: Failed to resolve &`#39`;::1&`#39`; ([Errno -9] Address family for hostname not supported)")) > ``` > > and then for some reason that trashes all the subsequent tests ... > > FAILED entrypoints/openai/test_bind.py::test_bind_ipv4_ipv6[default] - requests.exceptions.ConnectionError: HTTPConnectionPool(host=&`#39`;::1&`#39`;, port=34883): Max retries exceeded with url: /health (Caused by NameResolutionError("<urllib3.connection.HTTPConnection object at 0x7fd615d394c0>: Failed to resolve &`#39`;::1&`#39`; ([Errno -9] Address family for hostname not supported)")) > > I think that means we need to filter the test cases to whether the test environment supports IPv6 or IPv4. It probably also means the PR tests won&`#39`;t prevent regressions but someone running locally should catch it.</excerpt>

<title>Server Arguments - vLLM</title>

<excerpt>Server Arguments - vLLM Provide feedback Edit this page # Server Arguments¶ The`vllm serve` command is used to launch the OpenAI-compatible server. ## CLI Arguments¶ The`vllm serve` command is used to launch the OpenAI-compatible server. To see the available options, take a look at the CLI Reference! ## Configuration file¶ You can load CLI arguments via a YAML config file. The argument names must be the long form of those outlined above. For example: ``` # config.yaml model: meta-llama/Llama-3.1-8B-Instruct host: "127.0.0.1" port: 6379 uvicorn-log-level: "info" ``` To use the above config file: ``` vllm serve --config config.yaml ``` ### Generate a configuration from vLLM Recipes¶ vLLM Recipes can be converted into`config.yaml` and`env.sh`. See the Recipes conversion tool README for usage. Source the generated environment before starting vLLM: ``` source env.sh vllm serve --config config.yaml ``` Note In case an argument is supplied simultaneously using command line and the config file, the value from the command line will take precedence. The order of priorities is`command line > config file values > defaults`. e.g.`vllm serve SOME_MODEL --config config.yaml`, SOME_MODEL takes precedence over`model` in config file. --- Addons documentation― Hosted by Read the Docs</excerpt>

Security Misconfiguration
Reachability: External
Exploitability: Moderate
CWE: CWE-1327
Bind the auto-started vLLM server to loopback.
PODMAN_ARGS uses --network host, while the command does not set --host. vLLM therefore listens on host interfaces by default. A network-reachable client can access the unauthenticated API and consume the host GPU. Set an explicit loopback host matching the requested URL.
