PhotoPrism vs SiYuan
A side-by-side editorial comparison of PhotoPrism and SiYuan — release velocity, themes, recent moves, and the top alternatives to consider.
PhotoPrism vs SiYuan: at a glance
What is PhotoPrism?
PhotoPrism swapped in an ONNX vision pipeline, then opened the library to 360° media at 16K.
Two substantial releases in ten weeks moved the product on both axes it cares about. May replaced the legacy Pigo face detector entirely with an ONNX-based pipeline, made vision.yml accept model identifiers from Hugging Face, Ollama and OpenAI-compatible catalogs, and modernised media handling with Vulkan transcoding, a native HEIC/AVIF reader and layered TIFF and PSD support. July added interactive equirectangular 360° photos and video, raised the thumbnail and video ceiling to 16K, and put an inline multi-page PDF viewer in the app.
What is SiYuan?
SiYuan opens 3.8.10 with long-term AI memory and database sub-items.
SiYuan opened the 3.8.10 line with alpha.1 on Oct 31, three days after 3.8.9 reached RC, and alpha.2 followed in under 19 hours with identical notes. The list has 16 items, including workspace-level long-term memory for AI, database sub-items, HTTP requests in templates, an Exa API key option for built-in web search and custom PDF page sizes. No stable 3.8.9 appears in the feed, so rc.1 is the last visible milestone for that line.

PhotoPrism
3.8COLLAB
PhotoPrism swapped in an ONNX vision pipeline, then opened the library to 360° media at 16K.
◆ Current state
Two substantial releases in ten weeks moved the product on both axes it cares about. May replaced the legacy Pigo face detector entirely with an ONNX-based pipeline, made vision.yml accept model identifiers from Hugging Face, Ollama and OpenAI-compatible catalogs, and modernised media handling with Vulkan transcoding, a native HEIC/AVIF reader and layered TIFF and PSD support. July added interactive equirectangular 360° photos and video, raised the thumbnail and video ceiling to 16K, and put an inline multi-page PDF viewer in the app.
◆ Where it's heading
The AI work has moved from bundled TensorFlow models to a pluggable pipeline where the model catalog is configuration, not a build artifact — Ollama, OpenAI and Hugging Face identifiers all resolve through the same file. In parallel the media layer keeps absorbing formats other libraries push out to external tools: PSD, layered TIFF, PDF, and now 360°. PhotoPrism is positioning as the thing you point at a mixed archive, not just a photo folder.
◆ Prediction
Expect the format expansion to continue and the vision configuration to keep broadening its provider surface, with the accessibility section added in July likely to grow into a fuller pass.
SiYuan
5.0COLLAB
SiYuan opens 3.8.10 with long-term AI memory and database sub-items.
◆ Current state
SiYuan opened the 3.8.10 line with alpha.1 on Oct 31, three days after 3.8.9 reached RC, and alpha.2 followed in under 19 hours with identical notes. The list has 16 items, including workspace-level long-term memory for AI, database sub-items, HTTP requests in templates, an Exa API key option for built-in web search and custom PDF page sizes. No stable 3.8.9 appears in the feed, so rc.1 is the last visible milestone for that line.
◆ Where it's heading
The built-in agent keeps gaining context: image extraction from PDFs in 3.8.9, then workspace memory and configurable web search in 3.8.10. Databases keep moving toward structured tooling, with sub-items following block-reference automation, and templates can now reach outside the workspace over HTTP. The release cadence stays fast and noisy, with cumulative notes often repeated across builds.
◆ Prediction
More 3.8.10 alphas are likely within days, given the pace of the 3.8.9 series. When a stable 3.8.9 lands is unclear from the entries.
