but isnβ€˜t this done more strictly in practice (to keep the legal risk minimal)? lots of little hacks here and there but bigger orgs seem to have higher standards, no?

catching up on the search dev room at #FOSDEM: lots of good stuff on fosdem.org/2026/schedul...

glad we (or carly richmond) could put this together again. this won't be the last one.

PS: given our colorful past, it's especially great to be back at FOSDEM pushing the search dev room and OSS :)

jina-clip-v2 uses a multi-task, multi-stage contrastive learning strategy to align multilingual text and image representations to work well at both cross-modal and text-only retrieval. it excels at visually rich documents while flexibly truncating embedding dimensions

ReaderLM-v2 uses a new three-stage data synthesis pipeline called "draft-refine-critique" alongside a unified training framework to transform messy HTML into structured data, making it a highly effective tool that outperforms much larger models on web content extraction

jina-embeddings-v4 works by projecting text & images into a shared semantic space using a unified Qwen2.5-VL backbone and task-specific LoRA adapters, which minimizes the modality gap and enables SOTA retrieval of visually rich documents via single- and multi-vector outputs

Efficient Code Embeddings from Code Generation Models jina-code-embeddings is a novel code embedding model suite designed to retrieve code from natural language queries, perform technical question-answering, and identify semantically similar code snippet...

using a compact autoregressive backbone pre-trained on text and code, along with task-specific instruction prefixes and last-token pooling, jina-code-embeddings generates high-quality embeddings that achieve state-of-the-art performance competitive with much larger models

not sure about the quality other than the claims; there is a more in-depth paper: arxiv.org/abs/2508.06471
but the pricing looks really hard to beat and you can just put it "under" the common tools
