@JinaAI_ You guys haven’t made small (<100M) models in quite some time. I’d love to see a small variant of your v5 text models. 331 views · 1 likes · 0 reposts · 0 replies Open on X →

Per-task performance across 13 task types. Gold stars mark tasks where jina-embeddings-v5-omni-small beats the best open-weight baseline (3-9x larger). Wins: image classification (68.55 vs 64.30), image clustering (84.57 vs 83.24), audio classification (55.89 vs 53.39). Main http 2.4K views · 8 likes · 0 reposts · 1 replies Open on X →

v5-omni keeps the v5-text backbone completely frozen and adds pretrained vision and audio encoders connected through small trainable projectors: - Vision: Qwen3.5 vision encoders with 2x2 spatial merge. We freeze everything except the final projection layer (fc_vision_2), which 3.8K views · 13 likes · 1 reposts · 2 replies Open on X →

jina-embeddings-v5-omni is here! Our first universal embedding model for text, images, audio, and video. Available in two sizes: small (1.57B, 1024-dim, 32K context) and nano (0.95B, 768-dim, 8K context). Both support Matryoshka truncation down to 32 dimensions. v5-omni is http 135.6K views · 585 likes · 91 reposts · 12 replies Open on X →

Most don't know (1) how easy it is to invert embedding vectors back into sentences, (2) this is a perfect task text diffusion models. Here's a 78M parameter model and live demo that recovers 80% of tokens from Qwen3-Embedding and EmbeddingGemma vectors. Works even on multilingual 13.2K views · 173 likes · 21 reposts · 7 replies Open on X →

jina-reranker-v3 was the first listwise reranker to throw all documents into one context window (where traditional rerankers loop over ⟨q,d⟩ pairs) and let them fight it out via self-attention—what we call "last but not late" interaction. Bold or stupid? But not mediocre. Today h 7.4K views · 91 likes · 14 reposts · 1 replies Open on X →
