Elastic Unveils Powerful, Compact Models for Semantic Search
Elastic announced the availability of jina-embeddings-v5-text, a family of two small, Elasticsearch-native multilingual embedding models (239M and 677M parameters) designed for high-performance semantic search. Elastic claims these compact models outperform much larger 7B–14B parameter models on key search and semantic tasks and achieve best-in-class results on the MMTEB benchmark among comparable-size models. The small footprint aims to enable lower infrastructure costs, faster queries, hybrid search, and deployment in memory- or compute-constrained environments. The models are available as open weights on HuggingFace for self-hosted inference via vLLM, llama.cpp or MLX, and via Elastic Inference Service (EIS), a GPU-accelerated inference-as-a-service integrated with Elastic’s stack.
Elastic’s Elasticsearch-native embeddings and EIS availability reduce infrastructure cost and expand deployment options for high-performance semantic search and RAG workflows, affecting search/AI infrastructure adoption across enterprises.

Elastic Launches Jina v5 Omni Multimodal Embeddings
Elastic announced jina-embeddings-v5-omni, a new family of multimodal embedding models that represent text, images, video, and audio as vectors. The omni family is available in two sizes (small and nano) and shares the same text embedding space as jina-embeddings-v5-text, enabling teams to reuse existing v5 text indexes and immediately index multimedia without re‑indexing. The models use a single universal language model aligning modalities, offer a modular design to toggle modality processing, adjustable embedding sizes, and optimizations (quantization) for lower storage and compute. Elastic cited independent benchmark results claiming frontier-class performance across audio (MAEB), image (MIEB, ViDoRe), text (MMTEB), and video (MMEB-v2). The announcement was published May 11, 2026.
Elastic Offers Jina On-Prem Semantic Search
Elastic announced that Jina AI models are now available for on-premises and air-gapped deployments via Jina On-Prem. The offering packages 28 Jina AI models covering text, images, audio, and video into a single embedding space that runs entirely within customer environments with no outbound network calls, telemetry, or license servers. Jina On-Prem supports CPU and GPU (automatic GPU detection), can run small models on a single 8GB GPU, and is presented as a drop-in replacement for models served through Elastic Inference Service (EIS) for air-gapped Elastic deployments.
Google DeepMind launches Gemma 4 multimodal models
Google DeepMind released Gemma 4, a family of open-weight multimodal models distributed under an Apache 2.0 license. Gemma 4 includes multiple sizes — notably a 31B dense model, a 26B MoE variant (“A4B”, ~4B active), and two edge-focused effective models (E4B, E2B) with native text, vision and audio inputs — and supports very long contexts (up to 256K tokens for large models). Early community benchmarks and leaderboards report strong reasoning and token-efficiency signals for the 31B variant, and Day‑0 ecosystem support appeared across local and serving stacks (llama.cpp, Ollama, vLLM, LM Studio, transformers.js). The release emphasizes on-device/edge deployment, agent workflows and structured outputs (function-calling/JSON). Reported architectural notes include MoE blocks, per-layer embeddings, KV-cache sharing and proportional RoPE, though some analyses attribute the gains largely to training recipe and data improvements.
