To run the model on GPU, you need to install Flash Attention. You may either install from pypi (which may not work with fused-dense), or from source. To install from source, clone the GitHub repository: The code provided here should work with commit `43950dd`. Change to the cloned repo and install: If you would like to use fused MLPs (e.g. to use activation checkpointing), you may install fused-dense also from source:

`jina-clip-v1` is a state-of-the-art English **multimodal (text-image) embedding model**. Traditional text embedding models, such as jina-embeddings-v2-base-en, excel in text-to-text retrieval but incapable of cross-modal tasks. Models like openai/clip-vit-base-patch32 effectively align image and text embeddings but are not optimized for text-to-text retrieval due to their training methodologies and context limitations. `jina-clip-v1` bridges this gap by offering robust performance in both domains. Its text component matches the retrieval efficiency of `jina-embeddings-v2-base-en`, while its overall architecture sets a new benchmark for cross-modal retrieval. This dual capability makes it an excellent tool for multimodal retrieval-augmented generation (MuRAG) applications, enabling seamless text-to-text and text-to-image searches within a single model.

This model is based on the paper jina-clip-v2: Multilingual Multimodal Embeddings for Text and Images. `jina-clip-v2` is a **general-purpose multilingual multimodal embedding model for text & images**. Multimodal embeddings enable searching and understanding data across different modalities through a coherent representation. They serve as the backbone of neural information retrieval and multimodal GenAI applications.

`jina-code-embeddings` is an embedding model for code retrieval. The model supports various types of code retrieval (text-to-code, code-to-code, code-to-text, code-to-completion) and technical question answering across 15+ programming languages. Built on Qwen/Qwen2.5-Coder-0.5B, `jina-code-embeddings-0.5b` features: - **Multilingual support** (15+ programming languages) and compatibility with a wide range of domains, including web development, software development, machine learning, data science, and educational coding problems. - **Task-specific instruction prefixes** for NL2Code, Code2Code, Code2NL, Code2Completion, and Technical QA, which can be selected at inference time. - **Flexible embedding size**: dense embeddings are 896-dimensional by default but can be truncated to as low as 64 with minimal performance loss.

JinaColBERT V2 (`jina-colbert-v2`) is a new model based on the JinaColBERT V1 that expands on the capabilities and performance of the `jina-colbert-v1-en` model. Like the previous release, it has Jina AI’s 8192 token input context and the improved efficiency, performance, and explainability of token-level embeddings and late interaction. - Multilingual support for dozens of languages, with strong performance on major global languages. - Matryoshka embeddings, which allow users to trade between efficiency and precision flexibly. - Superior retrieval performance when compared to the English-only `jina-colbert-v1-en`. JinaColBERT V2 offers three different versions for different embeddings dimensions: `jinaai/jina-colbert-v2`: 128 dimension embeddings `jinaai/jina-colbert-v2-96`: 96 dimension embeddings `jinaai/jina-colbert-v2-64`: 64 dimension embeddings

可以调整厂商、分类或输入输出条件;新模型正持续收录。
调整月度 Token 用量,直观比较不同模型的预估 API 开支。
使用已采集且单位可比的 USD / 百万 Token 渠道报价。报价为采集时快照;不计缓存优惠、阶梯价、推理额外输出与税费,请以来源的当前报价为准。
先区分输入、输出和缓存价格,再使用同一任务和用量估算总费用。图像、音频和视频可能按张、时长或分辨率计费,不能直接与 Token 单价比较。
不一定。必须逐一核对具体模型版本的许可证、商用限制及使用政策。自己部署还需要考虑显存、推理资源和运维费用。
榜单取决于测试任务、版本与评测方法。建议用实际业务样本比较准确性、时延、稳定性和成本,再选择模型。
