Cohere 发布 Embed 5 系列嵌入模型,Pro 与 Fast 共享同一嵌入空间
Cohere 发布 Embed 5 系列嵌入模型,包含面向最高质量的 Embed 5 Pro 和面向延迟与成本敏感场景的 Embed 5 Fast,两者共享同一嵌入空间,可用 Pro 建索引后用任一模型查询而无需重建索引。Embed 5 支持多模态输入与检索、100 多种语言和 128K token 上下文窗口,Pro 在 ViDoRe V3 上平均得分 85.8,Fast 为 84.5。模型已在 Cohere API、Model Vault、Microsoft Foundry 和 Amazon SageMaker 上线,Pro 定价为每百万 token 0.12 美元,Fast 为 0.08 美元。
res therefore reflect reranking quality rather than first-stage retrieval performance, which we thoroughly evaluate elsewhere against nDCG and Recall. 2 The annotations and code needed to evaluate ViDoRe V3 with RCP-nDCG are available on GitHub. 3 Both sides must use the same output dimension. Compatibility also holds with Matryoshka truncation and int8 quantization, so the same pattern works with compressed indexes. Product Launch; Company News AI isn’t a shortcut. It’s how business gets ahead.
