Function createCohereReranker

@memberjunction/ai-cohere

Cohere AI provider for MemberJunction. Currently provides reranking capabilities using Cohere's Rerank API.

Supported models:

• rerank-v3.5: Latest English reranker with best accuracy
• rerank-multilingual-v3.0: Supports 100+ languages

API Key: The legacy environment-variable fallback is named after the model-vendor row's driver class: AI_VENDOR_API_KEY__COHERERERANKER for the shipped Cohere reranker models. A Cohere credential binding takes precedence over it.

Usage:

import { CohereReranker } from '@memberjunction/ai-cohere';

// Create instance via ClassFactory
const reranker = ClassFactory.CreateInstance<BaseReranker>(
    BaseReranker,
    'CohereLLM',
    apiKey,
    'rerank-v3.5'
);

const response = await reranker.Rerank({
    query: 'What is the capital of France?',
    documents: [
        { id: '1', text: 'Paris is the capital of France.' },
        { id: '2', text: 'London is in England.' }
    ],
    topK: 5
});
