```
|
||||
|
||||
## Environment Variables
|
||||
## Configuration Parameters
|
||||
|
||||
You can set your Cohere API key as an environment variable:
|
||||
| Parameter | Description | Type | Default |
|
||||
|-----------|-------------|------|---------|
|
||||
| `model` | Cohere rerank model to use | `str` | `"rerank-english-v3.0"` |
|
||||
| `api_key` | Cohere API key | `str` | `None` |
|
||||
| `top_k` | Maximum documents to return | `int` | `None` |
|
||||
| `return_documents` | Whether to return document texts | `bool` | `False` |
|
||||
| `max_chunks_per_doc` | Maximum chunks per document | `int` | `None` |
|
||||
|
||||
```bash
|
||||
export COHERE_API_KEY="your-cohere-api-key"
|
||||
```
|
||||
## Features
|
||||
|
||||
Then use the config without specifying the API key:
|
||||
- **High Quality**: Enterprise-grade relevance scoring
|
||||
- **Multilingual**: Support for 100+ languages
|
||||
- **Scalable**: Production-ready with high throughput
|
||||
- **Reliable**: SLA-backed service with 99.9% uptime
|
||||
|
||||
```python
|
||||
config = {
|
||||
"reranker": {
|
||||
"provider": "cohere",
|
||||
"config": {
|
||||
"model": "rerank-english-v3.0",
|
||||
"top_n": 10
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
## Best Practices
|
||||
|
||||
## Getting Your API Key
|
||||
|
||||
1. Sign up at [Cohere](https://cohere.ai/)
|
||||
2. Navigate to the API keys section in your dashboard
|
||||
3. Generate a new API key
|
||||
4. Use this key in your configuration
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
- Cohere rerankers work best with 10-100 candidate documents
|
||||
- Higher `top_n` values provide more comprehensive reranking but may increase latency
|
||||
- The v3.0 models generally provide better performance than v2.0 models
|
||||
1. **Model Selection**: Use `rerank-english-v3.0` for English, `rerank-multilingual-v3.0` for other languages
|
||||
2. **Batch Processing**: Process multiple queries efficiently
|
||||
3. **Error Handling**: Implement retry logic for production systems
|
||||
4. **Monitoring**: Track reranking performance and costs

---
|
||||
|
||||
LLM-based reranker provides maximum flexibility by using any Large Language Model to score document relevance. This approach allows for custom prompts and domain-specific scoring logic.
|
||||
|
||||
## Supported LLM Providers
|
||||
|
||||
Any LLM provider supported by Mem0 can be used for reranking:
|
||||
|
||||
- **OpenAI**: GPT-4, GPT-3.5-turbo, etc.
|
||||
- **Anthropic**: Claude models
|
||||
- **Together**: Open-source models
|
||||
- **Groq**: Fast inference
|
||||
- **Ollama**: Local models
|
||||
- And more...
|
||||
|
||||
## Configuration
|
||||
|
||||
```python Python
|
||||
from mem0 import Memory
|
||||
|
||||
config = {
|
||||
"vector_store": {
|
||||
"provider": "chroma",
|
||||
"config": {
|
||||
"collection_name": "my_memories",
|
||||
"path": "./chroma_db"
|
||||
}
|
||||
},
|
||||
"llm": {
|
||||
"provider": "openai",
|
||||
"config": {
|
||||
"model": "gpt-4o-mini"
|
||||
}
|
||||
},
|
||||
"rerank": {
|
||||
"provider": "llm",
|
||||
"config": {
|
||||
"model": "gpt-4o-mini",
|
||||
"provider": "openai",
|
||||
"api_key": "your-openai-api-key", # or set OPENAI_API_KEY
|
||||
"top_k": 5,
|
||||
"temperature": 0.0
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
memory = Memory.from_config(config)
|
||||
```
|
||||
|
||||
## Custom Scoring Prompt
|
||||
|
||||
You can provide a custom prompt for relevance scoring:
|
||||
|
||||
```python Python
|
||||
custom_prompt = """You are a relevance scoring assistant. Rate how well this document answers the query.
|
||||
|
||||
Query: "{query}"
|
||||
Document: "{document}"
|
||||
|
||||
Score from 0.0 to 1.0 where:
|
||||
- 1.0: Perfect match, directly answers the query
|
||||
- 0.8-0.9: Highly relevant, good match
|
||||
- 0.6-0.7: Moderately relevant, partial match
|
||||
- 0.4-0.5: Slightly relevant, limited useful information
|
||||
- 0.0-0.3: Not relevant or no useful information
|
||||
|
||||
Provide only a single numerical score between 0.0 and 1.0."""
|
||||
|
||||
config["rerank"]["config"]["scoring_prompt"] = custom_prompt
|
||||
```
|
||||
|
||||
## Usage Example
|
||||
|
||||
```python Python
|
||||
import os
|
||||
from mem0 import Memory
|
||||
|
||||
# Set API key
|
||||
os.environ["OPENAI_API_KEY"] = "your-api-key"
|
||||
|
||||
# Initialize memory with LLM reranker
|
||||
config = {
|
||||
"vector_store": {"provider": "chroma"},
|
||||
"llm": {"provider": "openai", "config": {"model": "gpt-4o-mini"}},
|
||||
"rerank": {
|
||||
"provider": "llm",
|
||||
"config": {
|
||||
"model": "gpt-4o-mini",
|
||||
"provider": "openai",
|
||||
"temperature": 0.0
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
memory = Memory.from_config(config)
|
||||
|
||||
# Add memories
|
||||
messages = [
|
||||
{"role": "user", "content": "I'm learning Python programming"},
|
||||
{"role": "user", "content": "I find object-oriented programming challenging"},
|
||||
{"role": "user", "content": "I love hiking in national parks"}
|
||||
]
|
||||
|
||||
memory.add(messages, user_id="david")
|
||||
|
||||
# Search with LLM reranking
|
||||
results = memory.search("What programming topics is the user studying?", user_id="david")
|
||||
|
||||
for result in results['results']:
|
||||
print(f"Memory: {result['memory']}")
|
||||
print(f"Vector Score: {result['score']:.3f}")
|
||||
print(f"Rerank Score: {result['rerank_score']:.3f}")
|
||||
print()
|
||||
```
|
||||
|
||||
```text Output
|
||||
Memory: I'm learning Python programming
|
||||
Vector Score: 0.856
|
||||
Rerank Score: 0.920
|
||||
|
||||
Memory: I find object-oriented programming challenging
|
||||
Vector Score: 0.782
|
||||
Rerank Score: 0.850
|
||||
```
|
||||
|
||||
## Domain-Specific Scoring
|
||||
|
||||
Create specialized scoring for your domain:
|
||||
|
||||
```python Python
|
||||
medical_prompt = """You are a medical relevance expert. Score how relevant this medical record is to the clinical query.
|
||||
|
||||
Clinical Query: "{query}"
|
||||
Medical Record: "{document}"
|
||||
|
||||
Consider:
|
||||
- Clinical relevance and accuracy
|
||||
- Patient safety implications
|
||||
- Diagnostic value
|
||||
- Treatment relevance
|
||||
|
||||
Score from 0.0 to 1.0. Provide only the numerical score."""
|
||||
|
||||
config = {
|
||||
"rerank": {
|
||||
"provider": "llm",
|
||||
"config": {
|
||||
"model": "gpt-4o-mini",
|
||||
"provider": "openai",
|
||||
"scoring_prompt": medical_prompt,
|
||||
"temperature": 0.0
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Multiple LLM Providers
|
||||
|
||||
Use different LLM providers for reranking:
|
||||
|
||||
```python Python
|
||||
# Using Anthropic Claude
|
||||
anthropic_config = {
|
||||
"rerank": {
|
||||
"provider": "llm",
|
||||
"config": {
|
||||
"model": "claude-3-haiku-20240307",
|
||||
"provider": "anthropic",
|
||||
"temperature": 0.0
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
# Using local Ollama model
|
||||
ollama_config = {
|
||||
"rerank": {
|
||||
"provider": "llm",
|
||||
"config": {
|
||||
"model": "llama2:7b",
|
||||
"provider": "ollama",
|
||||
"temperature": 0.0
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
- Consider the trade-off between speed and quality
|
||||
|
||||
### Device Optimization
|
||||
- Use GPU (`cuda` or `mps`) for larger models
|
||||
- CPU is sufficient for MiniLM models
|
||||
- Batch processing improves GPU utilization
|
||||
|

|
||||
"provider": "sentence_transformer",
|
||||
"config": {
|
||||
"model": "cross-encoder/ms-marco-MiniLM-L-2-v2", # Smallest model
|
||||
"device": "cpu",
|
||||
"top_n": 5 # Fewer results to process
|
||||
}
|
||||
}
|
||||
}
|
||||
for result in results['results']:
|
||||
print(f"Memory: {result['memory']}")
