4. Enjoy intelligent Q&A experience!

💡 Usage Tip: When knowledge base is enabled, system automatically loads latest configuration and prioritizes knowledge base services.

BIC-QA supports custom prompts and retrieval parameters with three preset modes:

Configurable Parameters:

• Prompt: System instruction template
• Temperature: Controls response randomness
• Similarity: Knowledge base retrieval threshold
• TopN: Number of retrieval results

⚠️ Parameter Impact: Higher temperature increases creativity, similarity/TopN affects knowledge base retrieval scope and quantity.

Possible Causes:

• File corruption during extraction
• Browser didn't select the innermost folder when choosing plugin

Solutions:

• Selected folder should contain manifest.json as shown below:

Possible Causes:

• Incorrect model service address
• Network connection issues
• Invalid API Key
• Local model permissions not granted

Solutions:

# Check service address
curl http://localhost:11434/v1/models

# Verify network connection
ping your-api-endpoint.com

# Configure local environment variables
Set system variable OLLAMA_ORIGINS to *

Possible Causes:

• Ollama service not started
• Incorrect API address format
• Model not properly deployed

Solutions:

# Start Ollama service
ollama serve

# Check model list
ollama list

Possible Causes:

• Incorrect knowledge base service URL
• Expired or invalid API Key
• Network permission restrictions

Solutions:

• Check knowledge base service status
